The most widely watched tech stocks saw their collective market value drop by $141 billion on Tuesday amid a broader market sell-off.

That amount is about equal to the market capitalization of McDonald's.

The biggest loser among the tech giants was Amazon, which lost $51 billion in market value.

You could just about buy McDonald's with the amount of value the most widely watched tech stocks shed on Tuesday.

If you include Microsoft's market losses, you could snap up Burger King's owner as well — or a heck of a lot of Big Macs and Whoppers.

On a down day for the markets, the big tech stocks got crushed. Collectively, Facebook, Apple, Amazon, Netflix, and Google parent company Alphabet, lost $141 billion in market value, as their stocks declined 4.5% on average.

Microsoft, which has been vying with Apple for the title of most valuable public company in the world, saw its shares fall 3%, as the company's market capitalization dropped $27 billion.

By comparison, McDonald's has a market value of $143 billion and Restaurant Brands International, the parent company of Burger King, has a market value of $26 billion.

Amazon was the biggest loser

Among the big tech shares, Amazon was the biggest loser. With its stock falling nearly 6% to $1,668.40, the e-commerce giant's market capitalization plunged $51 billion. That's about the same amount that General Motors is worth in total.

Apple was the next biggest loser, at least in terms of the market value it lost. The iPhone maker saw its capitalization drop $39 billion thanks to its stock falling 4% to $176.69.

In terms of percentage declines, Netflix was second to Amazon. Its stock fell 5% to $275.33, resulting in a drop in its valuation of $6.5 billion.

The sell-off in shares of the big tech companies has been going on for months amid broader concerns about slowing growth and stricter regulations. Although Facebook only saw its shares and market valuation drop by 2% Tuesday, its stock has declined the most from its peak this year of any of its peers. Since hitting their apex in July, Facebook's shares are down nearly 37% at $137.93.

Netflix is a close second in that category. Its shares are down 35% since they peaked in June.

Tuesday's decline in tech shares extended far beyond the giants, with the tech-heavy Nasdaq Composite index falling 3.8% to $7,158.43.

Intel's shares fell by 5% to $47.75. Western Digital, Micron, and Nvidia all saw their shares drop by more than 7% to $43.04, $36.88, and $157.11, respectively. E-Trade declined by 8% to $48.65. And AMD shares fell by a whopping 11% to $21.12.
