Anyone who is not living in the cave knows the market crashed today for a few minutes and then went back up. The crash was caused by a huge crash in Proctor and Gamble's(PG) price(24% drop). No one knows what caused the stock to tumble but it caused the whole market to tumble. It might have been a computer crash or it might have been a large short sale by a massive hedge fund or bank. Only time will tell.
I do not normally quote Jim Cramer but he had a great call on PG. Here is Jim Cramer discussing the crash today as it occurred. Watch the video I do not feel the need to add more commentary. Kudos to Cramer.
