Warren Buffett's Berkshire Hathaway reveals new bets on Domino's Pizza and Pool Corp.

Warren Buffett's Berkshire Hathaway took a bite of the pizza business and jumped into the swimming pool industry last quarter.

Warren Buffett's Berkshire Hathaway purchased stakes in Domino's Pizza and Pool Corp. last quarter.

 The investing legend's company made big cuts to its huge Apple and Bank of America positions.

Berkshire pared other holdings such as Capital One, and sold almost all of its Ulta Beauty shares.

The famed investors conglomerate bougnt a slice of Domino's Pizza worth $549 million at the end of September, a portfolio update revealed Thursday. Its nearly 1.3 million shares represent a 3.7% stake in the pizza-delivery company.

Buffett and his team also purchased just over 1% of Pool Corp. - a wholesale distributor of swimming pool supplies and related products. That position was worth $152 million at the quarter's close.

Both bets are small relative to Berkshire's vast US stock portfolio, worth $266 billion on September 30. But neither was public knowledge prior to the filing's release, unlike the cuts that Berkshire made to its key Apple and Bank of America stakes. Those were broken out in its recent third-quarter earnings and fueled its net $35 billion of stock sales in this period 

Buffett owning a piece of Domino's Pizza seems fitting given his insatiable appetite for fast food and the companies that produce it such as Berkshire-owned Dairy Queen.

The 94-year-old CEO and his two investment managers, Todd Combs and Ted Weschler, jettisoned a net $127 billion of stocks in the first nine months of this year, inflating Berkshire's cash pile to record highs of more than $300 billion last quarter.
