Mutual fund company Vanguard Group raised minimum investments for its Windsor II and Wellington funds and closed a third to slow a flood of money and protect returns.

The minimum initial investment in the $44-billion Windsor II, Vanguard’s largest actively managed stock fund, and the $41-billion Wellington was increased to $10,000 from $3,000. Strategic Equity, a $7-billion quantitative fund, was closed to new investors, the Valley Forge, Pa.-based company said.
