Ryan Cohen bought $17 million in shares of GameStop on Oct. 2 to increase his personal ownership in the company. The chief executive also purchased $10.6 million of the video game retailer's stock on Sept. 30, continuing a period of consistent insider acquisitions over the previous month.

The recent trades bring Cohen's total year to date stock purchases to nearly $100 million. This buying spree included acquisitions of $26 million and $20 million in late September, though the total amount spent remains a small fraction of his overall net worth.
