I don't believe that is an option,at least in any great magnitude that is. The SEC has requirements for reporting 5% and !0% of an individual company's stock. If there was that magnitude going on we'd be seeing the price rise, at least gradually, past these low numbers of the 30's and 40's.
Of course anything is possible but without the proper reporting of such happening i don't believe that is in the cards. JMHO
