Growthworks exercised optionsInsider trading reports show two Growthworks Funds exercised stock options on Sept 8th, paying 22 cents for a total of 150,000 shares. They also let some of their 22 cents options expire. I assume this transaction was because the options were reaching expiry date and not because Growthworks had some cash inflow from subscribers to invest.
It is possible that Growthworks is now trying to sell the shares at around 39 cents to show a profit of $25,000 to include in their Sept quarter results. However, they don't want to drop the price much because it would cause a mark-to-market loss on their existing investment.
If there were lots of buying interest in SDI, this wouldn't matter. However, so far, the NY pitch has not created any huge buying interest. So any selling pressure is unhelpful.
