Well the actual numbers are: % Held By Institutions = 58; % Held By Insiders = 27; % Short = 41; i.e., retail holders only hold 15% and that more than 60% of the institutional holding is shorted if one-third of the retail holding is assumed to be shorted!!
Thus, the culprit is the institutional holders, meaning a lot of EXEL shares are controlled by institutional hedgers OR, in plain English, these shares are a tool of institutional gambling!! "Nomad effect," while plausible, is just insignificant!!
both NASDAQ and Google list EXEL institutional ownership at 90%. How is it that you have the "actual" numbers at 58%? Institutions routinely "lend" their shares for money to people who short the stock. It's a great way to make money while maintaining their long position. pretty basic stuff.
Correction in the above post: I do not mean what Nomad is saying is wrong; in fact he is very much on the credibility side or being real. What I mean is that his posts on this board have only minor effect, if any, because institutional hedgies do not read these posts. And, the institutional hedgers are the ones driving the share price like a yo-yo. Can any retail holder fight these behemoths? Certainly not. Then, judge for yourself how you want to treat these shares for your investment or even trading.
