Insiders are playing with options!
We can see in "Ink Research" that the officers and directors are frequently exercising options and selling on the Market, dropping the share prices. Then, when the price is low, they proceed with new options granting. They repeat this game from time to time and this explains why this stock is so volatile. Market makers know the game and the profit from the nervousness of shareholders during prediod of low activity like we see this week. If you want to make money in the stock market, you must be on the same side of the steelers...!
