An analysis by the SEC Commissioner found that executives frequently exploit stock buybacks to cash out their company shares at inflated prices.

“Even more disturbing, there is clear evidence that a substantial number of corporate executives today use buybacks as a chance to cash out the shares of the company they received as executive pay. We give stock to corporate managers to convince them to create the kind of long-term value that benefits American companies and the workers and communities they serve. Instead, what we are seeing is that executives are using buybacks as a chance to cash out their compensation at investor expense…Executives often claim that a buyback is the right long-term strategy for the company, and they’re not always wrong. But if that’s the case, they should want to hold the stock over the long run, not cash it out once a buyback is announced.”
