R59- DD is fine, but my opinion is,
it doesn't matter. That is, in my experience, no matter how much dd I've done before holding into a report, I'm the worst of it for holding into earnings. I realize you say "most of us" do better than 50/50, but you'd have to prove that to me with at least several hundred reports over a multi year period . My study was approx 1000 quarterly reports from about 125 companies for 8 quarters during a two year bull market rally, and showed an almost exact 50/50 probability of gaining or losing on the session after earnings were announced.
