The thing with the 200 million MC though, is that it's not totally unwarranted at this stage IMO. It has run really hard in a short amount of time as you say, due to nearology and sector sentiment. But look at what NSE have (figures are off the top of my head, so happy to be corrected):

BRU shares worth $53 million
Elixir shares worth approx. 3+ million
Cash approx. 22+ million
Conoco deal worth $109 million

That comes to around $187 million of a 200+ million market cap. I know I'm being simplistic, but there is value there even without the hype. Not sure how high BRU can go, but I still think it's got a bit left in it, which will benefit NSE.
