"I am not rich by any means but when I invest in a stock (particularly when it's a dollar per share), I don't purchase 87 shares, 100 shares etc; it is a MINIMUM of 5000 at a time. I think this holds true for most people who are invested in RVX or why bother."

Those are likely HFT computer trades rather than individual buyers. IMO the HFT trades often buy small quantities at the ask or sell small quantities at the bid in an effort to coax individuals to follow them.
