...and that's just me personally... Everybody is different. If you have a consistent trading approach for earnings versus just getting long or short before the announcement (based on a hunch or TA or tea leaves or whatever), then more power to you.
You could post bids/offers at the lower/upper ranges of the projected earnings move and grind it out through the announcement. You could have a plan going in, but you're still relying too much on hope IMO.
I feel like it's a gamble.
I don't know how one would take a systematic approach towards trading into an earnings announcement. I'm sure the mathematics science PhD might have some valid ideas, but I'm not that guy...
