Bought 10 shares of GOOG at $545

Yahoo! just reported a result today and their profit falls as Google gains market share. I bought 10 shares in the after market for $545. The 10 days technical indicator showing that it should go up. Moreover, Google will have earning report on January 31. I'm still deciding whether I should hold it through the earning or selling it right before it. At this volatile market, I don't know what I need to do but we'll just see how Google stock react tomorrow.
