The study looked at how a law called the Private Securities Litigation Reform Act of 1995 affected lawsuits for securities fraud. The law didn't change how many companies got sued, but it did make more cases go to state court. Now, lawsuits often claim accounting problems or insider trading, instead of just making false predictions. Before the law, stock prices dropped by 19% before a lawsuit, but now they drop by 31%. Tech companies are sued the most, and a big law firm called Milberg Weiss is involved in more cases. Overall, the law seems to have changed how these lawsuits work, but it's too early to say if it's working well or not.
