I wouldn't speculate the returns of any funds into the future.  I can't magine any basis for such speculation other than you might think that the future will be like the past... and it is sometimes.

I own both funds... I did move my FNARX holding to FSNGX.  I think that natural gas in under-priced vs oil... and oil has gotten awfully pricey.  While energy prices will (and should) remain high, I think that there will be an attempt to roll oil prices back a little.  It is almost a necessity to avoid a world wide economic slowdown.  Natural gas is a fuel that has a lot going for it - namely it is a lot more plentiful in US than oil and it is a clean burning fuel relative to coal and oil.

FICDX has more energy and natural resources than most country funds.  Canada is a country that has a lot going for it... politically stable democracy, more energy and nat resources than its relatively small population needs, proximity to large market for its goods, good current accounts position that strengthens its currency, and good rule of law (though sometimes you wonder about it - the massacre of CanRoys comes to  mind).  The performance of FICDX has been very good over a very long time.
