Imagination running wild again. It is narrow minded to jump to conclusions without all the facts. My average price is nowhere near $3.50. It is highly unlikely that a poster will place a trade and then immediately post on HC (though 1 or 2 out of 1000s might) to reveal that trade. A sentiment change on HC is not reliable for anything; it would infer something only if a person placed a trade, and logged onto HC, changed their sentiment that instant, and whoever is interested spotted the change at that time. Also a person might plain and simply forget to change their sentiment.
Drawing conclusions based flawed analysis is dangerous. I'm doing pretty well, thanks for asking!
