And that's the key Gary, " as long as you are correct in the long term". Critical to remain objective and be willing to sell and move on if the original investment basis no longer exists. Years ago, about the same time I began following NWBO, I also was interested in TXMD, another little biotech. Took a position and followed it as they had an existing line of prenatal vitamins, received FDA approval for 2 women's reproductive system drugs and licensed a third. So looked good, but over the next few years it became evident management was incapable of executing a plan and selling the products. Sold, as I had no faith in management, took a small loss, share price was about $6 when I exited. That was several years ago. Since then, the company has done a 1 for 50 reverse split, sold the right to the products to another company and is slowing dying on the royalty fees from those companies.
It's not easy being a long-term investor in a company like NWBO, has required a lot of patience, especially when your investment has been dead money for several years. Regardless, in this case there is enough potential and promise to keep us hanging on.
