5-day chart captures the run up. (Remember this is a dynamic chart so if you read this on Thursday, it doesn't capture that first flat day.)

Look at the volume spikes yesterday and earlier today. Now, volume has dried up. So the question is -- did someone cover a massive short, or go long, or in AlanC's opinion run it up so they could re-short?

We'll know soon.
