FCU is closer to a buyout/bid and has proven 105mm lbs. Anything under $1.20 is still a bargain and the resource estimate has taken a lot of risk away. NXE has an ambitious winter drill season going, and if successful would move their SP up. NXE is still in a higher risk category as it is mostly all  speculation and exploration until they can prove more about Arrow and surrounding claims. NXE and PTU are still fairly early stage. News from any three of the companies will help eachother but PTU has not had as much success as NXE and doesn't quite have the same management team as NXE. In saying that, any successful holes from PTU or NXE could be a new story. If you are wanting to buy all three, I would start by calculating the risk/return on each.

FCU is a fairly safe bet with a great management team,105mm lbs and the potential of a near term buyout. The deposit is open in all directions and can still be expanded to 120, 150, 175, 200mm lbs. The current SP valuation is still very low in my opinion, and with a shallow 105mm lbs deposit we should see an increase even before bid rumours.

NXE has a huge land portfolio and probably the top management team in the Basin. They have been deemed by many as the next FCU, although they will need extensive drill results still to live up to the hype. Drills are currently turning and they have Garrett Ainsworth (co founder of PLS) leading the exploration team. Smaller market cap than FCU, possibly more chance for greater return, higher risk, early stage exploration, well funded, low cost G&A and exploration.

PTU- Early stage, smaller cap, smaller drill program, Spitfire wasn't quite an Arrow discovery but hosted uranium nonetheless. Potentially deep pockets to expand drilling program with the JV with AREVA and Cameco. PTU could also become a potential buyout target for Fission, NXE, etc etc as it is on stike with PLS and Arrow.

In the end, we should know more in February when the drill results come back from FCU, NXE, and PTU. It will give us a better understanding where these companies are going. FCU is less risky since the proven resource estimate and the SP is undervalued having that tonnage. NXE and PTU are more risky with no resource estimate and are fairly early stage. However, there is always that chance they make a huge discovery and potential for a huge near term gain, as well as a long term buyout. Analysts are still amazed FCU proved 105mm lbs on their first resource estimate, and there is no doubt in my mind that people will be amazed at the price FCU gets bought out at. If NXE keeps proving mineralization and FCU gets taken out by a large sum, it will put huge value on NXE.

If you are buying all three, I would put 60% into FCU, 30% into NXE and 10% in PTU. Something like that. As always, do your own DD and also note I do not own any PTU currently but would like to after we see the next drill results. Hope this helps somewhat.
