The Dow Jones Industrial Average [: DJIA] was down 600 points, or 2%, at 29,990, the S&P 500 index
was off 2.1% at 3,709, while the Nasdaq Composite Index [: COMP] was 2.2% lower Friday. GameStop shares
were up 70% on Friday after trading app Robinhood said it would allow limited purchases of the stock. Robinhood restricted trading Thursday of GameStop, AMC
