Common wisdom suggests America’s most famous investor has long avoided high-tech companies.

Instead, Warren Buffett has stuck to what he knows – everything from insurance and railroads to soda and razors.

“I know about as much about semiconductors or integrated circuits as I do of the mating habits of the [beetle],” Buffett once wrote. “We will not go into businesses where technology which is way over my head is crucial to the investment decision.”

He felt technology lacked margin of safety, and many “Buffett-heads” followed his lead – and they all missed out on tech stocks’ leaps in value over the last eight years or so.

But that’s not the only reason that common wisdom isn’t looking so wise anymore…

As we’ve been saying here for a while now, every business has become a tech business. It’s all because of the Convergence Economy, where we see multiple technologies merging into new, innovation-unlocking and profit-making creations. That leads to everything from cloud computing and the Internet of Everything to smart homes and connected cars – to technology affecting every part of our daily lives.

But you don’t have to take my word for it…

Fact is, Buffett has been getting to know tech – and he’s been quietly moving into technology stocks over the last six years. He just doubled his holdings in Silicon Valley legend Apple Inc. (Nasdaq: AAPL).

This may sound like merely trivia – after all, we’ve never let Buffett’s aversion to tech stop us.

But I believe the Oracle of Omaha’s move into tech is far more important that it might sound at first.

So today we’ll investigate why Buffett’s newfound interest in smartphones and semiconductors are crucial to our understanding of the tech sector.

Then, we’ll dig up a cost-effective way to play this unstoppable trend that will make you plenty of money in the years to come.
