do me a favor and check how many shares he owns please. Now why are you concerned about 17k shares? If he knew something he would be selling a lot more than 17000 shares. He prob just wanted extra money for a vacation or somehting. People sell for millions of reasons. People only buy for one reason, and look how many shares insiders have bought and/or own.
Per the filings the CFO now owns no stock in the company. The 17k shares he sold was all the stock he owned, and he sold it yesterday and a day before. Now THAT is what you call great timing.
Boy was he he lucky....LOL!
