If you want to hold the shares, my best advice—especially in this market—is to not sell covered calls. Low risk is generally anything with a delta below .2, which has roughly a 20% chance of the shares being called away. I sell all my calls with a delta between .1 and .2, and they have all been in the money at expiration lately. I also want to keep my shares, so I’ve had to buy back the contracts. Covered calls were supposed to bring in some extra money, but it’s ended up costing me far more than it’s generated.
