Apple just became the first publicly traded U.S. company to be valued at a whopping $3 trillion. AAPL stock topped out at $182.88 a share Monday before dropping slightly, bringing the market cap back below the $3 trillion milestone.

It closed at $182.01, leaving Apple’s market cap at an astonishing $2.99 trillion. But it continued to climb once again in after-hours trading.

A sharp rise in Apple’s share price allowed the Mac-maker to regain the title of publicly traded company with the highest market capitalization n the world. It beat out Microsoft, who’d held the top spot for less than a month.

An unconfirmed report of Apple’s aggressive plans to make self-driving cars helped drive a 6% increase over the past week.

Apple’s stock is tanking in after-hours trading, despite the company’s announcement of yet another record-breaking quarter. The problem? Wall Street expected it to make way more.

Apple made more money in the last year than any other company in the world, according to the new Fortune 500 rankings. With annual profits of $57.5 billion, no other enterprise came particularly close, with the nearest rival earning about $8 billion less.

This goes a long way toward explaining why Apple remains the most valuable publicly-traded company in the world.

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.

Apple is the world’s most valuable public company, days from unveiling new software and hardware at WWDC, in the middle of its hottest iPhone cycle in years, and having just debuted its biggest iMac redesign in years. So all is good, then?

Well, apparently not. In fact, a report Friday notes that Apple stock is currently on track for its longest weekly losing streak in more than two-and-a-half years. Because the stock market works in mysterious ways.

Update: AAPL closed at $125.89 Friday, up $2.35 (or 1.9%). So much for the losing streak.

Apple shares spent much of Tuesday down 4% in value. The AAPL selloff was part part of a general drop in tech stocks amidst fears of a rise in interest rates.

At one point during the day, the value of each AAPL stock had dropped about $5.30. That’s a decrease of roughly $88 billion in Apple’s $2.1 trillion market capitalization.

Update: Apple shares finished the day down 3.54%.

Apple’s market cap has climbed more than $13 billion this year alone, equal to the company’s entire net worth in mid-2004. But that’s still enough to make it an underperformer next to its tech titan peers.

In a Wednesday report, the Wall Street Journal notes that Apple has risen 1.3% in 2021 so far. That’s compared to an average of 16% for Microsoft, Amazon, Facebook, and Google parent company Alphabet. It’s also way less than the 81% Apple soared in 2020.

Apple’s valuation roars past $200 billion as a result of intense excitement over the first-generation iPad. Things look good for the company as it guns for powerhouses ExxonMobil and Microsoft.

Apple’s annual shareholders meeting won’t take place on the Apple Park campus this year as it ordinarily would. With the COVID-19 pandemic dragging on, it’ll be a virtual-only event in 2021. This is likely to increase participation in the February 23 meeting. And if you own AAPL shares, you can attend.

Here’s what you need to do.
