Key Takeaways Domino’s Pizza shares jumped nearly 8% in extended trading on Thursday after a filing revealed that Warren Buffett’s Berkshire Hathaway had taken a stake in the world’s largest pizza chain.

Domino’s is the only sizable new equity holding by Berkshire in the period. Domino’s shares are rising in after-market activity in an apparent reaction to the Berkshire news.

Berkshire Hathaway Inc. bought stock in Domino’s Pizza Inc. and Pool Corp. during the third quarter as Chairman Warren Buffett cut back on some long-held investments. Shares of the two new holdings jumped in late New York trading.
