Sell while you can.....not There are many instances where a share price runs ahead of itself and the right thing to do is to sell while you can at an inflated price.
WPX is not one of these situations for 2 reasons;
1 the share price is still extremely low for a company with a fabulous asset
2 One day, maybe soon or maybe not so soon, WPX will be taken over or a joint venture deal will be signed with a government entity (India or China) or with a large miner who wants to get into potash or to expand its potash business. There will be no gradual build-up. There will be no soft music leading into it. Just... BANG... like a flash of lightening and something like a takeover offer for $2 or some such number a share will happen. The share price will then rise to 10% or 15% higher than the offer as speculators will gamble on a competing bid. If you are not on board before the offer then you miss out.
There is no other asset quite like this anywhere; not this size and not this far advanced in an ideal location.
Doubling down would be a better option than getting out while you can.
