The analysis of the Galleon Group case study reveals that insider trading activities are illegal and unethical, resulting in unequal dissemination of information about a stock to market participants. The occurrence of such activities can cause huge losses to other investors and lead to personal gains for those involved. Although regulatory measures, such as civil penalties and punishments, have been implemented to deter insider trading, they cannot completely eliminate the problem. As a result, there is a need for continuous monitoring of daily stock market activities and the development of innovative techniques for identifying insider trading.
