So... let's see what happens. In my experience, if a stock breaches the lower after an report, it's no longer a valid long call trade. In the past, I have made the mistake in thinking with 2 standard deviations... I have a 95% chance that price will fall back within the BollingerBands within the lifespan of the trade. But often what ends up happening is the stock price moves in a "L shaped" pattern where the vertical end of the "L" is the drop after the major news event and the horizontal side of the "L" is the sideways price action the stock experiences for days ( sometimes weeks ) following the news event.
In this situation, the stock usually comes back within the 2 standard deviation range... but not until Theta decay has eaten up your call option's premium. So even if you eventually get the direction right, time will not be kind to your long call position. This is where applying the Put Credit Spread strategy comes in handy. With Put Credit Spreads, you are an option seller, rather than an option buyer. Time will erode the premiums of the spread making it cheaper to buy back later. What's even better, is if the stock moves up... then the Delta will negatively affect the puts making them cheaper to buy back.
Anyways, let's follow Biogen tomorrow and see if they beat or miss and how the stock price reacts to the news. If it heads lower, we'll follow up in next weeks idea regarding the put credit spread setup.
