Fidelity Gas, Medical Mutual Funds Jump

As Fidelity Investments has become the largest U.S. manager of mutual funds and provider of 401(k) accounts, the Boston-based firm has attracted customers with its one-stop financial-services model, counting 24 million individual and institutional clients with $1.4 trillion under management. As its funds go, so does the wealth of many Americans.

TheStreet.com Ratings has been reviewing the best-performing Fidelity stock mutual funds so far this year.

The Fidelity fund with the highest return through Feb. 9 was the Fidelity Select Natural Gas Portfolio(FSNGX Quote), which jumped 13.6%. Of the company holdings focusing on exploration, transmission, distribution and other services related to natural gas, standouts include Tesoro(TSO Quote), with a gain of 40.3%; PetroHawk Energy(HK Quote), with an advance of 38.3%; and Transocean(RIG Quote), with an increase of 28.6%.

The second-best-performing fund was the Fidelity Select Medical Delivery Portfolio(FSHCX Quote), gaining 10.9%. UnitedHealth Group(UNH Quote) and Medco Health Solutions(MHS Quote) dominate the fund, accounting for 17.2% and 11.2% of assets, respectively. Of the noteworthy holdings, Cigna(CI Quote) appreciated 32%, and Aetna(AET Quote) climbed 20%. Medco Health Solutions rose 13.2%, and UnitedHealth Group returned 11%.

While none of those funds contributed to Fidelity's victory in the "Ultra" Fund Family competition, they remain funds to watch for potential upgrades if they are able to sustain their momentum over the next few months.
