Eddie, The link which you posted to Chuz contains several errors. The first is the author's claim that 70-75% of options expire worthless. The correct figure is considerably below that. Herm seems to be confusing the percent of options that expire worthless with the percent of investors who lose money. These two are not the same. The percentage of investors who lose money on options is ~85-90% according to Barron's. The fact that the percentage is this high isn't surprising when you consider the zero-sum nature of options. Stock options are side bets on the magnitude and direction of movement in the price of the underlying stock. For everyone who profits, someone else must lose. Because transactions costs must be subtracted from both sides of the bet, aggregate losses exceed aggregate gains. Transactions costs can be substantial, involving not only brokerage fees but also "the spread." Now, the percent of options that expire worthless depends on how option contracts are written. Suppose all buyers and sellers had a preference for out of the money options. That's the way all options contracts would be written, and consequently 75% or more could easily expire worthless. Alternatively, suppose everyone - buyers and writers alike, preferred in the money options. In that case all options would be so configured when initially traded, and a smaller percent would expire worthless. The percent of options that expire worthless doesn't tell you much. It says more about players' preferences for in-the-money v. out of the-money-options than it does anything else. As an indicator of expected return on investment it's worthless. Herm also errs by asserting that a writer who buys a put and a call on the same position is "balancing out his position." This is nonsense. The combination of a put and a call on the same stock written at the same strike price is called a "straddle." If you buy a straddle you are hoping the stock will either soar or crash, you don't care which. Writing straddles on volatile stocks is risky business. Geoff
