Baird Aggregate Bond Provides Reliable Results Over Time
Little changes add up with this fund.

Baird Aggregate Bond’s BAGIX penchant for incremental progress rather than dramatic leaps has been key to its success within the intermediate core bond Morningstar Category.
The strategy’s preference for small changes over big ones includes transitions within its 10-person management team, such as a recent shift in titles. In early 2025, longtime research director Jay Schwister succeeded Mary Ellen Stanek as co-CIO alongside Warren Pierson. Stanek, who won Morningstar’s 2022 Outstanding Portfolio Manager award, became emeritus CIO. Schwister has retained his research director duties, while Stanek remains a named manager here.
It would not be surprising if Stanek and fellow Baird founder Charles Groeschell retired within the next three to five years, though they have made no announcement to that effect. If so, however, the team would be well prepared to carry on the Baird legacy thanks to its methodical approach to preparing team members for new roles. Pierson, for example, spent more than three years as deputy CIO before becoming co-CIO alongside Stanek in October 2021.
The Baird legacy also includes a straightforward but effective investment approach. Sticking to US-dollar-denominated bonds without the potential complications of derivatives or leverage, it begins with matching the Bloomberg US Aggregate Bond Index’s overall interest-rate sensitivity, or duration, and then allocating to the bond sectors with the most attractive combination of underlying fundamentals, valuations, and liquidity.
Although credit risk is muted compared with more aggressive category rivals, Baird Aggregate Bond tends to favor BBB credits. Since mid-2022, the portfolio’s 21% to 24% allocation to BBB rated bonds has consistently ranked in the peer group’s top quintile.
The fund has a strong long-term record. Since its late-2000 inception, its institutional shares’ 4.25% annualized gain through January 2025 beat the Bloomberg US Aggregate Bond Index by 48 basis points while placing near the top decile out of roughly 65 distinct intermediate core bond category peers. Adjusted for volatility, Baird Aggregate Bond’s results looked even better: The institutional shares’ information ratio (a measure excess return over excess standard deviation versus the benchmark) ranked fourth overall in the entire peer group.
Consistent outperformance has been a hallmark, too. Over the past decade through 2024, Baird Aggregate Bond has beaten its index and distinct peer median in eight out of 10 calendar years. Versus the benchmark, the fund’s best showing was in 2020 when its 8.63% return outpaced the index by 112 basis points. The fund didn’t start that year well, though. Its typical Treasury underweight was a headwind in 2020’s first-quarter, coronavirus-driven credit selloff. Increasing exposure to investment-grade credit after spreads widened helped for the year as a whole, though, as did individual bond picks.
This strategy is a very reliable option.
