Warren Buffett admitted to shareholders Saturday that he made a mistake by not buying Google shares years
The Oracle of Omaha also professed ignorance on other big technology stocks, whose rallies he missed because he didn't quite appreciate their value proposition at first glance.
On CNBC's "Squawk Box" on Monday, Buffett said, "If I was forced to buy [Google-parent Alphabet] or short it, I'd buy it; same way with Amazon. But it's as little hard when you look at something at 'X' and it sells at 10X to buy it."
"That's cost people a lot of money at Berkshire," he said.
