My guess is that John Fife is taking advantage of the last few day's increased volumes to unload as many of his registered and unregistered shares as possible. So we'll probably see an increase in "short" sales since unregistered shares are listed as such when they are included in the trading figures. So a word to the wise, keep that in mind when opining about any heavy volume of "short" sales going forward.
That being said, I'm sure most of us aren't thrilled by the dip below a quarter, unless one is looking to increase share totals below these prices...
