Ann: FYI Signs MOU With Alcoa to Advance HPA Development, page-38

I agree to a certain extent but:

1. With every new milestone hit the risk recedes as the company has a stronger position
2. Takeover speculation can encourage further price growth as there's plenty of people out there who will see it as a positive to buy in and get a takeover offer for a quick 50% profit, the higher price paradoxically lessens the chance of a cheap takeover bid getting accepted
3. From everything I've read/heard, I trust Roly's financial's acumen and judgement not to sell himself and us short

All in all it's not a bad problem to have!
