OK, you might like this, because I'm sure similar mornings have happened to you, LOL.
I'm checking pre-openings, news, etc. I see CC raised dividend, and is trading much higher pre-open. I say out loud "I should probably take CC out" - "ah well, let's see what happens".
Opens at 27.10, I'm short 3000 shares. Gaps up to .45 so now I'm down $900...I just watch for a minute...BTW, I have 6 fills total. Then CAT opens, which I took out a couple of weeks ago because the price is just too high....but since I "reloaded" my spreadsheet, CAT was still in there. So, now CAT opens at 73.50, and gaps up to 73.85 on a couple of trades. Only 2000 shares on this one, but now down $700 on this sucker.
OK, so I cover 4 stocks with a $400 profit, but I'm focused on CC and CAT. Well, good news is that when CC started to come down, I scaled to cover, actually making $100 (of course, then it went down another 30 cents or so, LOL).
I go ahead and cover CAT at a 13 cent loss, netting about $250 overall...step next door to chat with my traders...and say "you watch CAT drop like a rock now that I covered" - in the 90 seconds to get back to my machine, CAT goes .29 bid offered at .51 (I covered at .63), prints down to .37 and I had already covered.
Anyway, I know we all have mornings like this... and it "coulda been bad, coulda been worse".
Have a good day,
Don
