Weekly Update for week 15 ended 04/25/2008
Humbling week, down 18.5K (16.2%).
Really frustrating week, capped by a disastrous loss on Friday. Did put a new set of automated strategies to work from Tuesday. It was not a good start, losing 5.8K for the week on automated trades. A flurry of trades that boosted my broker's commission, and left nothing to me. My discretionary outing ended disastrously on Friday with a short on PGNX.
The downfall started on Thursday buying POT at 204 after their wonderful earnings and forecast. Didn't expect the amount of sell-on-the-news that followed, coming down as low at 189, rebounded to 196 where I sold for a loss of 4K. Looked like the whole world was trading the stock. (Of course I could have made some money if I held till today).
Friday was the sad day for me. Shorted 8000 PGNX at 13.30, and went way. The stock skyrocketed to 15.70. My position monitor covered at 14.70 after the 10% loss on account was attained. The silly stock came back down to end the day at 13.40. What should have been a meagre $800 loss became 11.3K loss for me. I feel robbed! Seem someone was after me. No more concentrated position on these tiny caps, and no more stop loss.
Always have to look to the future, in hope of better times. I still believe the automated strategies are the way forward: It's just that at times the losing trades are so conspicuous I could have avoided them with discretionary entries, but have to endure them, having decided to let the program do its work.
I would suggest two things if I may - perhaps consider tighter stops, and definitely continue to utilize stops of some form.
Regarding the second suggestion, it is easy for you to look back on your trade now and see that you would have only lost "x" amount of dollars, but the trade could potentially have continued the opposite direction, losing an even larger amount if not for your stop.
