A $60 credit means nothing until you know what it cost to hold. The same credit against $190 of buying-power-reduction is a 32% return on capital; against a $4,750 cash-secured-put requirement it is 1.3%. Annualising both makes the comparison sharper still.
The number is easy to game, which is the warning attached to it. Return on capital rises automatically as risk rises, so a screen sorted by it will surface exactly the trades with the worst tails. It belongs next to max-loss and probability-of-profit, never alone.
Example: XYZ at $50. The 45-day $47.50 cash-secured put pays $1.10 on $4,750 — 2.3%, or about 19% annualised. The $47.50/$45 bull-put-spread pays $0.60 on $190 — 32%, or 256% annualised, with a loss that can be three times the credit.
