Suresh bought 75k units not 50k. Again though why would these insiders even put up their own money when they have options? Are they not invested enough in the company? 

I am sorry you think I am just cherry picking but your argument does not make sense to me. Why draw a connection between options and insider buying. They have lots of options so why risk their own money? Actually that is one thing that I did agree with the Chris Chiu on when he said it makes no sense for insiders to buy shares in the same company they work for when they have options. He always claimed that it was important for insiders to diversify away from the company rather than being so overweight especially in a start-up.
