Why insider trading matters?

When insiders buy shares on the open market, this can thus be regarded as a strong endorsement by those that know the company the best -- they are literally betting their own money on the company's future. Insider selling, however, is not necessarily meaningful in any way, as there is a range of reasons for insiders to liquidate (some) of the shares they own.

PENN NATIONAL GAMING INC (PENN) - PENN took a deep dive from $36 to $5 due to the crash, anyone who was bold enough to pick up some shares in March or April could have made a 900% profit in 2 months. But bottom fishing is always easier said than done, if one took a safer bet and followed multiple insider buying around $18, a 100% profit is still impressive.
