I think we have good odds here. Risking a drop to 34.57 is conservative, you could also wager on price not going under 39.50 but I'd rather have more margin of error initially. I'm long from higher and doubled my position here since I think it's a low risk spot for the post earnings momentum to end.
Within the next 3-5 days we should see price move higher. The estimated earnings level lies at 46.61, it's not yet confirmed but it should be close to where the last earnings release key level will be. A 2.8% to 5.6% position is fine for the first entry, to then add as you can reduce the stop loss distance with more confirmation of upside.
Good luck,
Ivan Labrie.
