10. Wells Fargo

The loss: $28.9 billion

Wells Fargo took a beating on Wall Street the day the Federal Reserve put the banking giant on a tight leash.

Following a series of scandals at Wells Fargo, the Fed announced tough penalties including limits on the company's ability to grow.

The bank had admitted its employees created up to 3.5 million unauthorized accounts for customers. Also, Wells Fargo auto loan borrowers had been sold insurance they didn't need, and other customers paid inappropriate mortgage fees.

9. Amazon

The day: April 2, 2018

The loss: $36.5 billion

Amazon's stock had a blue Monday after President Donald Trump made the online retailer one of his prime targets on Twitter.

He had complained in weekend tweets that the U.S. Postal Service was losing money on Amazon deliveries.

Fact-checkers disputed that claim. Some observers speculated that Trump was picking on Amazon because he didn't like his coverage in The Washington Post, owned by Amazon CEO Jeff Bezos.

8. Bank of America

The loss: $38.5 billion

Bank of America got hammered on the stock market when the company announced surprisingly awful financial results in the midst of the 2008 financial crisis.

The banking powerhouse reported that its quarterly profits were down a stunning 68% from a year earlier — much worse than Wall Street analysts were expecting.

BofA also broke it to investors that their dividends were being reduced by half.

7. Alphabet

The day: Feb. 2, 2018

The loss: $41.1 billion

It was no red-letter day for investors in Google's parent company when Alphabet's earnings fell short of analysts' forecasts.

The disappointing numbers spelled a 5.3% drop in the company's stock price.

But Alphabet gets an "A" for a nice recovery. The stock has rebounded more than 25% from its 2018 lows and recently hit a one-year high.

6. General Electric

The day: April 11, 2008

The loss: $46.9 billion

General Electric gave Wall Street a shock, and its stock went dim.

The company's stock got punished after GE reported a 6% drop in profits, something investors and analysts didn't see coming.

The conglomerate had gotten caught up in the 2008 financial meltdown. Profits in its financial services business had taken a painful 20% hit.

5. Exxon Mobil

The day: Oct. 15, 2008

The loss: $52.5 billion

The fall of 2008 took a toll on all kinds of industries, not just banks and lenders. Energy giant Exxon Mobil hit a bad oil slick on Wall Street at a time when it was the world's largest company.

That happened on a rough day for stocks overall: The Dow Jones industrial average plunged 733 points, its second-biggest one-day point drop.

But oil stocks got squeezed by a dip in crude oil prices and worries that a recession would lead consumers to buy less gasoline.

4. Apple

The day: Jan. 24, 2013

The loss: $59.6 billion

The iPhone was expected to be a huge holiday season hit in 2012, but sales weren't quite as big as expected.

That was the news from Apple in late January 2013 that caused the company's stock to crater.

Some analysts responded by predicting the beginning of the end of Apple's smartphone — but more than five years later, strong iPhone sales are pushing Apple's profits and stock price to new highs.

3. Microsoft

The day: April 3, 2000

The loss: $80.0 billion

Microsoft had its worst day ever when a federal judge ruled that the software company was being a bully and using its dominance with Windows to hurt competitors in the computer business.

The wipeout for Microsoft's stock cost co-founder and then-chairman Bill Gates $11 billion, at least on paper.

2. Intel

The day: Sept. 22, 2000

The loss: $90.7 billion

Wall Street rebooted computer chip maker Intel after the company got slimed by the bursting of the dot-com bubble.

Intel warned in September 2000 that it was seeing weaker demand for its chips in Europe, and that its overall sales were sluggish.

The stock took a 22% nosedive.

1. Facebook

The day: July 26, 2018

The loss: $119.4 billion

Facebook tops this ranking for a day on Wall Street when it lost a ton of friends — and money.

The company's stock price crashed, costing CEO Mark Zuckerberg more than $15 billion.

This was after investors and analysts found a lot not to like in the social network's profit report for the second quarter of 2018. The results suggested to some that Facebook may have seen its best days.
