The option wheel strategy is a very common simple strategy.
I sell cash secured puts, one week out, at around a 30 delta and collect the premium. If it expires worthless, great. If I get assigned, then I'd like to 'hedge' that position by getting into a high leverage device to balance my positive delta with an 'equal' negative delta. Since my goal is to collect premium, I want to be overall delta zero.
Once 'pegged' at my assignment, I sell week out covered calls against it until it gets called away. Then I go back to the puts.
When I'm pegged, I'm subject to down side risk that I'd like to offset with a hedge. This would reduce my risk when selling the calls. If the market slides while I'm pegged and I sell a covered call below my basis, the difference can really add up fast.
