I am quoted in this article:
“Most portfolio managers would be considered successful when they are right 70% of the time. Warren Buffet is right 90% of the time,” said David Kass, a finance professor at the University of Maryland and the author of a blog on Buffett and Berkshire Hathaway.
“This is what differentiates him.”
“He is a plain vanilla investor,” Kass said. “He does not use exotic financial instruments, he does not borrow too much.”
Despite all these hits, a critic could find fault with Buffett for missing the boat on a host of technology giants, including Amazon, Facebook and Google.
“He does not have an expertise there,” explained Kass. “He does not see any reason he could outperform the market.”
