As the price of petroleum and the stock market collapsed in October, it would seem almost beyond belief that the only closed-end equity funds to gain were energy plays.

Intelligent investment strategies involving energy infrastructure, production and delivery, with a heavy focus on natural gas, helped propel each of the quartet of funds in the accompanying table to positive returns last month. They were the only closed-end equity vehicles with performance numbers prepended by plus signs.

Like virtually all "long-side" stock funds, each of the four is lower for the year to date, albeit by distinctly lesser magnitudes than the

The stated objective of the

Evergreen Global Dividend Opportunity Fund

(EOD) - Get Report

is to "normally invest 65% of its total assets in securities of issuers in the utilities, energy and telecommunications fields." As befits the "Global" in its name, EOD's largest investments are in France's Suez, which is primarily involved in electricity and natural gas, and United Utilities PLC of the U.K., which supplies water -- now commonly referred to as "the new oil" -- and natural gas. Its largest U.S. stocks include

Exelon Corp.

(EXC) - Get Report

, an electric utilities company, and

Questar Corp.

(STR)

, which is in natural gas production and delivery.

The

John Hancock Tax Advantage Dividend Income Fund

(HTD) - Get Report

, because of a creative dividend strategy, is technically classified as an equity income fund.

"Under normal conditions," states HTD, "the fund will invest at least 80% of its assets in dividend-paying common and preferred securities that the adviser believes at the time of acquisition are eligible to pay dividends which, for individual shareholders, qualify for U.S. federal income taxation at rates applicable to long-term capital gains, which currently are taxed at a maximum rate of 15%."

The securities HTD currently holds for its tax-advantaged process are largely involved in the energy industry, with a concentration in natural gas. They include

ONEOK

(OKE) - Get Report

, which purchases, transports, stores and distributes natural gas; energy delivery firm

NSTAR

( NST);

Integrys Energy Group

(TEG)

, a gas and electric utility firm; and

Spectra Energy

(SE) - Get Report

, which holds natural gas assets.

The

ING Risk Managed Natural Resources Fund

(IRR) - Get Report

(MTP) - Get Report

"is to provide a high level of after-tax total return by investing all its assets in a portfolio of publicly traded master limited partnerships operating in the energy infrastructure sector of the market."
