Gundlach on stocks: Tesla can 'ultimately change society'

DoubleLine CEO Jeffrey Gundlach made his name as a bond expert, but he's still got plenty to say about certain stocks.

In an interview with CNBC on Monday, Gundlach gave his thoughts on three of Wall Street's biggest names—Apple, Tesla Motors and Amazon. The bond investor was particularly bullish on Tesla, and not because of its electric cars.

Gundlach said the company's batteries could "change society" when coupled with one of Tesla founder Elon Musk's other ventures—solar power.

"I like Tesla," Gundlach said on "Squawk Alley." "It's the batteries. It's all about the batteries. I think they can ultimately change society if they pursue battery technology that really creates the ability to store enough energy that you could, say, run a house on, get yourself off the grid."

During a CNBC interview in September, Gundlach had recommended selling Apple. But the stock went on a more than 20 percent run since then.

On Monday, Gundlach seemed unfazed. He said he bought Apple at a discount compared to its new highs. Selling at near record levels would not be "a roadmap to the poor house," he added. As far as buying now, however, Gundlach said he doesn't like to buy stocks pushing all-time highs.

With Amazon, Gundlach said he's been "mystified" by the stock. He said the rest of Wall Street has come around to his thinking on the e-commerce behemoth—that the company needs to start turning profits on a regular basis.

"The market has kind of given up on Amazon," Gundlach said.
