(Reuters) - Warren Buffett's Berkshire Hathaway ( BRK/A ) said on Thursday it made new investments in Domino's Pizza and Pool Corp ( POOL ) in the third quarter, even as it retrenched from from stocks such as Apple ( AAPL ) and Bank of America ( BAC ).

Berkshire owned 1.28 million Domino shares worth about $549 million as of Sept. 30. It also owned 404,000 shares of Pool, a distributor of swimming pool supplies, worth about $152 million as of that date.

The investments were disclosed in a U.S. Securities and Exchange Commission filing detailing Berkshire's U.S.-listed investments as of Sept. 30.

Shares often rise after Berkshire discloses new investments, reflecting investors' belief that Buffett may be providing a seal of approval.

Thursday's filing does not say whether Buffett or his portfolio managers Todd Combs and Ted Weschler are responsible for individual investments.
