Give up trading. You obviously are bad at it. Good traders never panic. Or, if you insist on doing it try trading with a small number of shares so that if you make a bad trade it is not so financially devastating for you.
Even the news about FB join Nasdaq-100 just announced , the price could have blend in a little, but , still , there are so many funds in the world , they need to include the FB in their portfolio(s) , I don't really want to tell you what to do , for next few weeks before new year , funds' manager HAVE to purchase FB , all the investment firm whoever has the index Nasdaq-100 will have to replace the infosys (INFO) to FB .
You need to learn when a stock is overbought and oversold. The MAFTrader FMA Data scale would have saved you from making those bad trades. FB will continue to move higher as long as the FMA Data price is at FMA-1% or higher. FB closed above the FMA price which is currently at 27.25. This stock can still move higher. Hold onto those long shares for now.
I'm really nervous right now. I 'm afraid the stock went from $19.8 to the current price too fast, people may take profit and insider may sell to pay tax before year end, may cause the stock to pull back to the low $20. If that is the case I may loose another 70 grand. :( . Pray for me to get out safely.
