For decades, stock pickers have tried to outperform the broader market, yet most have consistently fallen short. Over a ten-year period, roughly 80% to 90% of U.S. large-cap mutual funds have underperformed the S&P 500 after accounting for fees. This persistent gap has pushed investors and asset managers to rethink what “alpha” really means. Rather than attempting to beat a single equity index, some are now focusing on generating excess returns through smarter portfolio construction that spans multiple asset classes, from cash and bonds to commodities.

This broader, more flexible approach is gaining traction among major asset managers such as Pimco and State Street Investment Management. Both firms recently shared their perspectives on CNBC’s ETF Edge, emphasizing opportunities for differentiated returns beyond traditional U.S. large-cap stocks.

Importantly, these firms are not predicting the end of U.S. equity strength. Instead, they argue that heightened volatility driven by geopolitical tensions, uneven global growth, and diverging central bank policies has made diversification more valuable than it has been in years. In such an environment, modest portfolio adjustments could meaningfully enhance returns in 2026.

Matthew Bartolini, global head of research strategists at State Street Investment Management, pointed out that 2025 marked the first year since 2019 in which stocks, bonds, gold, and commodities all outperformed cash. According to him, this creates fertile ground for what he calls “portfolio construction alpha,” which comes from thoughtful asset allocation rather than trying to outperform an index directly.

One of the most overlooked starting points, he said, is cash itself. A significant amount of investor capital remains parked in cash-equivalent vehicles. Moving even a portion of that capital into higher-yielding alternatives can already be considered a form of alpha generation.

Jerome Schneider, head of short-term portfolio management at Pimco, echoed that sentiment. He described cash management as the foundation of portfolio strategy, noting that enhanced cash solutions can deliver returns that are 1% to 2% higher than traditional cash accounts without dramatically increasing risk.

Beyond cash, Schneider believes bonds may offer a more reliable source of incremental returns than equities at this stage of the cycle. Rather than attempting to outperform the S&P 500, investors can seek value through fixed income strategies. Pimco has recently launched an actively managed ETF that pairs passive exposure to the S&P 500 with active bond management, reflecting this philosophy.

Looking ahead to 2026, Schneider expects overall economic growth to remain solid, though uneven across different sectors and income groups. He emphasized the importance of global diversification, particularly as monetary policies diverge more sharply than they have in decades. Countries such as Canada, Japan, Australia, and the United Kingdom are moving along distinct policy paths, creating relative-value opportunities for investors willing to look beyond U.S. borders.

Schneider also encouraged investors to broaden their definition of fixed income. Instead of concentrating solely on corporate bonds late in the economic cycle, he highlighted securitized assets like agency mortgages as potential sources of stability and yield. He cautioned that rigid, passive benchmarks may limit flexibility at a time when valuations and geopolitical risks are elevated. While active bond strategies have historically performed better than active equity strategies in many cases, he acknowledged that performance varies significantly across fixed income categories.

Bartolini stressed that improving portfolio design does not require abandoning U.S. markets, despite periodic fears of a so-called “sell America” trade driven by political uncertainty. Rather, it means adding complementary asset classes to reduce concentration risk. State Street’s multi-asset ETF developed with Bridgewater Associates reflects this idea by investing across global equities, bonds, inflation-linked securities, and commodities.

According to Bartolini, many portfolios remain heavily tilted toward U.S. equities, often at the expense of assets that provide inflation protection or diversification. He noted a structural underallocation to real assets such as commodities and inflation-linked bonds, despite their strong recent performance.

Gold, for example, delivered its best annual return since 1979 last year, while a majority of international stock markets outperformed U.S. equities. Precious metals including gold, silver, and platinum recently reached record highs. These trends suggest that investors with portfolios dominated by U.S. stocks may benefit from blending in additional asset classes rather than relying on a single source of returns.

Bartolini emphasized that the past 15 years have made U.S. equities one of the most successful investment trades in history, and he does not anticipate a sudden mass exit from U.S. assets. However, he argued that allocating as much as 80% of a portfolio to one country’s stock market runs counter to the principles of balance and diversification.

Instead of drastic risk reduction, he advocates gradual rotation. For example, reducing U.S. large-cap exposure from 80% to 70% or 75% can meaningfully improve diversification without abandoning growth potential. He also pointed to renewed interest in small-cap stocks during the second half of 2025, driven by expectations of easier monetary policy and increased fiscal support.

Since mid-2025, small-cap equities have outperformed large-cap stocks, supported by improving earnings forecasts for 2026. The Russell 2000 Index has reached record highs and posted gains of nearly 9% this year, while the S&P 500 has remained largely flat. Small-cap stocks have outpaced large caps for fourteen consecutive trading sessions, marking the longest such streak since 1996. Over the past six months, small caps have delivered roughly double the returns of their large-cap counterparts.

Taken together, these trends suggest that alpha in the coming years may be less about picking the next winning stock and more about constructing resilient, diversified portfolios that adapt to a changing global landscape.
