The last-minute pounding Wall Street gave Google's shares was caused by "erroneous orders" that Nasdaq says it is canceling.
Minutes before the closing bell Tuesday, a flurry of trades sent the Web search leader's stock plummeting 10 percent to close at $341.43.
Nasdaq said in a statement that erroneous orders routed to Nasdaq from another market center were responsible for the high volume of trades.
The exchange raised Google's closing price to $400.52 — a 5 percent gain for the day — and canceled all trades below that amount and above $425.29 between 3:57 p.m. and 4:02 p.m. EDT.
