Introduction to Calculating Damages in Securities Litigation

Calculating damages in securities litigation is a complex and intricate process that requires a thorough understanding of both legal and financial principles. In securities litigation, damages typically refer to the monetary compensation sought by investors who have suffered losses due to fraudulent activities, misrepresentations, or other violations of securities laws. The primary objective in calculating damages is to accurately quantify the financial harm that investors have endured, ensuring that they are fairly compensated for their losses.

The process of calculating damages in securities litigation involves several key steps. First, it is essential to establish a clear timeline of events, identifying when the alleged misconduct occurred and when the investors purchased or sold the securities in question. This timeline helps in determining the period during which the investors were affected by the wrongful actions.

Next, it is crucial to assess the impact of the misconduct on the value of the securities. This often requires a detailed analysis of market conditions, industry trends, and company-specific factors that may have influenced the security’s price.

One commonly used method for calculating damages in securities litigation is the “event study” methodology. This approach involves examining the stock price movements around the time of the alleged misconduct and isolating the effects of the wrongdoing from other market factors.

By comparing the security’s performance to a benchmark index or similar securities, analysts can estimate the extent to which the misconduct contributed to the investors’ losses. Another method is the “out-of-pocket” approach, which calculates damages based on the difference between the price paid for the security and its true value after correcting for the fraud or misrepresentation.

Another method refered to as the “Market-adjusted damages” theory argues that the decline in stock price was caused by broader market trends, not just the company’s fraud.  Accurate calculation of damages in securities litigation also requires collaboration with experts in finance, economics, and law.

Financial analysts and economists play a pivotal role in developing robust models and conducting empirical analyses to support damage claims. Legal experts ensure that the calculations adhere to relevant legal standards and precedents, providing a solid foundation for presenting the case in court.

In conclusion, calculating damages in securities litigation is a multifaceted endeavor that necessitates a deep understanding of both financial markets and legal frameworks. By employing rigorous methodologies and enlisting the expertise of professionals, it is possible to achieve a fair and accurate assessment of investor losses. This ensures that victims of securities fraud or misconduct receive appropriate compensation, thereby upholding the integrity of financial markets and fostering investor confidence.

Types of Damages in Securities Class Actions

The most common type of damages in a securities class action lawsuits is  out-of-pocket loss, which is typically calculated based on the decline in a company’s stock price after a fraudulent misstatement is revealed. Punitive damages are rarely awarded in securities class actions but may be relevant in other fraud cases.

Out-of-pocket damages in securities class action lawsuits

This damage model is the standard for most securities class action lawsuits, brought under Rule 10b-5. The goal is to compensate investors by putting them back in the position they would have been in if the fraud had never occurred.
Key cases defining and applying the out-of-pocket damages model for securities fraud under Rule 10b-5 include Affiliated Ute Citizens v. United States and Dura Pharmaceuticals, Inc. v. Broudo. These cases establish that plaintiffs can recover the difference between the price paid and the security’s actual value, but only if they can prove the fraud caused the loss.

Example of an out-of-pocket calculation

  1. A company’s stock trades at $50 per share due to fraudulent financial statements.
  2. An investor buys the stock at $50 per share.
  3. The fraud is revealed, and the stock price drops to $40 per share.
  4. The investor’s out-of-pocket damages would be $10 per share, representing the amount of inflation caused by the fraud ($50 purchase price – $40 true value).

Landmark cases on out-of-pocket damages in securities class action lawsuits

Affiliated Ute Citizens v. United States (1972)

This Supreme Court decision is considered the foundational case for the modern interpretation of out-of-pocket damages under Rule 10b-5.
  • Case summary: The case involved bank employees who defrauded members of the Ute Indian tribe by inducing them to sell their shares in a tribal corporation for significantly less than their true market value.
  • Legal principle: The Court affirmed that the out-of-pocket measure of damages was appropriate for a Rule 10b-5 violation. It held that the bank employees had an affirmative duty to disclose relevant information to the unsophisticated sellers and that their failure to do so constituted fraud.
  • Significance: This case established the out-of-pocket measure as the “usual form of relief” for securities fraud and confirmed that the remedy was not limited to face-to-face transactions.
This is the most critical modern Supreme Court decision on securities fraud damages. It clarified the concept of “loss causation” in the context of publicly traded securities.
  • Case summary: Shareholders of Dura Pharmaceuticals sued the company after its stock price dropped following a corrective disclosure that revealed the truth about the company’s false representations regarding its earnings and a new medical device.
  • Legal principle: The Court unanimously held that plaintiffs in a securities fraud in securities class action lawsuits must plead and prove more than an artificially inflated purchase price. They must also show that the defendant’s fraud caused their actual economic loss when the stock price later declined after the truth became known. The price decline must be connected to the corrective disclosure, not unrelated factors like broader market trends.
  • Significance:Dura effectively closed a loophole that allowed plaintiffs to recover damages for price inflation alone, without proving that the fraud itself caused a loss. It reinforced the requirement that the out-of-pocket loss must be causally linked to the defendant’s misconduct.

Other notable cases

  • Basic Inc. v. Levinson (1988): While primarily known for establishing the “fraud-on-the-market” theory, this case is a precursor to Dura. It addressed a fraud perpetrated in an impersonal, open market and allowed for a presumption of reliance, which is necessary for a Rule 10b-5 class action. This theory allows plaintiffs to sue without proving they relied on a specific misstatement, because the market price is presumed to be reliable.
  • Harris v. American Investment Co. (1975): This is one of many circuit court cases that applied the out-of-pocket damages rule in the years after Affiliated Ute. It reinforced the notion that a defrauded buyer could recover the difference between the price they paid and the market price after the public discovered the fraud.

Fraud on the market theory in securities class actions

Under this theory in securities class actions, a company’s stock price is presumed to be artificially inflated by material misstatements or omissions. The out-of-pocket loss is the difference between the price an investor paid for the stock and the stock’s “real” value at the time of purchase.
  • Purchase price: The price the investor paid for the security.
  • “Real” value at the time of purchase: The price the stock would have been without the inflation caused by the fraud.
  • Price drop after corrective disclosure: The amount of inflation is typically estimated by measuring the stock price decline immediately after the fraudulent information is disclosed to the market.

Key Cases on Fraud on the market theory in securities class actions

Key Supreme Court cases that in securities class actions have defined and refined the “fraud-on-the-market” theory in securities litigation include Basic Inc. v. Levinson and two decisions involving Halliburton Co. These cases established the theory, affirmed its legal basis, and clarified the standards for invoking and rebutting its presumption of reliance.
Basic Inc. v. Levinson (1988)
In this landmark decision, the Supreme Court adopted the fraud-on-the-market theory, establishing a rebuttable presumption of reliance for investors in securities class actions. The Court reasoned that market prices in an efficient market reflect all public information, including misstatements, and investors rely on the integrity of these prices. To invoke the presumption, plaintiffs must show a public, material misrepresentation, trading in an efficient market, and purchasing stock between the misrepresentation and truth disclosure. Defendants can rebut the presumption by showing the misrepresentation did not affect the stock price.
Halliburton Co. v. Erica P. John Fund, Inc. (Halliburton II) (2014)
This case reaffirmed the fraud-on-the-market theory in securities litigation while allowing defendants to challenge class certification. The Court held that defendants could present evidence that alleged misrepresentations did not impact stock price at the class certification stage, giving defendants a way to argue that individual reliance issues, rather than common issues, predominate.
Goldman Sachs Group, Inc. v. Arkansas Teacher Retirement System (2021)
This case addressed the application of the theory to generic statements. The Court ruled that the generic nature of a misrepresentation can be considered when evaluating a defendant’s rebuttal evidence at the class certification stage. The ruling allows defendants to use the genericness of their statements as evidence against a presumption of price impact, potentially making it harder for plaintiffs in securities class actions to maintain class certification in certain cases.

Additional factors in damage calculation

Market-adjusted damages

A defense can argue that the decline in stock price was caused by broader market trends, not just the company’s fraud, referred to as Market-adjusted damages. To account for this, damages can be adjusted by benchmarking against a relevant market index, like the S&P 500, to isolate the harm caused specifically by the fraud.
Cases illustrating the “market-adjusted damages” defense—which attempts to separate losses caused by a company’s fraud from those caused by broader market trends—center on the concept of loss causation, which the Supreme Court clarified in Dura Pharmaceuticals, Inc. v. Broudo (2005). This defense, often presented through expert testimony, aims to reduce damages by showing other factors contributed to a stock’s decline such as market-adjusted damages.
Landmark case on separating fraud from market factors: 
Dura Pharmaceuticals, Inc. v. Broudo (2005)
This Supreme Court decision is the cornerstone for challenging damages based on market fluctuations.
  • Case summary: Shareholders sued Dura after its stock fell following a disappointing earnings report. The plaintiffs alleged that prior misrepresentations had artificially inflated the purchase price of the stock.
  • Legal principle: The Court rejected the argument that an inflated purchase price alone was sufficient to prove loss causation. Instead, it required plaintiffs to prove that the fraud—not other market forces—was the proximate cause of their economic loss. The stock price had to drop after the fraudulent information was revealed, and this drop had to be connected to the fraud itself.
  • Significance:  Dura allows defendants to argue that a stock’s decline was the result of a general market downturn or other non-fraudulent company-specific news. To counter this, plaintiffs must use expert analysis, such as event studies, to isolate the price drop caused by the fraud from other contributing factors.

Practical application of the defense

Event studies in litigation
Following Dura, courts rely on sophisticated financial and statistical analyses, known as event studies, to disentangle market-wide and industry-wide movements from the price decline caused by the defendant’s alleged fraud.
Post-Dura applications
  • Federal court cases: Federal courts now routinely require plaintiffs to address competing causes for stock price declines. In a case involving a whistleblower report, a court noted that a 7.4% stock decline might seem insignificant when compared to historical volatility but could be deemed significant if peer companies experienced gains on the same day. This highlights the need for expert analysis that accounts for all market movements.
  • Settlement context: This defense is a powerful tool during settlement negotiations. The threat of a defendant’s expert effectively separating the fraud from other market losses can pressure plaintiffs to accept a lower settlement amount.
Statutory limitations on damages
The Private Securities Litigation Reform Act (PSLRA) further supports this approach by capping damages in some cases, an implicit recognition that a stock’s price drop following a corrective disclosure can be influenced by multiple factors. The damages are limited based on the stock’s average trading price during the 90-day period after a corrective disclosure, which can reduce the recovery if the stock’s price rebounds during that time.
In re: Mego Financial Corp. Securities Litigation (9th Cir. 2000)
This case provides a clear example of how the PSLRA’s 90-day “look back” provision limits damages in a securities fraud class action. The decision from the Ninth Circuit Court of Appeals explains how a stock’s rebound following a corrective disclosure can reduce or even eliminate a plaintiff’s recoverable damages.
Case background
  • The lawsuit: Shareholders of Mego Financial Corp. brought a securities fraud class action against the company for alleged misstatements that inflated its stock price.
  • The corrective disclosure: The truth about the alleged fraud was eventually revealed, leading to a significant drop in Mego’s stock price.
  • The stock’s recovery: In the 90-day period after the corrective disclosure, Mego’s stock price rebounded. 
The court’s interpretation
Significance
  • Real-world application: In re: Mego Financial is a critical example showing how the 90-day look-back provision works in practice. It demonstrates that the stock price on the day the fraud is revealed is not necessarily the final determinant of damages.
  • Impact on plaintiffs: The ruling confirms that plaintiffs who purchased inflated stock and held it through a market rebound can have their damages significantly reduced or wiped out by the PSLRA cap, even if they suffered a short-term loss.
  • Implications for settlements: The existence and potential effect of the 90-day look-back provision are important factors in settlement negotiations. If a stock has shown a strong recovery, a plaintiff’s realistic damage claim will be constrained, influencing the settlement amount.

Trading models for complex calculations

For more complex cases, such as those involving stock options, trading models are used to calculate aggregate damages. These models track which shares are eligible for damages, distinguishing between shares bought and sold within the class period (“in-and-out damages”) and those held throughout (“retention damages”).

Damage calculation in settlements

The vast majority of securities class actions are settled, not litigated to a verdict.
  • Settlement fund distribution: A court-appointed administrator distributes the settlement fund after deducting attorney fees and legal costs.
  • Pro rata distribution: Payouts are often allocated on a pro rata basis, meaning they are divided among eligible class members based on their individual losses.
  • Lead plaintiff compensation: The lead plaintiff or plaintiffs may receive a larger portion of the settlement in recognition of their more significant role in the litigation.

Summary

Type of DamagesCase NameHolding
Out-of-Pocket LossAffiliated Ute Citizens v. United States (1972)The U.S. Supreme Court established the “out-of-pocket” measure as the standard for damages in securities fraud cases under Rule 10b-5. The holding confirmed that defrauded investors should be compensated for the difference between what they paid for a security and its true value at the time of purchase.
Fraud-on-the-Market TheoryBasic Inc. v. Levinson (1988)The Supreme Court adopted the “fraud-on-the-market” theory, which creates a rebuttable presumption of reliance for investors in efficient markets. The Court held that an investor relies on the integrity of the market price, which is presumed to reflect all public information, including any fraudulent misstatements.
Fraud-on-the-Market (Rebuttal)Halliburton Co. v. Erica P. John Fund, Inc. (Halliburton II) (2014)This case reaffirmed the “fraud-on-the-market” theory but clarified that defendants can rebut the presumption of reliance at the class certification stage. Defendants can introduce evidence showing that the alleged misrepresentation did not actually impact the stock price.
Fraud-on-the-Market (Generic Statements)Goldman Sachs Group, Inc. v. Arkansas Teacher Retirement System (2021) [The Supreme Court ruled that the generic nature of a company’s alleged misstatements can be considered when evaluating a defendant’s rebuttal evidence. This means a defendant can argue that a vague or general misstatement was unlikely to impact the stock price, making it harder for plaintiffs to maintain class certification.
Market-Adjusted Damages (Loss Causation)Dura Pharmaceuticals, Inc. v. Broudo (2005) [3, 5]The Court required plaintiffs to prove “loss causation” in securities fraud cases involving publicly traded stock. An investor must demonstrate that the fraudulent misstatement or omission directly caused their economic loss, not that they simply purchased the stock at an inflated price. This allows for defenses arguing that broader market or industry trends, rather than the fraud, caused the stock’s decline.
Statutory Damages Limitation (PSLRA)In re: Mego Financial Corp. Securities Litigation (9th Cir. 2000) [6]The Ninth Circuit interpreted the Private Securities Litigation Reform Act (PSLRA) 90-day “look-back” provision. It held that if a stock’s price recovers in the 90 days after a corrective disclosure, the recoverable damages for a class of investors can be reduced or eliminated entirely.

Common methods for estimating damages

Economic experts use several methodologies to calculate and prove the amount of artificial price inflation:

1. Event study analysis

An event study is a statistical analysis used to isolate the impact of a specific piece of news (the “event”) on a company’s stock price. 
  • Process: Experts examine the stock price and broader market movements around the date of a “corrective disclosure”—when the market first learns the concealed truth.
  • Goal: The study removes the effect of general market or industry trends to identify the “abnormal return” or price drop directly attributable to the corrective news. This drop is used to estimate the per-share price inflation.

2. Constant inflation method in securities litigation

This method estimates the artificial inflation by assuming it remained at a consistent level throughout the class period, after being established by a corrective disclosure.
  • Constant ribbon: Assumes that the absolute dollar amount of inflation per share remains fixed over the class period.
  • Constant percentage: Assumes the percentage of inflation remains fixed, which causes the dollar amount of inflation to fluctuate with the changing stock price. This can increase damage estimates earlier in the class period when the stock price was higher.

3. Market-adjusted damages (for individual investors)

In cases involving financial advisors, a “well-managed portfolio” (WMP) approach may be used to calculate damages.

The Private Securities Litigation Reform Act (PSLRA)

The PSLRA, passed in 1995, includes specific rules that affect damage calculations.
  • 90-day lookback period: The recoverable damages are limited by comparing the purchase price with the mean trading price of the security during the 90-day period following the corrective disclosure. This prevents plaintiffs from benefiting from an immediate, sharp drop in price if the stock quickly rebounds.
  • Example: If a stock dropped to $5 but rebounded to a 90-day mean trading price of $10, damages would be calculated based on the $10 figure, not the initial $5 low.

Challenges and complexities

  • Sorting fraud from noise: Experts must distinguish the stock price decline caused by fraud from the “market noise” caused by other variables, which can lead to battles between expert witnesses.
  • Determining materiality: Only material misrepresentations are actionable. Event studies can help quantify whether a specific piece of information was considered important enough by the market to impact the stock price.
  • Accounting for risk: Some researchers argue that standard methods fail to account for how a fraud revelation can increase a stock’s perceived risk, which should be factored into the damage calculation.

Calculating damages in securities litigation involves evaluating various factors such as the timing of transactions, the impact of misrepresentations or omissions on stock prices, and the overall market conditions at the time of the alleged fraud.

Other Methods Besides Event Studies to Show Loss Causation in Securities Class Action Lawsuits

In securities fraud cases, plaintiffs can establish loss causation through several methods beyond event studies, though an event study is often considered the “gold standard”. Other methods focus on demonstrating the link between the fraudulent misrepresentation and the investor’s loss by highlighting the revelation of the truth and the subsequent market reaction.

Theories of disclosure and market reaction

Gradual or “leakage” disclosure

Loss causation can be proven even if a company never issues a single corrective disclosure. The truth about the fraud can emerge over time through a series of smaller, partial disclosures, news articles, or analyst reports.

In Mineworkers’ Pension Scheme v. First Solar Inc. (2018), the Ninth Circuit Court of Appeals clarified the standard for “loss causation” in securities fraud cases under Section 10(b) of the Securities Exchange Act of 1934. The court held that plaintiffs can prove loss causation using a general proximate cause test, without being required to show that the defendant’s fraud was explicitly revealed to the market.

Background
The case involved investors, including the Mineworkers’ Pension Scheme, who purchased stock in solar panel manufacturer First Solar between 2008 and 2012. The investors alleged that First Solar and its executives concealed defects in its solar panels, leading to premature power loss and significant warranty liabilities.
As these issues were gradually disclosed, First Solar’s stock price dropped significantly. First Solar sought summary judgment, arguing that the investors could not prove loss causation because the market hadn’t been explicitly informed of the fraud. The district court denied this but certified the question of the proper loss causation standard to the Ninth Circuit.
The Ninth Circuit’s ruling on loss causation
The Ninth Circuit affirmed the district court’s decision, rejecting the need for a strict “revelation of fraud” standard. The court stated that the test for loss causation is the “familiar test for proximate cause,” requiring a causal link between the misrepresentation and the investor’s loss. It found no legal requirement that the market must learn of the fraud itself.
Instead, showing that the market reacted negatively to the true facts that were previously misrepresented or concealed is sufficient, supporting a “truth-on-the-market” theory where gradual disclosures can establish causation. This ruling resolved an internal conflict within the Ninth Circuit but created a wider split with other circuits that require a more direct revelation of fraud.
Subsequent settlement
Although the Mineworkers’ appeal addressed a key legal standard, the litigation concluded with a settlement. Shortly before the trial was set to begin in 2020, First Solar agreed to a $350 million settlement to resolve the class action for investors who purchased stock between April 30, 2008, and February 28, 2012.

Materialization of the risk

This theory holds that when a company makes misrepresentations to hide a material business risk, the loss can occur when that risk later materializes. The eventual price decline is directly linked to the misstatement. 
  • Example: If a company falsely assures investors that it has a sound cybersecurity program and is then hit with a massive data breach, the subsequent stock drop can be attributed to the fraud. The materialization of the risk, not an official confession, proves the loss.
  • Key evidence: Plaintiffs would need to show the causal chain between the original misrepresentation and the event that caused the loss. 

Evidence of artificial inflation

Pleading an inflated purchase price

Before the Supreme Court’s ruling in Dura Pharmaceuticals, Inc. v. Broudo, some circuit courts, like the Ninth Circuit, followed a “price inflation” theory of loss causation. While Dura overturned this liberal standard, some courts have given the corrective disclosure requirement a relaxed reading.
  • Prior to Dura: Plaintiffs only had to allege that they purchased the security at an artificially inflated price.
  • After Dura: Plaintiffs must show that the fraud caused a subsequent decline in the stock’s price. However, some legal scholars and plaintiffs argue that in certain circumstances, a complaint that sufficiently identifies the cause of the price inflation can still be considered.

Judicial and evidentiary considerations

The use of transaction and loss causation

In certain non-efficient market cases (such as face-to-face transactions), courts distinguish between transaction causation and loss causation. 
  • Transaction causation: The plaintiff must show that they would not have purchased the security “but for” the misrepresentation.
  • Loss causation: The untruth was responsible for the loss in a “reasonably direct or proximate way”. 

Pleading and evidentiary standards

While event studies are often used to prove loss causation in securities fraud class actions, some legal scholars argue that courts’ reliance on them is inconsistent with federal securities laws.

Key challenges in damage assessments

Isolating fraud from market “noise”

  • Confounding factors: Stock price movements are influenced by a wide array of variables, including overall market trends, industry-wide news, and company-specific information unrelated to the fraud. This makes it difficult to definitively attribute a stock price drop solely to a corrective disclosure.
  • Competing expert opinions: Expert economists, often using event study methodologies, frequently present contradictory testimony by emphasizing or minimizing the role of confounding factors. A plaintiff’s expert may attribute most of a stock drop to the fraud, while a defendant’s expert might argue the decline was caused by general market conditions.

The limitations of event studies

  • Multiple disclosures: Event studies are less effective when multiple news items are released simultaneously or in close succession, making it difficult to isolate the impact of the specific corrective disclosure.
  • Statistical power: For single-firm analyses, standard event studies may have low statistical power and lack the ability to detect price impacts unless the effects are substantial. This can lead to economically significant frauds being overlooked and can potentially create an upward bias in damage estimates for frauds that are detected.
  • Market volatility: High market volatility, such as during a financial crisis, can make it particularly difficult for event studies to produce reliable results, potentially leading to biased inferences.

The impact of the Goldman Sachs v. Arkansas Teacher Retirement System ruling

  • Generic statements: The 2021 Supreme Court ruling allowed defendants to present evidence that an alleged misrepresentation was “too generic” to have an impact on the company’s stock price.
  • Mismatch between statement and disclosure: Lower courts have applied this rationale to find a “considerable mismatch between the generic nature of the alleged misrepresentations and the specific revelation” of fraud, leading to decertification of class actions. This creates a significant challenge for plaintiffs trying to link broad, positive statements to later, more specific disclosures of misconduct.

Estimating damaged shares

  • Inferring trading behavior: Experts must use complex statistical models to infer the trading activity of a class of investors, as comprehensive trading records are not available for all members. This adds an element of estimation and uncertainty to the calculation.
  • Varying inflation: The amount of artificial price inflation can fluctuate throughout a class period, and different investors may be harmed to different degrees depending on when they bought and sold their shares. This complicates efforts to establish a uniform measure of damages.

Timing and market overreaction

  • PSLRA’s 90-day lookback: ThePSLRA limits damages to the difference between the plaintiff’s purchase price and the average trading price in the 90 days following a corrective disclosure. This was intended to curb excessive awards based on temporary price drops. However, some critics argue this creates a new set of challenges and could create incentives for plaintiffs to time their sales.

Case Studies: Notable Securities Litigation Outcomes

Numerous landmark cases illustrate the complexities and outcomes of securities litigation, particularly concerning damages. These case studies highlight the scale of recoveries, the challenges involved in proving fraud and loss causation, and the evolving landscape of securities law.

Conclusion

In conclusion, calculating damages in securities litigation is a critical aspect of financial and legal proceedings. It requires a comprehensive understanding of both market dynamics and legal principles to ensure that the financial compensation awarded is just and accurate. In securities litigation, calculating damages involves evaluating various factors such as the timing of transactions, the impact of misrepresentations or omissions on stock prices, and the overall market conditions at the time of the alleged fraud.

Experts in the field must employ sophisticated financial models and statistical analyses to determine the extent of economic harm suffered by investors. This process not only facilitates fair restitution for affected parties but also upholds the integrity of the securities market by deterring fraudulent activities.

Moreover, the complexities in calculating damages in securities litigation underscore the need for specialized knowledge and expertise. Legal professionals, financial analysts, and forensic accountants often collaborate to dissect intricate financial data and present clear, precise damage estimates in court.

The methodologies used can vary, including event studies, loss causation analysis, and market-adjusted return models, all aimed at isolating the impact of fraudulent activities from other market influences. By doing so, courts can make informed decisions that reflect the true economic losses incurred by plaintiffs.

As we approach the future, advancements in technology and data analytics are likely to further refine the process of calculating damages in securities litigation. Enhanced computational tools and more robust datasets will enable practitioners to perform even more precise and reliable damage assessments.

Ultimately, these improvements will contribute to a more equitable legal system where victims of securities fraud receive appropriate compensation throuog securities litigation, promoting a healthier and more transparent investment environment.
