What’s the role of indices in constructing and evaluating model portfolios? S&P DJI’s Joseph Nelesen and BlackRock’s Elise Terry explore how indexing is changing the landscape for advisors and their clients and helping a range of market participants build and assess models across the asset class spectrum.

Since the first publication of the S&P Indices Versus Active (SPIVA^®) U.S. Scorecard in 2002, S&P Dow Jones Indices has regularly reported on the relative performance of actively managed funds versus benchmark indices across an increasing number of global fund markets and fund categories.¹

The SPIVA Japan Scorecard has been tracking the performance of active funds offered in Japan since 2014, covering large-, mid- and small-cap segments, as well as international and global equity funds. Over these years, we found that a significant majority of active funds in Japan underperformed their assigned benchmark in each of our reported fund categories. Exhibit 1 summarizes the underperformance rate of active funds in Japan over the 1-, 3-, 5- and 10-year periods ending on Dec. 31, 2023, across different fund categories.

While 2023 marked an epic turnaround for Japanese equities with a reprieve from long-suffering deflation, it was a challenging year for Japanese active managers. 78% of Japanese domestic equity funds (All Japan Equity category) underperformed the broad-based S&P Japan 500 over the full year 2023. Furthermore, over two-thirds of equity funds underperformed their benchmarks in every reported category, posting underperformance rates worse than their 10-year averages in nearly all categories except for the U.S. Equity (see Exhibit 2).

What could explain last year’s misfortune of Japanese active fund managers? Among many possible explanations, we found three market conditions that posed challenges for active managers.

1. Large-cap outperformance: The outperformance of large-cap companies was one of the key market trends in 2023. This was well publicized in the U.S. market with the so-called “Magnificent Seven,” namely Apple, Amazon, Alphabet, Meta, Microsoft, Nvidia and Tesla, which contributed 58% of the S&P 500^®’s return in 2023. Similarly in Japan, the large-cap S&P/TOPIX 150 outperformed the S&P Japan MidSmallCap by 4% in 2023, resulting in increased market concentration (see Exhibit 3). This environment would have worked against active managers who searched for a source of outperformance among smaller, lesser-known names.
   
2. Falling dispersion: Dispersion,² the degree to which stocks differ from the average performance, measures the opportunity set for active managers to outperform through stock selection. Dispersion moved lower globally in 2023, though it remained elevated relative to its history (see Exhibit 4), which points to reduced opportunities for active managers overall.
3. Return distribution: Stating the obvious, when fewer stocks outperform the benchmark, it becomes less likely for managers to find them. In 2023, the percentage of constituents outperforming their benchmark fell well below 50% across domestic and global benchmarks amid a strong market rally. In Japan, the percentage of constituents outperforming the S&P 500 Japan dropped from 58% in 2022 to 44% in 2023 (see Exhibit 5).

Commodity markets remain on top of the asset class leader board with inflation drawing the ire of the Fed and other asset classes. The upside surprise in U.S. inflation spotlights the potential benefits of commodities as a diversification tool. The S&P GSCI, the leading indicator of broad commodity performance, has produced double-digit returns in 2024, currently up 12.8% following the uptick in consumer prices. Gold continues to reach all-time highs, surpassing USD 2,344 per troy ounce while cocoa is the best-performing commodity, nearly tripling over the past year. Both components are included in the S&P GSCI, helping produce a diversified exposure to the broad commodity market. For perspective, bitcoin has captured sizable flow into ETFs, and the S&P Bitcoin Index is “only” up 140%, less than half of what cocoa has done in the same period. The S&P GSCI has benefited from holding gold and cocoa, but oil is the largest component and has delivered the strongest historical sensitivity to inflation. The petroleum sector within the S&P GSCI is up 21.4% YTD, with precious metals up 13.2%. In this post, we review the last half century of commodity performance, which covers inflationary regimes and central bank responses.

Commodities have done well when inflation remains elevated, and the Federal Reserve maintains a defensive posture. Breaking inflation into low, medium and high inflationary environments, commodities have experienced double-digit annual gains when inflation exceeds 2%. The average one-year return when inflation measures between 2% and 4% is 13.3%. Exhibit 1 shows the breakdown by inflationary tiers.

Another way to measure commodity performance is when the Fed maintains a restrictive stance, defined by the Fed Funds Effective Rate exceeding target inflation of 2%. Again, going back the full history of the S&P GSCI to 1970, we measure the annualized returns during such periods and compare that with accommodative environments. The S&P GSCI achieved average annualized returns of 10.6% over the 39 years when the Fed Funds Effective rate was above 2%. This compares favorably to 0.9% average annualized returns during the 16 years the Fed held the effective rate below 2%. We recently covered this in a blog post, and updated the data through April in Exhibit 2.

A broad basket of commodities has historically helped provide diversification and inflation protection. Unlike traditional asset classes such as stocks and bonds, commodities have unique risk and return characteristics that are often uncorrelated with other investments. The S&P GSCI’s 10-year correlation to the S&P 500^® is 0.4, while its correlation to the S&P GSCI Gold component is zero and it has a negative correlation of -0.16 to the S&P U.S. Aggregate Bond Index. Including commodities could help reduce overall volatility and enhance risk-adjusted returns by spreading risk across different asset classes. Additionally, commodities have historically exhibited a positive correlation with inflation, making them a possible hedge against rising prices. As prices for commodities tend to rise during inflationary periods, broad-based commodity indices like the S&P GSCI have demonstrated low correlation to other asset classes as well as positive performance correlation to persistent inflationary environments.
