Vanguard Group named new portfolio managers for three of its mutual funds, including the $5.6 billion Vanguard Strategic Equity Fund (VSEQX).

James Troyer, a principal in Vanguard’s quantitative equity group, replaced Joel Dickson on the Strategic Equity Fund. Dickson has been moved up to direct all of the company’s actively managed quantitative funds.

Donald Kilbride, a vice president of Wellington Management Co., took over the $980 million Vanguard Dividend Growth Fund (VDIGX). He succeeds Wellington vice president Minerva Butler. Wellington, which has managed the fund for Vanguard since December 2002, suggested the change, a Vanguard spokeswoman said.

In addition, two portfolio managers from Chartwell Investment Partners, Mark Cuneen and Edward Antoian, were added to the $620 million Vanguard Mid Cap Growth Fund (VMGRX). They join Evelyn Lapham and John Yoon of Provident Investment Counsel, who have piloted the fund since 1998.

Vanguard also announced that it plans to introduce an actively-managed small-cap stock fund.

The new Strategic Small-Cap Equity Fund would use computer models to invest in stocks in the MSCI Small-Cap 1750 index that Vanguard believes “offer a good balance between reasonable valuations and attractive growth prospects relative to their peers.”

The fund, which Vanguard registered with the SEC on Wednesday, would be exclusively managed by the quantitative equity group, which oversees more than $400 billion in assets in other Vanguard funds and has been solely responsible for running the Strategic Equity Fund since its inception in 1995.

The new fund, which Vanguard expects to debut in the second quarter, will require minimum initial investments of $3,000 for regular and individual retirement accounts. The fund’s expense ratio is expected to be 0.40%, Vanguard noted.

James P. Stetler, a principal and portfolio manager in the quantitative equity group, will manage the new fund. Stetler also manages a portion of Vanguard Morgan Growth Fund/Inv (VMRGX) and Vanguard Equity Income Fund/Investor (VEIPX).
