Why You Need Active Management: Every Bear Market Is DifferentAdvisor Perspectives
Years ago, after learning in school that no two fingerprints are alike, my kids spent weeks trying to match their fingerprints to other people to disprove their teacher. Besides the practical aspects of having a limited number of test subjects, they never came close to proving the teacher wrong (although they kept thinking they were right). While fingerprints do have similarities, trying to find two identical ones is near impossible.1
Much like the uniqueness of fingerprints, finding two bear markets that are identical is almost impossible. All bear markets involve market stress, but no two are alike. A variety of factors can cause them, including unexpected changes in monetary policy, political events, overvaluations, bank failures, natural disasters, wars, and deleveraging in various forms and combinations.
Trying to anticipate whether any of these possible catalysts will manifest and how they might affect equity markets has proved to be quite difficult. And it’s no different with professional asset managers, whose performances are also almost impossible to predict, as we’ll see below. However, we believe certain factors can improve the probability of success using active management.
Two bear markets, different fingerprints
To see how difficult it is to predict investment performance, we looked at the differences in returns of various market sectors and segments during the last two bear markets.
When the tech bubble burst in the early 2000s, IT, telecom, and utilities were the worst-performing sectors. During the global financial crisis, REITs, financials, and industrials were the ones to avoid. In fact, REITs was the best-performing sector in the tech bubble’s aftermath, and utilities was one of the best-performing during the global financial crisis.

Notes: Calculations are based on the annualized returns over the relevant time periods for the various sectors. The returns of the REIT sector were calculated from monthly Dow Jones U.S. Select REIT Index returns. All other sectors calculated from monthly Standard & Poor’s 500 Index sector returns. Past performance is no guarantee of future returns. The performance of an index is not an exact representation of any particular investment, as you cannot invest directly in an index.
The chart below compares the last two bear markets using a style-box framework with nine categories. During the tech-bubble burst, large-cap growth was the worst-performing sector, while mid- and small-cap value outperformed by comparison. But during the global financial crisis, large-cap growth was the best-performing sector, while large-cap value was the worst-performing.

Challenges for active managers
Active managers, as I noted above, didn’t escape this unpredictability either. The top-performing active managers after the tech-bubble burst were no more likely to stay in the top half during the global financial crisis than end up in the bottom half, or be liquidated or merged.
We found this by taking all surviving funds after the dot-com implosion and bucketing them by performance quartiles. We then looked at how the top-performing quartile of funds performed during the subsequent bear market.2
By comparison, random outcomes would show that each quartile category collected a quarter of the observations. Without even assuming that a majority of the liquidated/merged funds would have been in the bottom quartiles, it’s clear that a given manager’s success in one bear market did not guarantee success in the next.
