- Warren Buffett summed up why he's not buying Amazon shares in one word.
- The billionaire investor praised the e-commerce giant's founder Jeff Bezos for executing on big ideas.
- At Berkshire Hathaway's shareholders meeting on Saturday, Buffett said he missed an opportunity by not buying Google or Amazon shares.
"Stupidity," Buffett said during an interview Monday on CNBC's "Squawk Box."
"I was impressed with Jeff early. I never expected he could pull off what he did ... on the scale that it happened," Buffett said Monday. "At the same time he's shaking up the whole retail world, he's also shaking up the IT world simultaneously."
"These are powerful, powerful ideas with big potential, and he's executed," Buffett said.
