For the past two days, the stock market has tumbled after a string of record rallies driven by Facebook, Apple, Amazon, Tesla, and other tech companies. While some are speculating about what is causing the tech selloff, others are rationalizing it as the market returning to “normal.” The market’s not normal, however. 

Yesterday, Apple, which saw a strong surge after its Monday morning stock split, lost $180 billion in a single day. As Barron’s noted, this is the most money that any company in history has lost in one day, which is a gobsmacking fact on its own. Now, consider this: even after losing the most money in one day ever, Apple still had a valuation well above $2 trillion, a truly unfathomable amount of money. And despite that massive loss, the company's stock was still up 65 percent at market close from January 2020 and up 127 percent from that time last year.
