I'm not really picking o you. What percentage of your net worth are you putting in? How many black swan events have you lived through? Some people never get caught and look like geniouses. Doesn't mean they discovered a secret.
i can understand selling naked options, it's the best trading method there is for well capitalized talented traders. but spreads i don't understand the value of at all your just complicating something that doesn't have to be. spreads are only the last resort of someone who is looking for a step above gambling. it allows them to be in the game and lose money at the slowest rate. if you can trade spreads successfully then you can trade the outright successfully. they would only benefit a money manager who is participating in commissions on a fee basis.
I respect what you have to say but don't understand why you do not like spreads. They are a way to reduce risk, as you know, by capping your loss. I like credit spreads (both puts and calls) on the SPY depending on how the market is doing. I like them just a few days out and aim for a small credit that I can reproduce many times. I have just started credit call spreads recently and am tracking them to evaluate expectancy. What I like about the SPY is that there is expiration several times per week. I realize this is not for everyone.
