I agree that a R/S su*ks, but I have the feeling that this will indeed be one of the rare instances of a R/S that could have a positive effect on the share price, similar to one that is applied in order to uplist a company to a higher stock exchange.
The share price has already seen hefty depreciation over the last 2 years or so and thus lots of weak hands have been shaken off. Those who stuck to their investment knew that a R/S was looming over them all along and they also knew that a R/S was the lesser of the evil as compared to a NASDAQ delisting. So yesterday's decision didn't really come as a surprise to anyone even though I had hoped they could drag out the decision to R/S for some more months, maybe even until after the phase 2 data was released. But I suppose the recent NASDAQ hearing panel didn't give them any other choice but to apply a R/S or get delisted.
Now CUR shareholders have finally certainty. What had to be done was done and we can move on while remaining an attractive investment target for funds and other institutional investors.
Remember though that this an investment which likely needs a few more years to really pay off. Nothing for the impatient kind of breed.
EDIT: Also, don't forget lot's of potential investors have CUR on the radar for quite some time now, but certainly wanted to wait for the R/S first before investing. Just look at e.g. the amount of watchers CUR has on StockTwits. Others have sold prior to the R/S and are now waiting to jump back in.
That's why I also think the SP won't see too much further depreciation.
