Yes, I know it was complete dumb luck. A gamble. Speculation. Call it what you will, but I'm writing it down to see if it's possible to replicate the performance. To find another like it. And I'm trading in my tax-advantaged account.
Stock A - DF.
Bought $3000 worth May 9, 2012, after an earnings surprise, after a spike of about 30%. It went down and back up a bit. Sold it two days later, lost just the transaction costs (-20).
Stock B - ARNA
Bought $3800 worth May 9, 2012, after spike of about 25% - once again trying to ride the momentum. After I bought, they suspend the stock from trading for one day while they have a FDA ruling panel to approve their diet pill. By all accounts, it looks like it will get approved.
May 11, FDA approves it. Stock opens and jumps 55%, and I close out my position, pocket $2000.
* I was lucky to get in ahead of the news that I didn't even know about. But I did stumble upon it by price and volume action.
** DF - i think i will stick with under $10 stocks for now.
