I agree with CS. If you want to be successful in this sector,
(And CS and I have been), you can hardly go wrong following a simple rule:
when it DOUBLES, SELL HALF. This way, you get your capital out, and can use it
in another small cap stock.
I have already sold about 40% of my position in NML (over the past several months), and my "cost" is now under 2P, if I apply my profit to the remaining shares that I hold.
Do I like the stock? Yes. I bought some during the summer dip, with profits from earlier in the year.
