A subscriber recently asked the question, “If the market is breaking down and options are expensive, would a call credit spread be the best low risk spreading strategy to use?” It’s a good question, and the answer gets into a dichotomy of sorts – in that a credit spread might not be the best strategy even when options are expensive.
It is sort of a “knee-jerk” assumption that a credit spread will do better than a debit spread if volatility collapses. In reality, that’s not true. If they both employ the same strikes, they will perform the same (otherwise, risk-free arbitrage would be available).
