A change inside existing funds
Vanguard announced on June 29, 2026 that T. Rowe Price would become an adviser to Explorer Fund, the Variable Insurance Fund Small Company Growth Portfolio, and Growth and Income Fund. ArrowMark would leave the first two mandates, while Los Angeles Capital would leave Growth and Income.
Vanguard said the funds’ objectives and principal strategies would remain unchanged. It expected expense ratios to rise for Growth and Income and the insurance portfolio, with no expense ratio change expected for Explorer.

A new adviser can change the portfolio’s character
FOLITIC analysis: An unchanged objective does not mean identical stock selection. Different teams can reach different conclusions about valuation, quality and earnings durability within the same mandate. The resulting purchases and sales may alter sector exposure or overlap with other funds in an investor’s account.
For a fund using several advisers, the allocation of assets among those advisers also matters. Adding an experienced team is not itself evidence of better future performance. Investors need to see how the combined portfolio behaves and whether its risks remain consistent with the role it was chosen to play.
The review should focus on implementation
The next holdings report can reveal changes in concentration and style, although it will not provide a complete live trading record. Turnover, realized distributions and expenses should be reviewed alongside returns. The announcement is a reason to revisit the investment thesis for the affected funds, rather than an automatic instruction to buy or sell them.
