100 --> 1 is it really "proof"?
while i agree w/ya that NSS does exist & those you call "hedge hogs" can & do decimate shareholder equity via NSS, i can't agree that the scenario in that filing is necessarily "proof" of NSS.
until you can rule out the fact that the company (who has an "E" & isn't timely w/their reporting requirements), has not surreptitiously bloated its share structure to the extent that the sock drawer guy's position is no longer 100% of the total O/S.
example: stock has 100 O/S as of last report.
company increases O/S to 1000, but fails to report it.
sock drawer guy buys 100 shares & puts 'em in the drawer, thinking he owns 100%.
next guy comes along & buys 15 shares & thinks he owns 15% of company's O/S.
another guy buys another 15 shares, also thinking he owns 15% of O/S.
however, when reality sets in & the company reports the tenfold O/S hike, guys 1+2+3 really own a total of 13% of the total O/S, not 130%.
