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 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 played a part in a historical and brutal day on Wall Street Thursday as fears and concerns over the coronavirus accelerate. The Dow 30 plummeted 10% in value as Apple stock lost almost the same.
