Quote from HFStartup:
Yeah, right. I keep hearing that. Usually from traders who don't set aside the capital to buy the underlying if assigned. They strictly trade the options and have no interest in the underlying. Limiting leverage or not using it at all improves the option selling strategies significantly.
Threads like this always seem to get away from the fact that a successful trading strategy is comprised of many parts. If someone sells options, then the risk management, position sizing, amount of capital required to achieve enough diversification, etc. also has to be developed to work hand in hand together. So yes, JUST selling options can be risky, can make you lose all your money, etc. But with a complete system, it can produce consistent earnings in any market.
