Sold MasterCard

I sold MasterCard International (Ticker: MA) today @ $55.38 generating a net return of 19.96% after commissions. The holding period for this position was a little over 2.5 months (purchased on 6/15/06 and sold on 8/29/06). My goal in any position is to generate a short term profit of at least 20% and if I’m wrong, I would try to cut my losses quickly and move on. Now that's the difficult part.
