Quote from yip1997:
20% was a rough estimate. There is a formula for it. It changes with the stock price. margin requirement is not the same as your risk. Don't write naked options if you don't understand the risk.
I forgot to mention that. The margin requirements changes on a daily price as the underlying PPS fluctuates.
Rather than thinking about all this premium you could take in by leverage/selling naked puts, you can very effectively and practically utilize this strategy as you would putting in a limit order to buy a stock at a lower price.
In other words, if you really liked Yahoo and think MSFT is gonna buy it this year, but dont wanna pay current market price. Say you want to pick up 300 shares and have the funds to do so. Than you could sell just 3 put contracts and at least make some money as opposed to just putting in a limit order to buy as the average person does.
But just to simply speculate and think that a stock price will behave in a certain manner while selling a boat load of puts is not the way to go. You might be write once or twice, but it will catch up with you. Remember, you are only as good as your last trade. At one point a while back, I blew out 3 years of gains because I was stubborn and kept increasing my exposure to the S&P 500 by writing more and more puts.
