Trouble for TD Ameritrade; Greek Deal Hopes Trigger Stock Rally

TD Ameritrade (AMTD) was in hot water Friday after its trading platform experienced difficulties executing orders. This is the latest in a string of tech failures this week. On Wednesday, the New York Stock Exchange went dark for nearly four hours and United Airlines (UAL) grounded flights for an hour due to a tech malfunction. Stocks moved confidently higher, boosted by the growing likelihood of a solution to Greece's debt drama. The S&P 500 and Dow turned positive for the month after Athens submitted proposed spending cuts for European creditors to review. Gap (GPS) was lower after reporting a 1% decline in same-store sales in June. Analysts expected sales to decline at half that pace.
