Zach, you're right volatility is currently through the roof. But I checked out this strategy with the Options Toolbox from CBOE and even with a 20-25% volatility you can get better than 4% per month.

What I am concerned about is the margin requirement. It is very low for a far out of the money naked call, but when it gets in the money, watch out! Example

SPX 1000
Sell 1080 call for 8
margin requirement = (100,000*15%)-8000 + 800 = 7800
Min is 10% for broad index, thus margin is 10,000

Margin requirement is recalc'd every day

SPX 1150
1080 call = 85 (before expiration)
margin requirement = (115,000*15%) + 8500 = 25,750 !!!

We all know we can roll up and out when a short call moves against us, but the margin requirement can get prohibitive.

This makes me feel that I should keep 30% or more or the value of the index laying around in case of a big move upward.

That definitely hurts the % monthly return.
