Equity markets continued to rise in the second quarter of the year, albeit more slowly than in the first quarter. The MSCI World Index gained 6.8% over the quarter, U.S. equities rose 8.6% and European equities rose 2.3%. The performance drivers remained the same with mega caps, particularly tech mega caps, behind the bulk of the performance.

This installment of the WisdomTree Quarterly Equity Factor Review aims to shed some light on how equity factors behaved in this complicated quarter, and how this may have impacted investors’ portfolios.

• In a sharp reversal from 2022, growth stocks continued to lead in developed market equities
• The best factors for 2022 continued to suffer as well, with value and high dividends posting sharp underperformance
• In emerging markets, the picture is quite different, with value and size leading the way

Year-to-date equity gains have been concentrated in a handful of expensive names. Equity markets are currently pricing in for a perfect outcome, with inflation coming down nicely, growth remaining resilient and unemployment staying low. Uncertainty remains very high and there are potential opportunities to be found among the laggards, including in the defensive, or cheaper, side of the markets.

Performance in Focus: Reverse 2022

The second quarter saw a continuation of the trend that started in Q1. Big tech stocks benefitted from the positive sentiment around generative AI and AI in general, with stocks like Nvidia posting returns of 52.3% during the quarter (after gaining 90% in Q1). Equity markets overall were buoyed by optimism about the trajectory of U.S. inflation and by unemployment remaining surprisingly resilient. Overall, 2023 continues to look like the anti-2022: growth stocks are up, Bitcoin is up (83.7% YTD), and high dividend and value are down. This sharp turnaround highlights, once again, the importance of diversification.

The year remains a difficult period for factor investing in developed markets:

• Growth stocks performed the best in Q2, outperforming by 3.6% globally and by 5.2% in the U.S.
• Quality continued to be the second-best factor for the quarter in developed markets, in particular when loading on more expensive tech stocks
• In developed markets, other factors like value, high dividend and min volatility all suffered from the change in regimes compared to last year
• As a testament to the sharp reversal in sentiment/performance, momentum posted the worst performance year-to-date globally and in the U.S., as it could not adjust to the rapid change
• In emerging markets, size and value dominated but most factors were able to produce outperformance over the quarter

2023 Has Been Very Consistent Factor-wise

Looking back at the full six months, the picture is quite coherent. Growth outperformed in five out of six months, underperforming only by -0.2% in April. It outperformed by more than 2% in half the months (January, March and May). High dividend underperformed almost every month with a 0.1% outperformance in April, saving it from a “perfect” streak.

A Very Concentrated Recovery

Looking at the performance of the S&P 500 year-to-date (+16.6%), almost three-quarters of it has been created by the 10 biggest stocks in the index. Those stocks only represent 27% of the weight in the index. Figure 3 shows, for each stock, its weight and how much it contributed to the index’s half-year performance. Every stock that sits above the red line contributed more than its weight would suggest. Clearly, the eight tech stocks in the S&P 500 top 10 have all contributed very positively, explaining most of the performance of the index.

Valuations Continued to Increase in Q1

In Q2 2023, markets continued to get more expensive on the back of good performance. However, this average increase hides discrepancies. Growth got more expensive quickly and is showing a price-to-earnings ratio of more than 30 in the U.S. However, value remains very cheap at 7.2 in the U.S. and 9.4 for developed markets. This is also the case for high dividends with low double-digit valuations. Momentum’s valuation is rising fast, a clear sign that the basket is shifting away from cheap value to expensive growth. The next few months will tell us if it was too late.

Looking forward to the rest of 2023, it feels like markets are pricing in for a perfect outcome with inflation coming down nicely, growth remaining resilient and unemployment staying low. Overall uncertainty remains high and interest rate volatility continues to be elevated across the world. U.S. optimism could unravel quickly.

With year-to-date gains concentrated in a handful of expensive names, there are potential opportunities in some of the laggards, including in the defensive, or cheaper, side of the markets.
