NEW YORK (TheStreet) -- Energy stocks have been rallying lately on rising oil prices.
So far his year, energy mutual funds have returned 3.9%, while the S&P 500 has lost 1.2%, according to Morningstar. A barrel of West Texas Intermediate crude sells for $103, up from $88 a year ago.
Can the energy stocks stay afloat? Some fund managers think so.
"Oil prices will stay high because there is resurgence in demand from Europe and other areas," says Brian Hicks, portfolio manager of U.S. Global Investors Global Resources Fund(PSPFX).
Despite their recent upturn, energy stocks remain cheap, portfolio managers say. While the price-earnings ratio of the S&P 500 climbed in recent years, energy multiples trailed. During the three years ended in 2013, energy funds returned 5.7% annually, compared with 16.2% for the S&P 500. Leading blue chips, such as Chevron(CVX) and Exxon Mobil(XOM) command price-to-earnings ratios of 13 or less, compared with 18 for the S&P 500.
Fund portfolio managers say that the energy stocks lagged in recent years because investors worried about softening oil prices. According to energy bears, markets seemed poised to face oversupplies as U.S. shale production rose.
At the same time, demand was likely to remain stagnant as global economies struggled. But the excess supplies never materialized because of production slowdowns in foreign fields, including the North Sea and Iran. As a result, oil prices stayed firm.
For a broader portfolio, consider U.S. Global Investors Global Resources, a natural-resources fund that holds mining and precious metals along with energy.
Fidelity portfolio manager John Dowd holds a mix that includes fast-growing smaller companies as well as some lumbering giants that may be undervalued. During the past five years, the fund returned 16% annually, outperforming 87% of its peers.
Dowd holds some companies that are growing rapidly by exploiting shale fields. He is particularly keen on developers that have reduced costs through trial and error.
"The companies that have figured out how to improve productivity are reporting better earnings growth than the industry overall," he says.
