Warren Buffett has taken the investment community on quite an adventure in recent years regarding his relationship with technology stocks.

As recently as five years ago, a full eight years after the launch of the iPhone, the "Oracle of Omaha" remained dubious of Apple shares and technology shares in general, refusing to put them in his portfolio because he considered them too risky and hard to understand.

“I know about as much about semiconductors or integrated circuits as I do of the mating habits of the chrzaszcz (beetles),” he was famously quoted as saying in regards to tech stocks.

In early 2016, however, Buffett surprised analysts, investors and skeptics who openly wondered if he was losing his touch by purchasing 10 million shares of Apple stock.

A few years later, in a CNBC interview, Buffett explained that he no longer viewed Apple as a hard-to-understand technology company.

“I mean it’s an amazing business,” Buffett told CNBC. “You can put all of their products on a dining room table.”

Earlier this month, it was reported that Buffett's Berkshire Hathaway has seen its stake in Apple triple in value, to more than $100 billion. Buffett, the former technophobe, recently called Apple “probably the best business I know in the world.”

There's a simple reason why Buffett's view on Apple stock was so closely watched: People like to mimic the actions famous investors.
