NEW YORK (TheStreet) -- Fidelity Investments represented 29 spots on TheStreet.com's Top 200 Stock Mutual Funds list in the fourth quarter, winning the 10th consecutive "Ultra" Fund Family title.

Fidelity, which has 820 mutual funds that carry ratings, beat out 411 other fund companies. Fidelity had 28 of its 620 rated mutual funds in the previous Top 200 ranking.

Vanguard retained second place with nine funds on our Top 200 list, which compiles A and A-plus rated mutual funds. Grey House Publishing published the results in TheStreet.com's Winter 2009-2010 Guide to Stock Mutual Funds.

Tied for third place are Alliance Bernstein, a unit of Axa SA ( AXA) and John Hancock, a division of Manulife Financial ( MFC). Transamerica Funds, a subsidiary of Aegon NV ( AEG) slipped to fourth place.

To level the playing field among 33 massive, 35 big, 66 medium and 278 small fund families, we review each of the 412 fund families against peers of similar size.

For a company to be considered an "Ultra" Fund Family, it needs to have the highest percentage of funds ranked in the top 30%. The top 30% represents investment grades of A-plus to B-minus. The middle 40% are fund grades of C-plus, C and C-minus, with D-plus and lower in the bottom 30%.

Van Kampen, a unit of Morgan Stanley ( MS), won the top spot for fund families with 100 or more rated funds for the third consecutive quarter. Van Kampen has 52% of its funds rated "buy."

MFS, a division of Sun Life Financial ( SLF), takes second place with 42% of its funds ranked in the top 30%. Lord Abbett is third with 41%.

Of the 35 big fund families with 40 to 99 rated funds, Royce Funds, a subsidiary of Legg Mason ( LM), was bumped to second place by T. Rowe Price ( TROW). T. Rowe Price had 57% of its funds ranked as "buy," compared with 54% for Royce Funds.

First Eagle Fund retains the "Ultra" fund family crown within the group of 66 medium-sized fund companies with 10 to 39 rated funds by, again, having 12 out of 15 rated funds ranked in the top 30%. Schroder Funds, a unit of Schroders PLC ( SHNWF) took second place with 58% top-ranked funds, while Thornburg Funds rose to third place from fourth, also with 58% "buy"-rated funds. The tie breaker was won by Schroder with a higher percentage of funds in the "hold" range.

The "Ultra" fund family leading this group of 278 fund families with less than 10 rated stock mutual funds is Oak Associates Funds, which kept all six of its funds in the top 30% of our rankings. Harding Loevner Funds and Parnassus, both with five of five funds rated "buy," score 100% top-rated funds and earned honorable mention.
