After Tuesday's last minute collapse, investors on Wednesday had to wait until the closing bell to see if a market rally could hold. (Tweet this.)
And a rally it was. The Dow Jones industrial average closed up more than 600 points to end at 16,285.51. The last time the index closed up over 500 points was back in November 2008.
The S&P 500 also came out of a correction from its May high when it ended up 3.9 percent.
