Worried We're in Another Dot-Com Crash? Here's the Biggest Mistake to Avoid.
Between March 2000 and October 2007, the S&P 500 Index (SNPINDEX: ^GSPC) increased by a rather paltry 1.43%. To compound that painful six-and-a-half-year period, the S&P would fall more than 55% from the 2007 high during the Great Recession.
Combined, the world's most notable stock index -- a collection of 500 of the most-valuable and important public companies on earth -- would lose more than half its value in the "lost decade" between March 2000 and March 2009. The tech-heavy Nasdaq Composite (NASDAQINDEX: ^IXIC) would lose nearly three-fourths of its value over the same period.
The S&P would take another four years to return to the highs it reached in 2000, while the Nasdaq didn't fully recover until March of 2015. That's 12 and 15 years respectively for these two indices to fully recover.
