Buy It Like Buffett

If you had invested $10,000 in Warren Buffett's Berkshire Hathaway back in 1965, your stake would be worth a cool $31 million today.

The investment community is populated by plenty of Buffett disciples, but the Oracle Of Omaha also has his share of disbelievers.

First, the fans.

"I've tried to find a better philosophy, and I really haven't, after 25 years," Jeff Auxier of Auxier Asset Management told CNBC.

Now, the flip side.

"Berkshire Hathaway stock is overvalued," Mark Hake of Hake Capital Management said. "There's very little disclosure in his annual report, and then, there's some technical issues."

Hake admits that popular opinion may not be on his side, and he blames that attitude for the over-valuation he perceives.

"Everyone thinks he's such a great guru," Hake said.

CNBC Contributor Herb Greenberg thinks trading like Buffett is all in the timing.

"If I knew I could buy when he was buying, and sell when he was selling, then I would do it," he said. "Riding the coattails of any investor has its perils."
