You are right drkaz, and also today's volume is low. As we can see the trend is not reversing Some people are looking to lock in a quick profit. We will see big moves after the result of EbolaCide and FluCide. FN
The net gain (long-term) for NNVC in value may be significant,.... once that big piece of illiquid infrastructure starts producing a product that can generate revenue. But for the moment - what the market is seeing is the at-hand cash for a company with no existing revenue stream (other than share sales) just went down by a bit more than 10%. This purchase raises the perceived risk (in the short to medium term) that the company will need to do a dilutive share sale sooner than the market might have predicted, and shareprices fell accordingly.
BUT - All of this could change almost instantly once that plant is a net revenue generator to offset that capital input.
"Mr. Market" tends to see only what is immediately estimable and in front of it though,.... When NNVC gets its "breakthough",.... then "Mr. Market" will almost immediately cease to be oblivious.
