Growth and value are two investment styles based on fundamental analysis. A growth company typically has promising earnings potential and tends to invest more in future growth rather than dividend payouts, while a value company tends to be more established, with stable growth rates and dividend distributions.

While most market participants are familiar with single-style investment strategies, rotating between growth and value could help enhance return potential. The recently launched S&P 500 Growth Value Rotator Index uses a simple momentum rotation signal to switch between growth and value strategies, and it outperformed single-style benchmarks and the broad equity market with lower risk (see Exhibit 1).

Studies[1], [2] have not shown any strong evidence that one style consistently outperforms the other. If we use the S&P 500 Growth and the S&P 500 Value to represent growth and value stocks, we can see that growth stocks outperformed value stocks 51% of the time, while value stocks produced better returns 49% of the time, both on a total return basis, from January 1995 to July 2019.

The goal of the S&P 500 Growth Value Rotator Index is to take advantage of the two styles. It shifts between growth and value strategies based on the momentum rotational signal, calculated as the 12-month return of the growth or value indices. The strategy is constructed as an index of indices, taking the total returns of the S&P 500 Growth Index and S&P 500 Value as the underlying benchmarks. At the end of each month, if the 12-month return of the S&P 500 Growth is greater than the 12-month return of the S&P 500 Value, the index allocates to the S&P 500 Growth, and vice versa. The existing index selection remains unchanged if the one-year returns of growth stocks and value stocks are the same.

The S&P 500 Growth Value Rotator Index delivered significant outperformance from February 1995 to July 2019, producing an average monthly excess return of 0.15% over the overall stock market, as measured by the S&P 500. In addition, the index outperformed the S&P 500 Growth and the S&P 500 Value by 1.38% and 2.75% on an annualized basis, respectively. The reduced volatility enabled the S&P 500 Growth Value Rotator Index to achieve the highest risk-adjusted return among the individual style indices and the S&P 500 (see Exhibit 1).

The outperformance of the S&P 500 Growth Value Rotator Index was most evident in long-term horizons. In the 10-, 15-, and 20-year periods ending in July 2019, the strategy demonstrated consistent outperformance over the single-style strategies and the broad market, on an absolute and risk-adjusted return basis (see Exhibit 2). Over short-term horizons (the three- and five-year periods), the S&P 500 Growth Value Rotator Index notably outperformed the S&P 500 Value and the S&P 500, while its return slightly underperformed the S&P 500 Growth. This is not surprising since the market has been in an expansion stage in recent years. Furthermore, the S&P 500 Growth Value Rotator Index exhibited the smallest maximum drawdown of 49.73%, compared with 56.82%, 53.40%, and 50.95% for the S&P 500 Value, the S&P 500 Growth, and the S&P 500, respectively.

Through the end of July, equities had netted a nice gain for 2019 (though the picture looks a lot different so far in August). Unusually, the S&P 500 Low Volatility Index^® outperformed in an environment when it has typically lagged its benchmark. (The S&P 500 gained 20.2%, while the low volatility index was up 20.8%, thru July 2019.)

Similar to its last quarterly rebalance, turnover in the low volatility index was limited, with changes taking place following the market close on August 16, 2019. Sector allocations are strikingly similar to the previous rebalance, with Financials, Technology and Utilities adjusting slightly higher while Consumer Discretionary, Health Care and Real Estate scaled back marginally.

The Latest Rebalance for the S&P 500 Low Volatility Index Yielded Minimal Changes

Trailing one-year volatility for S&P 500 sectors, a gauge we use sometimes use to gain insight, barely budged in the last three months. This is consistent across all 10 sectors. It’s therefore not surprising that turnover activity over the last two rebalances is at the lowest annualized level on record.

252-Day Volatility Changed Little Across All S&P 500 Sectors Compared to Three Months Ago

Over the 15-year period ending March 31, 2019, the biggest 25% of active large-cap equity funds managed about 90% of all the assets under management (AUM) held in active large-cap equity funds. This may suggest that investors’ fund selections skew toward larger funds. But is bigger always better? This topic has been widely debated: although larger funds may be able to hire more skilled fund managers and, in return, managers’ successful track records may attract more assets, one could also argue that smaller funds may face less liquidity constraints in security selection and can “move the needle” with relatively small investments.

In this blog, we explore the effect of size—as measured by AUM—on active large-cap equity funds’ performance. Our study shows that, in the large-cap equity fund category, larger funds tended to take more risk and generate higher returns than smaller ones. However, their main advantage lies in higher survival rates over the long run, which contributed to their lower percentage of underperformance relative to the benchmark.

Over the 1-, 5-, 10-, and 15-year horizons, we first rank all long-only active large-cap equity funds by their size at the beginning of the period and divide them into quartiles, with the first quartile being the largest and the fourth being the smallest. We then compare their returns, volatilities, survival rates, and ability to outperform the S&P 500^®. To eliminate the confounding factor of equity capitalization, we limit the universe to large-cap equity funds only. Fund returns are on a net-of-fee basis.

Larger funds were more likely to survive the market cycle than their smaller peers, especially over longer horizons (see Exhibit 1). Among the smallest 25% of funds (fourth quartile) that existed at the beginning of the 15-year study period, only 1 out of 5 survived the entire period compared with a survival rate of over 60% for the largest funds (first quartile) over the same period.

Larger funds also tended to fare better against the broad equity market (see Exhibit 2). For example, in the one-year period ending in March 2019, around a third of first quartile funds beat the S&P 500 compared with only 25% for fourth quartile funds. This difference became more pronounced over longer horizons; the low survival rate among smaller funds helps to explain this result given we assume dead funds underperformed the benchmark. In fact, if we account only for funds that have survived the 15-year period, about 73% of funds in the first quartile and fourth quartile underperformed the benchmark (see Exhibit 3).

We next calculated annualized returns and volatilities of all the surviving funds (see Exhibit 4). On average, larger funds showed higher returns and took higher risk than the smaller funds in the 1-, 5-, and 15-year periods. However, this tendency gradually diminished over longer time horizons: the largest funds generated 30 bps of extra annualized returns compared with the other three groups over the 15-year horizon. The 10-year returns and volatilities indicated that large funds were more conservative than their peers during the 2008 financial crisis and its subsequent recovering period.

The third quartile funds (i.e., the second smallest fund group) showed comparable and sometimes even higher returns than the largest ones. This may help to explain why third quartile funds sometimes performed better against the S&P 500 than the other three groups (see Exhibits 2 and 3). Interestingly, these funds did not take extra risk compared with the largest ones.

Historically, the percentage of dividend payers in Brazil has ranged between 71% and 87%,[1] making it a propitious environment for implementing dividend-focused strategies. The highest-yielding stocks in high-yield strategies often come with greater portfolio volatility,[2] and Brazil is no exception. This blog explores the rationale behind the implementation of a low volatility high dividend strategy in Brazil and its potential benefit.

Low volatility high dividend strategies aim to provide yield at a reasonable risk level. To review the characteristics of high dividend yield stocks in Brazil, we separated dividend payers from the S&P Brazil BMI universe into hypothetical quintiles based on yield. Securities in each quintile are equal weighted and held for 12 months. Our results showed that the securities in Quintile 1 (the highest dividend yielding stocks) had the highest average 12-month holding period returns (see Exhibit 1).

Then, we went through the same exercise but based the quintiles on their 12-month trailing volatility. As shown in Exhibit 2, securities with lower volatility (Quintiles 1 and 2) had higher risk-adjusted returns (0.56 and 0.55, respectively) while securities in the higher volatile buckets (Quintiles 3, 4, and 5) had much lower risk-adjusted returns (0.28, 0.34, and 0.24, respectively).

Our approach to combine high yield with low volatility consisted of two steps. First, we selected the top 50% of stocks with the highest dividend yield; second, from that subset, we selected the top 40% with the lowest volatility stocks.

To demonstrate the possible benefits of our approach, we created three hypothetical portfolios based on the dividend payers of the S&P Brazil BMI and measured their historical returns from Dec. 31, 2007, to June 28, 2019.

1. High Yield portfolio: 50% of stocks with the highest dividend yield of the dividend payers of S&P Brazil BMI.
2. Low Volatility High Yield portfolio: 40% of the lowest volatility stocks selected from the High Yield portfolio.
3. High Volatility High Yield portfolio: 60% of the highest volatility stocks from the High Yield portfolio.

All portfolios were rebalanced in June and December, and all portfolio members were equally weighted.

The results show that over the mid- and long-term periods, the Low Volatility High Yield portfolio outperformed the High Yield and High Volatility High Yield portfolios with less risk, delivering better risk-adjusted returns (see Exhibit 3).

To review how these hypothetical portfolios performed in the most significant down markets, we looked at the three largest drawdowns of the S&P Brazil BMI since Dec. 28, 2007. In all the drawdown periods, the Low Volatility High Yield portfolio outperformed the benchmark and High Yield and High Volatility High Yield portfolios (see Exhibit 4).

Combining low volatility and high dividend yield strategies by using a two-step screening process when constructing a high dividend index could potentially provide better risk-adjusted returns than a high yield strategy, capturing the benefits of high dividend and low volatility strategies.

Consistently outperforming the S&P 500^® is difficult. The S&P Dow Jones Indices SPIVA report shows that less than 18% of funds outperformed the S&P 500 (SPX) over the five-year period ending 12/31/2018. So how is it that the S&P 500 Equal Weight Index (SPEWI), a passive index comprised of the very same 500 stocks, accomplished what so few active managers have been able to do, outperforming the S&P 500 in 13 of 19 years from 2000-2018[1]? And how can understanding the nature of that outperformance yield further portfolio innovation?

Through selling winners and buying losers to parity each quarter, equal-weighting attempts to address a core inefficiency of cap weighted indices, which by definition – systematically over-weight, overvalued companies. While it is impossible to identify ahead of time which companies are the overvalued ones, the index should take the mathematical loss over time.

When viewed through this lens, it’s apparent that exploiting the allocation inefficiency of Cap Weighting through Equal Weighting is only a half measure.

The opposite of “Cold” isn’t “Room Temperature,” it’s “Hot.”

The Reverse Cap Weighted Index (Reverse), which as the name implies – reverses the order of the S&P 500 through weighting by 1/Mkt Cap, takes exploiting that inefficiency one step further. In direct contrast to Cap Weighting, Reverse by definition – systematically over-weights undervalued companies.  More information on Reverse Cap Indexing can be found here. The net result of weighting a portfolio in this manner is effectively a contrarian play within the S&P 500, as the largest companies/industries in SPX would be the lowest weighted within the Reverse Index.

Historically, in environments in which SPEWI outperforms SPX, we would expect Reverse to outperform them both. Conversely, in environments where SPX outperforms SPEWI (as is the case over the last three years) we would expect Reverse to be the worst performing of the three. Below is a chart detailing the performance of the three indices from 12/31/1996 – 6/30/2019.

Consistent with this expectation, just as SPEWI has outperformed SPX with additional volatility, Reverse was the best performing of the three alongside the highest volatility of group. While the total return figure demonstrates the robustness of the outperformance, the below daily 5-year rolling return chart shows the consistency of that outperformance, with Reverse being the highest returning of the three indices in 78% of the observed data points.

This additional return (and the relationship to SPEWI) is partially derived from the higher Size (SMB), Value (HML) and Anti-Momentum (MOM) factor loads expressed in the Reverse Index, relative to the other S&P weighting schemes. Reverse merely places additional load on the factors that drive differentiation between SPEWI and SPX. These findings (as they relate to SPEWI and SPX) are consistent with prior S&P DJI research.[2]

While SPX represents an operationally efficient index, Reverse takes the well understood elements of SPEWI (which exploit the investment inefficiencies of Cap Weighting), one step further and provides a unique contrarian play within the S&P 500 universe.
