Frequently Asked Questions

Q1: What is a securities litigation expert witness?
Not every financial dispute comes with a simple answer. A securities litigation expert witness digs into the data - market behavior, investor losses, causation and gives courts the economic clarity needed to reach the right outcome.
Q2: What does an event study show in securities fraud cases?
When a company makes a disclosure, did the stock move because of it - or was something else going on? An event study answers that question statistically, and in securities fraud cases, that answer often determines whether a class gets certified and how much investors recover.
Q3: How are damages calculated in a securities class action?
Investor losses don't calculate themselves. Dr. Kumar builds the econometric models that show exactly how much an inflated stock price cost shareholders - using trading data, financial disclosures, and methodology that holds up when opposing counsel pushes back.
Q4: Can an expert witness work for both plaintiff and defense?
Yes. Dr. Kumar works as an independent expert for both plaintiff and defense counsel, depending on the matter. Her role is to provide objective, data-driven analysis - not to advocate for a particular outcome.
Q5: What industries does Dr. Kumar cover?
Financial disputes don't stay in one lane, and neither does Dr. Kumar. She has worked across financial services, technology, healthcare, energy, and consumer goods - covering public companies, private enterprises, and complex structured products.
Q6: Does Dr. Kumar provide consulting-only support, or only testifying?
Dr. Kumar works both in front of the court and behind the scenes. Whether she's on the stand or helping counsel pick apart an opposing expert's methodology, she's fully engaged from the earliest stages of a case through verdict.
