I am by all mean not to defend Insider Sales but sometimes their action is justified especially on Exercised Options. A lot of other companies' officers do so more than often. One thing to remember; they did also buy out of their pockets when the stock is beaten down. Just like any investor/trader, you need to sell to preserve capital and lock in profit. When a company stock goes up considerably from the 52 week low, I said they deserve to book profit like anybody else. Hope I clarify your question.
