I'll give you an example of what I'm talking about...Typically the days leading up to one of these announcements will either be in "drift mode" or range mode...Those are opportunities to leg into spreads in options...If done correctly, you will typically get into them for less than what they are trading at (if executed all at once)...With futures trading and the need to have stops in the market, it can sometimes be far too "binary" and the risk of getting the stop hit and then having the market reverse in your favor is always a big possibility.
Of course, there is always a great deal of risk in legging into spreads, but without ticket charges, etc...1-2 lots at a time can be done and it is certainly not as much risk as futures trading (fractional positions, etc).
