$heff's $tation of $tocks & $olid DD

[trade2much]

Sheff - your GTXI short of float position agrees with Finviz very closely anyway, but yahoo is widely different. I assume it is due to yahoo using a larger float number than Finviz or your source, since the short shares are the same and reported twice monthly.

I guess then it begs the question of why the float numbers are almost 2x as high on yahoo as on the other sources? See below

Any idea why that rather large discrepancy? TIA for the help
