The activist hedge fund investor joins his peers in holding shares of the tech giant.

NEW YORK (TheStreet) -- While hedge funds jumped over one another during the fourth quarter to buy Apple(:AAPL) shares, not all of them disclosed it right away.

First reported by Zero Hedge, Third Point's Daniel Loeb disclosed a position in the Cupertino, Calif.-based company in his February shareholder letter. The holding wasn't revealed in his 13F filing as of the end of 2011.

Loeb, who was known as Mr. Pink on The Silicon Investor stock message boards, has been spending most of his time battling Yahoo!(:YHOO), as he tries to unlock shareholder value in the company.

The Loeb letter didn't say how many Apple shares Third Point owns. Rounding out the top five positions in Loeb's $8.9 billion portfolio are Eksportfinans ASA, a Norwegian financing company, Delphi Automotive(:DLPH), an auto-manufacturing company, and gold.

Shares of Apple are up 0.1% to $545.06 today.
