power11,
I am just guessing here because of the limited basis you gave us for initial look into NWBO but a bio analyst is probably looking at the science and not overly concerned with the financial situation because primary completion of the Phase 3 is expected soon. The 6 months he suggested is probably expected news plus data lock until readout and a 3 to 4 month cushion for any delays due to considerations with regard to multiple regulatory agencies that may be trying to coordinate their efforts or other factors. A six month wait for price moving news would certainly lead to depressed price financing before then as a recent loan received will not get them there. On the other hand this loan of over $2,000,000 is seen by several here as a clue that news is expected much sooner. So take that for what it is worth.
There is definately risk here but I think your friend is looking at the risk/reward ratio and suggesting you consider getting in on that basis alone at a level that takes the risks into very careful consideration and are not just pushed aside for the hope of some enormous reward. Best wishes.
