Just sharing my observation about its historical behavior for the last two years. Doesn't mean it will do that tomorrow. I'm just looking at the "pop" days. Going back two years on a daily I see seven very large pops. Today's is by far the largest. Just look at the next day after each pop. Mind you - I won't short this. Way too risky for me. But the history shows a significant pullback the day after a huge pop.
