As more target-date series tweak their approaches in reaction to market events, Vanguard Target Retirement stands out for its steadfast dedication to a straightforward, broadly diversified, and low-cost retirement solution, one that is a direct reflection of Vanguard's deep-rooted investment philosophy.
The series invests primarily in four low-cost, broadly diversified index funds that provide efficient exposure to global stocks and bonds. Adjustments to the asset allocation glide path undergo rigorous evaluation by a committee of senior Vanguard investors with a long-term perspective. That high bar for change is precisely what makes this approach distinctive: Strategic allocation shifts are infrequent by design, not by accident.
For instance, the last significant adjustment came in 2015, when Vanguard increased the funds’ allocation to international stocks and bonds by 10 percentage points. The equity portion shifted to a 60% US and 40% international split, while bonds moved to a 70%/30% split. At the time, this equity allocation maintained a home bias of about 7 percentage points relative to the MSCI All Country World Index, a global stock benchmark. However, as US stocks significantly outperformed international markets from 2015 through 2024, the series’ strategic target to non-US stocks grew to about 5 percentage points higher than the global weighting as of early 2025. International stocks outperformed domestic ones since the beginning of 2025, boosting short-term results for this series. It’s now only about 2 percentage points underweight in US stocks as of February 2026.
Although changes to the portfolios are rare, the team has made updates to its rebalancing policy to help reduce transaction costs. In January 2025, Vanguard reduced the size of a rebalancing trade to 25 basis points from 100 basis points and allowed the portfolio management team to limit unnecessary rebalances in favor of letting markets correct on their own. This built on a similar refinement made in January 2021, when it expanded the rebalancing threshold to 200 basis points from 100 to reduce trading frequency.
Investors furthest from retirement start with a 90% stock and 10% bond allocation. This remains unchanged until 25 years before retirement, at which point stock exposure begins to decline, reaching 30% seven years after age 65. Five years before retirement, investors still hold 59% in stocks—5 percentage points above the norm—and at retirement, the stock allocation is 50%, 6 percentage points higher than the average peer. This relatively higher stock exposure near retirement makes the portfolio more susceptible to market downturns, which could be challenging for conservative investors. However, for most investors, this remains a compelling option for retirement savings.
