Nasdaq Composite Closes Above 5,000 For Second Time Since 2000

U.S. stocks rebounded Friday, with the Nasdaq composite closing above 5,000 for only the second time since the dot-com bubble in 2000, as investors cheered strong earnings and a boost in oil prices. Friday also saw an increase in trading volume due to "quadruple witching," or the expiration of stock options that occurs on the third Friday at the end of every quarter, in March, June, September and December.
