With the recent implementation of parts of the U.S. Department of Labor’s fiduciary rule, advisors are sharpening their pencils when it comes to performing due diligence on equity and fixed income holdings in their clients’ portfolios. The good news is that advances in financial research and technology have made it much easier to dissect individual funds, or even a combination of funds, in different ways (sector, country, factor, etc.).
These tools help advisors better understand what’s truly driving the results of the funds that they use. Importantly, performance attribution also supports their efforts to ensure that the fees they’re paying for the exposure they desire make sense.

Notes: This is a hypothetical scenario for illustrative purposes only. It does not represent any particular equity investment. “Noise” refers to the fact that through any period, some degree of randomness always affects results versus the broad equity market. The degree of influence varies and can be difficult to statistically distinguish from alpha without extensive data.

Performance attribution, including through a factor lens as illustrated in the chart above, is a standard part of our due diligence when evaluating the roster of subadvisors of our actively managed funds and our internal active teams. While quantitatively oriented due diligence is important, Vanguard strongly believes that qualitative due diligence of firms, people, philosophies, and processes is critical as well.
While many advisors may be content with what they find after conducting a performance appraisal, in some cases they may be surprised to learn that what they’ve been getting from a certain traditional active manager is just a consistent, long-term tilt toward one or more well-known style factors (e.g., credit, term, value, small-cap) when their objective for hiring the active manager may have been solely to generate positive alpha.1,2,3 Low-cost options (implementation tools) to tilt portfolios toward many of these factors have existed for more than 20 years, with style box equity and fixed income index funds representing some of the early options.
Two important questions
Fast-forward to today, when hundreds of options allow advisors to add factor tilts across asset classes if they philosophically believe those tilts can help their clients meet a specific investment objective. As a result, advisors who notice that their traditional active managers have demonstrated persistent and steady factor tilts need to ask two important questions:
- Is this overweight to a certain factor or set of factors something I desire?
- Are the all-in costs for obtaining that exposure suitable, especially if the manager has not delivered positive alpha after adjusting for the factor exposure(s)?
If the answer to the first question is no, then the advisor should consider a more fitting approach or option to achieve the tilt the advisor is looking for. If the answer to the first question is yes, then answering the second question will help make sure that the price the advisor is paying for the types of returns the advisor is receiving makes sense. This is increasingly important now given the growing empirical evidence that, historically, low cost has tended to lead to better long-term performance.4 The trend of cash flows shifting to lower-cost funds was pretty steady over the 15 years ended December 31, 2015, which shows investors are paying attention to costs.
