You and other's are probably correct there. I've never seen this tyoe of action before and it seems others were fearful of the possibility of huge dilution. There wasn't fear from those who said the AS was 3 billion but those who thought it was 10 billion had some fear. Not to mention the "gagging" of the TA as futher "evidence."
But, yes, it appears that many were simply greatful to sell some or all there shares aftee that PR laat week and maybe after holding so long, and thinking this was dead.
