FFIV has seen a significant drop of 7.31% in a single day, presenting a potential credit put spread opportunity. However, we should wait for a reversal signal to confirm a potential trend reversal for higher probability of success.

Based on the current stock price of $277.69, here are the suggested strike prices: - Sell Strike: $250 (9.25% drop from the current price) - Buy Strike: $235 (5.5% drop from the Sell Strike, or 14.7% drop from the current stock price)

If a reversal signal is detected soon, we could open a credit put spread with the suggested strikes and an estimated credit of $12.50 per contract.

Please note, this is a strong opportunity with a good risk-reward ratio, but we should always be cautious of a potential dead cat bounce. Therefore, it is crucial to wait for a reversal signal before proceeding. This is a potential long-term bearish play based on FFIV's recent underperformance.
