Quote from dagnyt:
All he is saying is that a wipeout is possible when you sell naked options. Period.

I don't plan to ever be short even another one-lot.
I am surprised at this kind of thinking coming from a former market-maker. From you I would expect answers like "sometimes", "maybe", and "compared to what?". Naked short premium does not equal bankruptcy, and long premium does not equal profit. Options portfolios cannot be viewed in simple absolutes. When you sell penny vertical credit spreads, you are exchanging one kind of dangerous risk for another. When you sell naked ATM SPX strangles instead of buying stock, you are exchanging one kind of risk for another. When you deposit funds with Maverick's firm in exchange for leverage, you are exchanging one kind of risk for another. Trading is a complex decision making process. When people try to make complex decisions quickly, they tend to rely on simple heuristics. Learn not to rely on heuristics. Specifically, learn not to rely on the very common, very false heuristics reiterated hundreds of times in this very thread:
1. 95% of traders loose
2. 90% of options expire worthless
3. Selling naked premium is too risky
4. Selling naked premium is more risky than selling penny vertical spreads or other "credit spreads"
5. Mathematical probability and expectancy are the same thing
6. Buying or selling an option always has a negative expectancy because of the bid-ask spread
Stop comparing apples to oranges, oranges to snakes, snakes to orangutans. Learn the specific kinds of risks applicable to your specific kind of position, your specific scenario, your specific net worth. For f**cks sake, stop relying on random representativeness selections from the universe of trading mantra. Stop referencing the most available examples of firms or funds that survived or exploded to support your conjecture about the validity of a particular strategy. Its just one curve fit or another, one random uptick or another.
