Equity markets are on track for a strong finish to the year, powered by mega-cap growth stocks — the equity MVPs of 2023. Continued strong earnings growth from these businesses, combined with an easing interest-rate regime, could help the S&P 500 Index grind through 5,000 in 2024. Along with these positive trends, however, there is enough uncertainty to make a more range-bound market possible. Lingering concerns about inflation, the labor market, or recession could stifle earnings growth.

In terms of valuation, rising interest rates put a lid on price/earnings multiples over the past year as bonds became more competitive with stocks. However, the recent retreat in the 10-year U.S. Treasury yield could support growth multiples going forward. Much of this year’s market strength was concentrated in a narrow cohort of stocks. But these companies — high-quality businesses with above-average organic growth rates, high returns, strong cash flow, and resilient balance sheets — are deserving of higher p/e multiples.

We don’t know what 2024 will deliver in terms of inflation, interest rates, bond yields, or growth and value performance. We do know that, as active managers, we can focus on delivering consistent benchmark outperformance regardless of the market environment.

Seeking a smooth performance journey

With equity portfolios, strong long-term returns come in many forms. Some are the result of steady, consistent performance year after year. Others take investors on a wilder ride. It’s likely most investors prefer the smoother journey. And this, we believe, can be achieved with stock-driven portfolios that are less vulnerable to style shifts or other causes of market volatility. A portfolio that leans too heavily toward a particular style, sector, or macro view can result in greater fluctuations, sudden sharp downturns, or prolonged periods of underperformance.

Instead, we prefer a “diversified alpha” approach that seeks to avoid performance extremes. We use a stock-driven — rather than style-driven — process that gives us the chance to outperform our benchmarks in all market environments, regardless of whether indexes are rising or falling, or growth or value is leading. We don’t take outsized bets on factors such as sector, style, or company size. Rather, we build portfolios one stock at a time, based on company-specific fundamentals. The goal is to create a portfolio of unique insights. Not every holding will outperform at the same time, but in aggregate, a broad and diverse mix of modestly sized uncorrelated holdings offers greater potential for consistent returns over time — that smoother performance journey.

This approach can also reduce a portfolio’s tracking error, which measures the consistency of its performance relative to its benchmark. Since we do not invest with a focus on common factors such as style or company size, our portfolios are less exposed to the risks associated with them, which all else equal, dampens tracking errors. But we believe the type of risk we are taking — with the emphasis on stock-specific risk — has the potential to deliver higher information ratios.

The value in avoiding performance extremes

In analyzing our approach, we looked at Lipper rankings of four Putnam equity funds since 2014. Their solid 10-year rankings come from a history of moderate and consistent annual performance. By avoiding performance extremes, three of the funds were in the top half of their peer groups 80% of the time, and Putnam Large Cap Growth landed in the top half 90% of the time. We also found that not all competitors’ funds with strong 10-year rankings have offered a smooth ride. Many delivered outsized one-year results and then struggled against style headwinds.

We also looked at above-median performance for all Morningstar active diversified equity funds. Over the past 10 calendar years, 85% of Putnam funds beat their peer group median for six or more of those years. This puts Putnam at number one in this category versus other fund family competitors. Only 46% of peer funds accomplished this.

Plotting a steadier course by avoiding a strong style bias

We looked at all funds that were in the top quintile of the Lipper U.S. Large Core universe for the 10 years ended 12/31/22. While these funds all delivered strong performance over the long term, those with a notable style bias tended to fluctuate more, testing investors’ conviction in the funds with rougher performance rides. Those with neutral style sensitivity, including Putnam Research Fund, offered much more consistent performance.

An unwavering focus on our active strategies

We are closing out a year of surprises in the financial markets — a robust and resilient U.S. economy, a sharp rally in mega-cap growth stocks, and unprecedented excitement around artificial intelligence, to name a few. But surprises are not the goal when managing portfolios for investors. We look forward to seeking a smooth and better-than-index performance journey for investors in the coming year.
