McGruber writes "In a blog entry, American business magnate Mark Cuban explained who he blames for his losing money in Facebook stock: 'I bought and sold FB shares as a TRADE, not an investment. I lost money. When the stock didn't bounce as I thought/hoped it would, I realized I was wrong and got out. It wasn't the fault of the FB CFO that I lost money. It was my fault. I know that no one sells me shares of stock because they expect the price of the stock to go up. So someone saw me coming and they sold me the stock. That is the way the stock market works. When you sit at the trading terminal you look for the sucker. When you don't see one, it's you. In this case it was me.'"
