A Bull Put Spread is an options income strategy where you sell a put at a higher strike and simultaneously buy a put at a lower strike — both with the same expiration date. You collect net premium upfront and profit if the stock stays above your sell strike at expiration.
The single biggest risk reduction comes from stock selection. Only sell puts on companies you would genuinely want to own. This is the core principle of the Wheel strategy.
