It wasn't just shorty that ran us back down to .55, it was massive profit-taking. It was a huge run that happened really fast, so profit-taking was to be expected.
Shorty helped it back down but he also covered at .55-.60 like any half-way intelligent trader would do. Over the past 3 days we've seen a very healthy move back up to the .70s range with small pullbacks and consolidation. And some huge block buys from the big boys.
I don't think shorts will be a factor this time in the .70s. We just need volume to push us up into the .80s, which I think is very likely today.
