Lucky: Considering the article was from the days when they were an entirely different entity called Cornell, it is safe to say they didn't get caught.
Heck, that article ShareSleuth's website's owner was fined for insider trading, sued to have the charges thrown out, and then again had them re-issued by the US Securities and Exchange Commission.
So before everyone thinks is such a "must read" article on the evils of insider deals, you might want to consider the source was subsequently, and is currently, charged with insider trading. Allegedly, of course. The article demonstrates what is right, and what is wrong, in the securities world is in the eye of the profiteer.
