A presentation to: Is Active Equity Management on Permanent or Temporary Disability? Atlantic Connection Conference Tina Byles Williams, CIO and CEO FIS Group July 10, 2013
Background and Key Research Questions • As of December 31, 2012, the S&P 500 Index more than doubled since its March 2009 bottom. • Active Large Cap managers, as a class, underperformed the market benchmark with a tenacity that is troubling leading many investors to passive implementation of their U.S. Equity portfolios. • Our research evaluates the following key questions: • Are there structural factors, in either the selection methods or preferences of institutional investors, that set them up for disappointing active manager results? • Are actively managed U.S. Large Cap strategies no longer a viable option due to structural changes in the market? Or, are these changes cyclical in nature? • Specifically, did the positive relationship between Active Share and excess return observed in prior academic studies change for U.S. Equity Large Cap managers in the post-crash era, and if so, what variables led to the change?
First Problem – Frequently Used Quantitative Metrics for Manager Skill May Be Setting Investors Up For Failure • The best measures of manager skill, are bothpredictive and persistent. • Commonly used manager skill metrics, such as Alpha and Information Ratio (Institutional Investors), and Morningstar ratings (Retail Investors) are highly susceptible to mean reversion (i.e., the top percentile in year one has an insignificant relationship to the top percentile over longer periods, such as 5 years).

Second Problem: Industry Consolidation Will Likely Lead to More Mediocre Alpha Generation • The investment management industry has been consolidating: • In 1991, the top ten asset managers managed less than 21% of tax exempt assets managed by the top 500 firms. • At year end 2012, the share managed by the top ten jumped to 44%. The top 100 managers (lowest AUM of $14.5 billion) managed 87% of tax-exempt assets. • Several independent studies suggest that scale can often decrease alpha generated by active managers.

Measurement of Skill as Defined by Persistence of Wins from Season to Season Skill Chess Tennis Baseball Investments Luck Football • Highly skilled activities characterized by greater dependence on individual skill and effort. Outcome for activities dominated by luck is highly impacted by multiple factors and other players. • Highly skilled activities demonstrate persistence (think of Serena Williams and Roger Federer vs. Manuel Cabrera from Detroit Tigers who won the triple crown), • Highly skilled activities don’t require a large sample size (or no. of times player plays) whereas activities dominated by luck require a large sample size to discern skill. • Highly skilled activities result in a wide variance between best and worst players. • Highly skilled activities, limited mean reversion. Activities dominated by luck, complete reversion to the mean.
Enter Active Share • Represents the percentage of a portfolio’s holdings which is different from its benchmark based on a scale between 0 and 100; with 0 suggesting no difference from the holdings of the benchmark and 100 suggesting no similarity with the benchmark. • Based on Yale and NYU professors Cremers and Petajisto study of 904 U.S. mutual funds’ performance between 1980 and 2003 and concluded that, on average, performance is positively correlated with the degree of active management as measured by Active Share. 1 • They demonstrated that funds in the highest quintile of Active Share outperformed their benchmarks annually by 1.39%, net of fees and expenses. In contrast, non-index funds with the lowest Active Share score underperformed their benchmark by 1.41% annually, net of fees and expenses. • Active Share does not necessarily cause or connote skill; it simply measures difference from the manager’s benchmark. • However, since it is directly driven by a manager’s investment policy, there is substantial inter-temporal persistence. Maubisson’s research found a .86 correlation among the Active Share of 1500 mutual funds between 2007 and 2012.2 • Therefore, if a manager has skill, then Active Share amplifies both the magnitude of their performance and the persistence through which it is expressed. 1Petajisto, Antii and Cremers, Martijin, How Active is Your Fund Manager?

Could Studies That Purport to Show the Randomness of Active Management Alpha Not Also Reflect These Trends? • Use of poor predictors of future performance (such as Universe rankings, Alpha and IR). • They typically don’t distinguish by AUM, but AUM can impact Active Share and performance. • They typically don’t distinguish between high and low Active Share managers (i.e., truly active vs. closet indexers, that have historically underperformed high Active Share managers). • They may in part reflect the decline in Active Share, particularly among U.S. large cap funds: • During the 1990s, the percentage of U.S. Equity mutual funds with high active share dropped by over 70% and now stands at around 20%. • 1990s associated with periods of enhanced risk control/portfolio constraints, such as the popularization of nine style box framework (large/mid/small by growth/value/core).

Rolling Performance of Active Managers Consistent with Results of Active Share Regressions Rolling 12-Quarter Universe Analysis December 31, 1992 to September 30, 2012 | Wilshire Manager Defined Universe • For Non-U.S. and Small Cap managers, there is more evidence of relative performance persistence. • For U.S. Equity Large Cap managers relative performance evidences cyclicality with each cycle averaging 5 to 6 years. The current cycle of underperformance began in 2009. During intense market downturns (2001 and 2008), the benchmark underperformed.

Factors That Primarily Impacted Active U.S. Equity Large Cap Managers’ Relative Performance Source: Byles Williams, Is Active Equity Management Alpha on Permanent or Temporary Disability?, April 2013 & FIS Group Model Estimates.
Normalization of Intra-market U.S. Stock Correlations Key to Large Cap Manager Outperformance European and U.S. Economic Policy Uncertainty Indices: 1/1997 to 11/2012 • Correlation is mean reverting – anchored by the volatility of stock volatility. The primary catalysts for mean reversion are reductions in down-market deviation and Economic Uncertainty. • Globalization and the global deleveraging cycle have engendered more interconnected and fragile economies. Although uncertainty has decreased since mid-2012, heightened uncertainty likely to remain. • The relationship between Economic Uncertainty and Correlation is non-linear. Therefore, decreases in economic policy uncertainty have a more muted impact than increases.
Conclusion • The disappointing results exhibited in studies on the performance of active managers may in part reflect poor quantitative selection criteria that are highly susceptible to mean reversion. • The inexorable consolidation within the asset management industry will likely lead to more mediocre results. • The post-crisis period has been dominated by macro-economic variables that impaired the performance of Large Cap managers. • Large Cap stocks’ greater exposure to systemic market risks made them more vulnerable to deleterious changes in the macro-economic regime. • Because Small Cap and Non-U.S. managers are less exposed to systematic risks (and reflect more non-systematic or idiosyncratic risk factors), their alpha has been more persistent through various macro cycles. • The predominance of macro factors such as Correlations (that are in turn driven by Economic Uncertainty) and monetary accommodation would suggest that their normalization could lead to improved performance for Large Cap managers. • Although Economic Uncertainty has declined since mid 2012, the ongoing global deleveraging cycle will likely prolong the normalization of the current macro regime.
