The coronavirus pandemic has whiplashed global markets this year, sending stocks on a rollercoaster ride as the world rushed to contain the spread of COVID-19.

The market meltdown that bottomed on March 23 erased trillions from US stocks, swiftly ending the longest-ever bull market and dashing nearly all gains made since President Trump took office. In addition to the market rout, extreme volatility whipped through indexes in March, setting off a number of circuit breakers sometimes more than once a day.

Since the recent lows, however, US stocks have rebounded, even amid devastating economic data showing the fallout from coronavirus-induced lockdowns.

The S&P 500 has gained roughly 36% from March 23 through Wednesday's close, and is now only about 12% from its all-time high hit on February 19. The Dow Jones industrial average is up more than 37% from its March low, and is 15% below its February high.

The rebound rally has been led by technology stocks, which many investors see as poised to outperform both amid the pandemic and through a recession. The tech-heavy Nasdaq in early May erased all year-to-date losses as strong tech earnings and investor confidence fueled a rally. In addition, much of the indexes' gains are tied to Facebook , Apple , Amazon , Microsoft , and Alphabet, which make up 38% of the composite.
