Warren Buffett is one of the greatest financial masterminds of our time. But he’s not infallible. Sometimes even Warren makes mistakes — and one of those recent mistakes was called Apple.

Buffett’s Berkshire Hathaway firm has long invested in Apple, with Buffett once saying that, “I don’t think of Apple as a stock. I think of it as our third business. It’s probably the best business I know in the world. And that is a bigger commitment than we have in any business except insurance and the railroad.”

Apple has done extremely well for Buffett. The company’s stake in Apple has tripled in value in the past three years. On Wednesday, as Apple closed at a new all-time high, it was worth $128 billion. It accounts for more than 40% of Berkshire’s US portfolio, while Berkshire is Apple’s second larger shareholder (after index fund giant Vanguard.) However, Buffett has also been pruning his Apple stake. And it’s cost him.

Berkshire Hathaway — the investment firm belonging to Warren Buffett, one of Apple’s biggest cheerleaders in recent years — reduced its stake in the Cupertino tech giant last quarter.

According to a regulatory filing made this week, in Q4 2020, Berkshire Hathaway cut 6% of its Apple shares. By contrast it kept its Amazon shares steady, while growing its stake in T-Mobile by a massive 117%.

Warren Buffett, the legendary investor and big-time Apple booster, now has a share of the company worth upward of $100 billion.

Even more impressive? Buffett’s firm Berkshire Hathaway reportedly spent on around $35 billion to secure its 5.7% stake in Apple. That’s a pretty darn great return on investment — and Apple’s only climbing higher.

A decade ago, Berkshire Hathaway founder Warren Buffett said he just didn’t get Apple. Today, Apple shares make up some 43% of Berkshire Hathaway’s entire stock portfolio, according to a report from Motley Fool.

The firm’s 245 million Apple shares have increased in value by more than $55 billion since the start of 2019 to be worth upward of $91 billion. Still, from an investor’s perspective, it makes you wonder whether you’d be better off simply investing in AAPL itself, rather than paying a fund manager!

Warren Buffett may be one of the shrewdest financial minds of our time, but don’t expect him to be able to use an iPhone. Despite receiving a personal lesson from Apple CEO Tim Cook.

“I went out to California, and Tim Cook very patiently spent hours trying to move me up to the level of the average two-year-old,” Buffett told Yahoo Finance editor-in-chief Andy Serwer. “And didn’t quite make it.”

Despite selling off nearly $1 billion worth of Apple shares earlier this month, Berkshire Hathaway CEO Warren Buffett is still bullish on the iPhone-maker.

Warren told CNBC he wishes he bought Apple shares before he did. Buffett is so hyped on Apple he finally ditched his old flip phone and bought an iPhone.

Warren Buffett’s investment firm Berkshire Hathaway sold more than $800 million of Apple stock in the last quarter of 2019.

Buffett is probably Apple’s most famous investor and cheerleader. Berkshire Hathaway is the Cupertino tech giant’s biggest shareholder, with an estimated 5.4% stake in the company.

Apple CEO Tim Cook sounded absolutely ecstatic to count Warren Buffett as one of his company’s investors during an interview at Berkshire Hathaway’s shareholders meeting this morning.

Cook made a cameo in the company’s opening video — that also introduced Apple’s new Buffett-themed game — and sat down with CNBC to talk about his relationship with Warren, Apple’s culture, privacy and more.

Apple has finally come out with its first new video game for iPhone since the App Store debuted in 2008 and its dedicated to the iPhone-maker’s largest shareholder, Warren Buffett.

Tim Cook made a cameo appearance at Berkshire Hathaway’s shareholder this morning to reveal the new game. The game, called Warren Buffett’s Paper Wizard, sounded like a joke at first. Players cruise around tossing newspapers at houses as an homage to Buffett who had a paper route as a kid to make money. Now he’s one of the richest men in the world with his own paperboi video game to boot.

Mega-investor Warren Buffett says that Apple’s most recent earnings confirm “the reason [my firms owns] $50 billion-plus of Apple.”

Speaking on CNBC, the Berkshire Hathaway investor said that, “I was pleased with what they reported.”
