considering it's massive post-report move in the last 9 EAs, would you do a front month ATM straddle (EA on Wed)?
I haven't traded WFMI, but looking at the multi-year chart, it looks like it always makes a reversal shortly after the earnings reaction, and retraces quite a lot. So it might be worth waiting a day or two after earnings for the IV to die down and then go long for a directional trade.
