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.
