Global Closed-End Funds Get Biggest Upgrades

The largest upgrades to the TheStreet.com closed-end fund universe for the month of May came predominantly from global equity, municipal state and energy/natural resources.

The pick of the list below are represented by the top five funds -- two global equity funds and one municipal fund from BlackRock -- and two municipal funds from Nuveen Investments.

If energy and natural resources is more your sector then there are three to choose from: ING Risk Managed Nat Resources(IRR Quote), Tortoise North American Energy(TYN Quote) and the Tortoise Energy Capital Fund(TYY Quote).

Whether the current run-up in oil prices is a function of easy money combined with actions of hedge funds or the result of supply and demand imbalances or both will be made clearer if the Federal Reserve is forced to raise rates later this year.

If you're of the view that this is a supply and demand issue that won't be corrected in the near term, energy (especially oil) is the place to be. If you think oil prices are a result of lax monetary policy and higher rates will bring commodity prices down, energy may not be for you.

If rates are set to rise, you may also want to stay out of the way of municipals as their prices will fall in sympathy with rate rises.
