1. The author of the article does not clearly define what a stock buyback is and how it works. This leaves the reader confused about the concept and its implications for investors. A better introduction would explain that a stock buyback is a corporate action where a company uses its cash or debt to purchase its own shares from the market, reducing the number of outstanding shares and increasing the ownership percentage of existing shareholders. The author should also mention some possible reasons why companies engage in buybacks, such as improving financial metrics, signaling confidence, returning excess cash to shareholders, or offsetting dilution from stock-based compensation.
