Last month, the hedge fund teamed up with Firebrand to launch an activist campaign to likely challenge the company's board. Together the two had a joint 4.9% stake in the company at the time, but earlier this month, the activists upped their combined stake in the New York-based publisher to 9.96% and officially nominated four directors to the Times' 13-member board. The most recent purchase was made between Feb. 11 and Feb. 15 at roughly $16.97 to $18.71 per share. - Michael Rudnick
