SOLD 45 shares of SNDK @ 50.01

I finally sold the SNDK shares just right before the earning release, it represents 5.28% return in period of 2 days. I'm just worried that the stock price will shoot down if the earning is lower than expected since there are so much hope on this company by investors. I read about news on how NAND chip is oversupplied and recently SMOD also report a lower than expectation earning due to the very same reason. I don't want to see the stock price goes down like eBay had today. So I take what I can get for now :)
