Episode 61: The allure of index funds, such as broad diversification, low costs, and market-matching returns, may seem undeniable. But recent "reconstitution" in the indexes tracked by such funds tells a different story—one every investor should understand.

Most indexes undergo periodic rebalancing. As companies grow, shrink, or change their ranking within industries, indexes re-evaluate their securities lineups and make changes once, twice, or possibly four to fix times a year.

That may sound prudent, but the impact on investors can be painful.

Instead of rebalancing regularly as stock prices change, for instance, indexes stick to rigid rebalancing schedules. If you own a small cap index fund, this rigidity can lead to style drift: Over time your holdings may veer from your goal. Additionally, indexes tracking particular market segments may not hold the same stocks, leading to significant performance differences.

Many recent index changes occurred at the end of June. (See "Stock Indexes Are Changing. Is Your Portfolio Ready?" https://youtu.be/8WwLg0C2uP4?si=ecM62TcJm41WKkEi)

Checking on those changes today unearths some surprises. Take SpaceX. The company's massive initial public offering in June led some index providers to change their rules to allow SpaceX into their indexes. Yet several months later SpaceX's performance leaves plenty to be desired.

Numerous other landmines are associated with index reconstitutions. Since the changes are usually announced in advance, institutional investors often buy and sell those holdings before index funds, which can hurt fund returns. Also, investors targeting value or growth may be surprised to learn some value indexes contain growth stocks and vice versa; bothersome overlap is real.

What's the alternative? In Episode 61 of The Informed Investor podcast, Dimensional Head of Global Client Services Mark Gochnour, Co-Head of Product Specialists Rob Harvey, and Head of Client Communications Jake DeKinder take a second look at this year's changes to market indexes and explore how investors can surmount the substantial costs.

Episode 60: Every two years, millions of investors probably ask themselves (and their advisors) whether looming elections demand changes to their investment portfolios. It's an understandable sentiment—and one that demands discussion. But the most important conclusion from these conversations should never change: Since the data doesn't show any strong connection between election results and stock market performance, it's best to vote with your ballot, not your portfolio. No matter how you slice, dice, or take a hatchet to the data, factor in your own political proclivities, or scream about what you think is totally wrong or right about the candidates, market prices have already incorporated all that information (and thousands of other developments, including numerous economic indicators) as investors consider what to do next. This is a well-researched theory of how capital markets work. The implication is that the stock market doesn't really care what you think about this year's midterm elections or the next presidential horse race. Need supporting evidence? Fourteen of 17 presidential terms since 1929, across administrations with both Democratic and Republican chief executives, ended with positive returns for the S&P 500 Index. (S&P data © 2026 S&P Dow Jones Indices LLC, a division of S&P Global.) Investors shouldn't ignore elections, of course. But their portfolios may benefit from standing pat as politics rile and emotions rock and roll. In Episode 60 of The Informed Investor podcast, Dimensional's Mark Gochnour, Head of Global Client Services, Wes Crill, Senior Client Solutions Director, and Jake DeKinder, Head of Client Communications, interrogate common myths about the impact of elections on markets and offer sensible answers as investors head to the polls.

Episode 57: How much of your portfolio should really be invested in alternatives? For ultra-high-net-worth investors and families, alternative investments have long been viewed as a path to diversification, exclusive access, and potentially higher returns. But are they always worth the complexity, illiquidity, fees, and taxes that come with them? We take a critical look at the world of alternatives—from hedge funds, private equity, and venture capital to private real estate and other non-public investments. We explore where returns actually come from, looking at the impact of enterprise risk, financial engineering, and manager skill, and examine whether those sources of return truly justify the additional costs and complexity. We also discuss the role of liquidity, diversification, taxation, manager selection, and investment purpose when evaluating alternatives. Are private investments genuinely less volatile, or do appraisal-based valuations simply make them look that way? And as access expands beyond institutions and ultra-wealthy families into vehicles such as 401(k) plans, are investors really gaining access to the same opportunities? Finally, we look at one of the original homes of alternative investing: endowments. If institutions with long time horizons, sophisticated investment teams, and access to top-tier managers have not consistently outperformed comparable public-market portfolios, what should individual investors conclude? In Episode 57 of The Informed Investor, Dimensional's Mark Gochnour, Head of Global Client Services, sits down with Jeff Coyle, founder and CEO of Libretto. The takeaway: Alternatives aren't inherently good or bad—they need to be deconstructed, evaluated, and compared against the public markets with a clear understanding of where the return comes from and what you're paying to get it.
