Fat tails disrupt all option pricing as risk is undefinable although people try with normal distribution curve.
I doubt that... fat tails will be priced in the moment it gets heavily traded...
Fat tails disrupt all option pricing as risk is undefinable although people try with normal distribution curve.
is if I were a long term investor, my buy and hold SPY returned slightly better than writing calls and slightly worst than put-write ....So why do I care about Sharpe Std Dev... and why go through the troubles of writing calls and puts for a fraction of a percentage in absolute returns if my time horizon is 20+ years?
To enhance returns, specially when it comes to seasonality. The summer is usually slow and sideways, so writing calls (or even puts too) gives you a few extra %. The autumn is usually very bearish so if you are not in cash, writing deeper ITM calls protects you more.
