What a crazy day it was for the Dow Jones Industrial Average (INDEX: ^DJI), which crawled nearly all the way back to even today after dropping more than 190 points in early trading. Europe was the main catalyst for the drop early in the day, as investors continued to worry about the possibility of Greece's exit from the eurozone. But the day turned around late as optimism reigned that the Greece fears were overblown, and more positive U.S. housing data was digested. Individually, Bank of America (NYSE: BAC) was the biggest winner on the day, while Intel (NYSE: INTC) and Microsoft were dragged down by Dell's poor earnings and concern about demand for PCs. Outside the Dow, Facebook (Nasdaq: FB) finally had a positive day, gaining 3.2%, but is still down 23.9% since its IPO on Friday.
