It wasn't an error. Proctor & Gamble starting to sell heavy which in turn caused the market to stop trading. P&G then continued to sell through online brokerage house at a tremendous loss of $20-30/per share. By the end of the day, P&G almost caught up with where it should have been. The news reported that it all started in Europe, where Greece is having huge financial trouble. It looks like tomorrow will be another roller coaster day, and this will not help the US one bit. It looks like this whole planet is owing each other tons of money and can't pay it when the bill comes in on their loan. Looks like still another long road ahead for everyone worldwide.
I think I am going to invest in some liquor companies, they always seem to do well in crisis times :P
Just remembered, I can't invest, I have no money
