Warren Buffett's Berkshire Hathaway bet on Domino's Pizza and Pool Corp. last quarter, and both stocks fit well in its portfolio.

Berkshire Hathaway initiated these new positions during the third quarter even as it cut back its holdings of big names like Apple and Bank of America.

Berkshire bought 1.3 million shares of Domino's, giving Buffett a 3.6% stake in the pizza retailer that's valued at $550 million U.S. Buffett's company has also taken a 1% stake in pool equipment wholesale distributor Pool Corp. that's valued at $152 million U.S.
