how.much did the stock.market drop when the dot.com bubble burst

The Nasdaq fell about 78% from its March 2000 peak to its October 2002 low during the dot-com bust. Other summaries put the decline at roughly 75% , but the commonly cited figure for the tech-heavy index is 78%.

What that means

• The Nasdaq peaked at around 5,048 in March 2000 and bottomed near 1,139 in October 2002.

• That collapse erased roughly $5 trillion in market value, according to several historical accounts.

• The broader lesson is that the crash hit tech and internet stocks far harder than the overall market.

Quick context

The dot-com bubble was driven by speculation in internet companies, many of which had weak or no profits. When investor confidence broke, the selling accelerated and the index kept falling for more than two years.

TL;DR: about 78% for the Nasdaq from peak to trough.
