You make a valid point that he's not about to advise any of the investor's to "sell. " It just won't happen. Ever.
However, I think his conduct speaks volumes. In the monkey see, monkey do world, he bought a shwack of shares in his own company, and he's sitting on them. He may not be buying more at this stage, but he's not selling either.
I honestly think, and I've said this before, that by the sheer number of shares he owns, he has no hope of ever unloading those unless it is to a major. He is betting the highest stakes there are on the belief that his company and the discovery are history-makers.
Someone over at FWR sold 100K shares and the squawking from the peanut gallery was deafening. How much worse would it be perceived if Nemis were to sell shares NOW???
I don't think we'll be seeing him selling any shares, but that's JMHO.
