Potential 2Down 2Up Weekly Reversal For Mmm: Per the Strat, this week I'm watching ticker MMM (3M Co) for a weekly entry trigger at182.85 (last weeks high). If that trigger is met, I'll look for it to reach a magnitude of 187.92 (week before last weeks high). If it can reach magnitude, then it could also continue up to previous highs. Just look out for exhaustion risk to the upside if it continues up after the original 187.92 magnitude.
