Selling at delta 0.20 gives your stock plenty of room to run while collecting a smaller but meaningful premium. Best in mildly bullish, low-to-moderate IV environments. At elevated IV (above 70th percentile), delta 20 strikes can yield 15–25% annualized without risking significant upside cap.
Recommended DTE: 21–45 days. Theta decay accelerates meaningfully in this window even at low delta strikes.
