Ascent Solar Technologies Inc (ASTI)

There are a number of reasons for insider selling. Best case scenario is they need funding. Worst case scenario they're lining their pockets. Insider selling isn't a problem if they're using the funds for the company. It's a problem if it's used for greed or fear. One can only speculate. I doubt the Germans will tell you/us or give an explanation as to why the sold shares anymore as to the reason they buy shares.
