There's nothing like sitting by the pool and enjoying some pizza, and Warren Buffett just bought himself a slice of both.

Buffett, chairman and chief executive of Berkshire Hathaway (BRK.A) , has always had a fondness for brands.

"A strong brand is really potent stuff," the Oracle of Omaha has been known to say.

When it comes to investing, Buffett likes to get medieval in that he believes in the economic moat theory.

“A truly great business must have an enduring 'moat' that protects excellent returns on invested capital,” the legendary investor said. "Brands are moats."

Just like the moats that encircled the castles of yesteryear, economic moats are intended to protect businesses from the rampaging hordes of competition.

But you have to build your moat property, because — heads up, another Buffett quote coming — "a moat that must be continuously rebuilt will eventually be no moat at all."

"Warren doesn’t outperform other investors because he computes odds better," Microsoft (MSFT) Co-Founder Bill Gates wrote in the Harvard Business Review in 1996. "That’s not it at all. Warren never makes an investment where the difference between doing it and not doing it relies on the second digit of computation."

DPZ and POOL shares rise on Buffett purchases

"He doesn’t invest — take a swing of the bat — unless the opportunity appears unbelievably good," Gates said.

Apparently Buffett sees an unbelievably good opportunity in Domino's Pizza (DPZ) and Pool Corp. (POOL) , according to a recent filing with the Securities and Exchange Commission.

Berkshire bought 1.28 million shares of the global pizza delivery chain, which were valued at $550 million at the end of the third quarter. And he added more than 400,000 shares of the wholesale distributor of pool equipment.

Shares of both companies jumped on news of Buffett's investments.

Domino's stock has risen 8,5% year-to-date and 20% from a year earlier. Pool Corp., on the other hand, is down 9% year-to-date and has advanced 3.5% from this time last year.

And both companies recently posted quarterly earnings.

Domino's, Ann Arbor, Mich., the largest pizza chain in the U.S., last month reported mixed third-quarter results, beating Wall Street's expectations for earnings but falling short on revenue.

Same-store sales in the U.S. increased 3%, missing analysts' consensus estimate of 3.55% and coming in below the 4.8% reported a year earlier.
