Through the prism of The Good, the Bad and the Ugly on Wall Street, here's Warren Buffett off the cuff Thursday.
With the yield on the 10-year Treasury at around 2.42 percent Thursday, billionaire investor Warren Buffett told CNBC he's not going to "start salivating" over that kind of return.
Buffett said on "Squawk Box " that he'd take stocks over bonds because he knows he's going to do better.
With less than four years left, Buffett has a commanding lead in a decade-long bet that put a low-fee stock index fund up against a portfolio of high-priced hedge funds. Buffett told CNBC Thursday: "I'm quite aways ahead on that bet now."
Buffett said he regrets his investment in U.K. supermarket operator Tesco. He'd lost over $700 million, as of last month, with Tesco shares down about 45 percent this year. "That was a huge mistake by me," he admitted.
