Only the company can acquire a list of investors, and then they must be able to spend time watching each and every trade (not generally the best allocation of resources).  This process will give the company an idea of who might be Daisy Chain trading, but for small investors who use discount brokerage houses, the list only indicates that trades were made by the brokerage, and not who the individual was who traded.  So, unless the person Daisy Chain trading is a broker, they are not likely to be found.

What I can tell you is that when good news does come out, the market will overwhelm such trading.
