The Nasdaq 100 index, which tracks the 100-largest nonfinancial companies in the Nasdaq Composite, rose 0.5% to close 0.3% below a record set on Feb. 19. The index has rallied more than 43% from an intraday low set on March 23. Those gains have been provided in large part by stocks that benefited from people staying at home due to the coronavirus. The Invesco QQQ Trust — which tracks the Nasdaq 100 — closed 0.5% higher.

Data compiled by LPL Financial showed the S&P 500 was experiencing its largest 50-day rally in history. The data also showed stocks were higher 100% of the time six and 12 months after the previous largest rallies on record.

For stocks, a fall of 20% from the peaks would mark the end of the bull market and meet the widely used definition of a bear market. For the S&P 500 that would require a close at or below 2,708.92, while the Dow would need to end at or below 23,641.14, according to Dow Jones Market Data. The bear-market threshold for the Nasdaq stands at 7,853.74.

The current correction is hardly the first nor, so far, the deepest of this bull market. Pullbacks in 2011 and late 2018 saw the S&P 500 retreat more than 19% from its previous highs, putting the index within a whisker of ending the bull run, before recovering to push to new heights.
