What is Vanguard’s best thinking regarding portfolio construction?

I am often asked this question by investors trying to make sense of the myriad of choices before them. Who can blame them when they are faced with an ever-growing set of choices? Indeed, many investors whom I speak to want me to cut through the pages of analysis that our team of brilliant CFA® charterholders and Ph.D.s have painstakingly prepared and tell them the bottom line. However, discovering the right answer is not that easy.

Instead of making a suggestion, I often ask, What kind of car do you drive?

After some head scratching and quizzical looks from the audience, I explain that it’s highly likely that the questioner and I drive different cars. This is not because one vehicle make or model is necessarily better than another in any empirical way, but rather, we drive different cars because our needs or specific circumstances dictate different solutions. A mother with five children might require a minivan, whereas a couple of empty nesters might be able to get around in a two-seater convertible.

The same is true for investments. There is no one right answer; it depends on an investor’s particular situation. More specifically, for institutions, the right answer often depends on two key criteria: objective and investment approach.

The chart above lays out the major choices for investors and outlines a framework to help find the solution that is best-suited for them. The objectives of institutional investors are listed by column and the investment approaches to achieve these objectives are listed by row, creating a matrix of potential solutions.

The top left-hand corner is a valuable starting point. Indeed, if I don’t know anything about an investor, I typically suggest a market-capitalization-based balanced portfolio. However, if an investor seeks to add value to his or her portfolio via different investment approaches—or has an objective other than total return—the portfolio will inevitably pivot off of this index-based, market-cap approach.

When focusing on a total-return objective, some investors may choose to maintain a long-term strategic tilt in their portfolios, for either outperformance or risk control purposes. For example, investors frequently implement static tilts when they exhibit a home country bias in their portfolios or elect to favor a certain market segment. Some investors may believe that additional alpha can be added to their portfolios through use of traditional active management. Under the right conditions—talent, cost, and patience—active management can achieve outperformance, which over time should compound into a significant benefit. Alternative investments can also be a useful addition to an institutional portfolio, depending on the investor’s characteristics and the nature of the investment.

Because Vanguard is widely recognized as an indexing expert, the recommendation that active investing can be a good fit for some investors may be surprising. But in reality, my reply to, What is Vanguard’s best thinking regarding portfolio construction? is nearly always, It depends. It depends on an investor’s objective and preferred investment approach. For readers interested in delving deeper into the topic, Vanguard’s white paper A framework for institutional portfolio construction1 does just that.
