Thanks for your advice. The only thing worry is big buy-out and PPS could go up 2-5X. As far as making profit in MNKD is buy low and sell high. There is no pressure or rush to buy in now because it take time for the PPS to go up significantly. IMO, you buy low and sell as high as you can. You can make profit right away instead of bag holder for couple years and wait for the high gain in return. Technically, everyone investment to make money and why not make money now instead of waiting for the future. You can always buy back in.
