Everyone please review SEDI filings before getting all excited. This individual has in excess of 2M shares (likely as a result of the Denselight acquisition deal). He has a further 900K options. The man sold 50K shares for proceeds of $16,000. If he was bailing out the numbers would bear that out. 

Sure the market players may try to use this information to their advantage but really, the guy wanted some cash likely for something sweet. He has a very significant incentive to see this thru to a much higher SP
