Loss: reaches its maximum if the stock at expiration is at or above a higher strike. It is equal to the difference between strikes minus initial credit.
Risk: limited.
Reward: limited.
Time decay: if the stock is midway between the strikes, there is no time effect. At a higher strike, profits increase at the fastest rate with time. At lower strike, losses increase at a maximum rate with time.
Research Findings and Trading Tips:
1. The more bearish you are, the lower strikes you should select. It gives you more credit and requires more substantial stock price downward movement to realize the profit potential.
2. This strategy doesn’t require any investment because this is a credit spread. It only reduces the buying power of trader’s margin account.
