Interesting that you brought this up. NWBO slipped to the Pink Sheets for a few days awhile back. Everyone here was saying Les G. did not get the paper work done in time and NWBO, slipped for a few days. This could have been a possible reason NWBO slipped to the Pinks for a few days, so LP could sell some shares. However sells for the most part are not the tell, because everyone needs money. The insider buys are the tell, because the only reason to buy a stock, is because you believe it is going up. At least most of the time insiders believe that. IMO
