Jim Lowell is known for his expertise in assessing mutual funds; in particular, he is the newsletter advisory world's leading authority on Fidelity funds.

In his Fidelity Investor, he recently conducted his mid-year ranking of Fidelity managers, and based on these results, offers four favorite funds offering global diversifcation.

"Stephen DuFour, manager of Fidelity Focused Stock (FTQGX), is no stranger to our ranking top notches. He took over this fund in March last year, and turned its performance up a notch (finishing the year up 17% vs. .5.5% for his S&P 500 benchmark): Bam!

"With 52 holdings, this fund is focused. His top 10 basically says it all – a diversified play on global growth in a stock picker's portfolio: Southwestern Energy, Norfolk Southern, Range Resources, T. Rowe Price, NRG Energy, Unilever, Eaton, Cisco, Cabot Oil & Gas, and Apple.

"Tom Soviero, manager at Fidelity Leveraged Company Stock (FLVCX), has jumped from the third spot in the December rankings to the top spot this time around.

"His top-ranked status reflects his stock picking expertise. The portfolio continues to become even more concentrated in his top 10 picks (29.4% of the fund's assets now vs. 27% six months ago).

"For investors who seek superior relative performance but are unwilling to sacrifice dependability, the we offer four funds that consistently outperform their peers," says Richard Moroney.

In the mid-year forecast for his Dow Theory Forecasts, he explains, "All of these funds have outpaced category averages in each of last five years, and sometimes much longer." Here, he looks at those funds that he considers "perennial winners."

"To be sure, past returns do not guarantee future success. But, while the evidence is not conclusive, academic studies generally indicate performance tends to persist, particularly at the extremes. That is, the best funds continue to outperform their peers, while the worst funds keep lagging.

"Fidelity Export & Multinational (FEXPX), our favorite pick among large-company growth funds, is riding an impressive nine-year winning streak - the longest in its category. Among the more than 1,800 large-cap growth funds, less than 80, or roughly 4%, have outperformed the peer-group average for five straight years.
