To lighten things up on this thread, I have to tell this story of my experience SELLING PREMIUM.
I was a programmer at the time working as a contractor for a small corporation. I was making good money at the time and had started an account at Brown & Company, a well-respected retail firm at the time (1998). I was able to connect to my account and place trades from work which was pretty nifty at the time. However, I wasn't doing that well trying to swing trade by buying options. After doing some reading, I discovered that option SELLERS were more often profitable than the buyers. So one day, I decided to give it a try. I was not aware of margin requirements and I placed a trade one Friday shorting 3 NDX puts. The Nasdaq had been going down all week and I thought it was overdue. Well, I get filled that Friday afternoon as the market was swooning. Monday morning comes around and I get a call from Brown about a margin call. They said I needed ANOTHER $20k into my account to cover the short put positions. I was floored ! However, by the time I had returned the call, my position was up $2000....as the market rallied mightily. The Brown rep told me "nice trade" and then hung up...not too intent on the margin req. I was so full of myself, and the next thing I did was say "I'm never going to close this position, I'm gonna take ALL OF THE PREMIUM". It was 2 weeks till expiration.
The market stayed flat after that one day rally and I got a bit worried. Then that Friday, the one before the expiration, the market started to tank. I kept checking my position and my profits disappeared. I was now at a loss and it was 3 pm that Friday. The final hour was ugly: straight down. Now I was down $3k. Surely, I was going to be closed-out by Brown I thought to myself. I covered my position at 3:55 pm and took the loss.
Monday morning came and the opening print for my puts was 60 !! That would have been the price that Brown would have covered me at. It would have been a loss of nearly $18,000....wiping out my account.
True story. Know when to fold em, know when to hold em.
