Midyear Market Review

Dimensional Fund Advisors

The first half of 2023 gave investors plenty to process—from banking turmoil to a morphing yield curve to the debt ceiling debate. Those with diversified portfolios of equities and fixed income were in a good position to benefit from both assets’ advances at the year’s midway point, a welcome turn from last year’s broad declines.

The Big Picture

US stocks began 2023 with gains.1 Inflation showed signs of cooling, and the Federal Reserve paused in June after a series of rate increases. Regional banks and their holdings came under increased scrutiny in early March, and several lenders were sold to larger banks as some depositors fled. Around this time, US stocks began a decline, only to resume their ascent weeks later. That rally was led by technology stocks,2 whose surge coincided with increased attention on artificial intelligence and its potential.3 Value stocks and small caps started the year with gains, but growth stocks and large caps overtook them in the second quarter through mid-June.4 The bond market rebounded after one of its worst years in decades.5

Inflation continued to retreat from last year’s four-decade high, with the 12-month rise in US consumer prices falling to 4% in May.6 The reading a year earlier was more than double that. Fed officials paused on raising the benchmark federal funds rate in June after more than a year of increases, but signaled they were leaning toward resuming rate increases if inflation doesn’t cool further. The rapid rise in interest rates left some regional banks, such as Silicon Valley Bank, in precarious financial positions, resulting in three of the four largest bank failures on record.7

A Debt Diversion?

In Washington, politicians debated the US debt ceiling. After much back-and-forth, the president and Congress agreed on a deal to raise the debt limit in June, avoiding the impending possibility of a US default. Amid the discussions, stock and bond markets seemed to take the news in stride. The S&P 5008 was up 15.8% through June 16, bouncing back from a two-year low in October and shifting from bear-market to bull-market mode upon reaching a 20% gain from the prior trough. Historically, US equity returns following sharp downturns have, on average, been positive. A broad market index tracking data from 1926–2022 in the US9 shows that stocks tended to continue to deliver positive returns even after the initial recovery from a bear market, or a decline of 20% (See Exhibit 1.)

A Global Perspective

Among the strongest performers so far in 2023 have been technology stocks, recovering after a poor showing in 2022. The tech-heavy Nasdaq rose 30.8% through mid-June. Much of the stock market’s gain can be attributed to just a handful of companies, led by NVIDIA, which saw strong chip sales as interest in AI built.10

Global stock markets also bounced back after posting their worst year since the financial crisis. Global equities, as measured by the MSCI All Country World Index, rose 14.2% through mid-June. Developed international stocks, as represented by the MSCI World ex USA Index, added 13.0%, while emerging markets lagged, with the MSCI Emerging Markets Index up only 8.8%.

Recent history reminds us that emerging markets can be volatile, but they represent a meaningful piece of the investment opportunity set, accounting for more than 11% of the total global equity market11 and providing potentially valuable diversification for an investor’s portfolio. In recent years, the returns of emerging markets have lagged those of developed markets, with emerging markets underperforming US stocks by over 10 percentage points on an annualized basis from 2012-2021 (see Exhibit 2). While recent returns have been disappointing, it is not uncommon to see periods when the reverse is true. For example, just looking back to the prior 10 years (2002–2011), emerging markets outperformed US stocks by more than 10 percentage points and other developed markets by 8 points on an annualized basis. Over the entire 20-year period (2002–2021), emerging markets posted an annualized compound return of 9.7%, matching the return of US stocks and outperforming other developed markets.

Globally, value stocks and small caps started the year outperforming growth and large cap stocks, respectively, but underperformed across the full period.13 However, it’s important to keep value’s recent performance in context. Last year, value outperformed growth by the largest one-year margin since 2000. That turnaround rewarded investors who remained disciplined during the three-year slump for value that ended in June 2020. Meanwhile, large cap stocks have outpaced small caps so far in 2023. Historically, small caps and value stocks have outperformed over the long term.

Inverted Curve, Rising Yields

US Treasuries rebounded after posting their worst annual return in decades last year. For more than six months, the yield on the 10-year government bond has been lower than that of three-month bills, keeping the yield curve inverted. Despite rising bond prices generally, yields (which fall when prices rise) were higher than they have been for most of the past decade.14

Several questions appear likely to capture investors’ attention for the second half of 2023. What’s ahead for the economy in the US and elsewhere? Will the new bull market charge ahead or take a breath? How long will investor enthusiasm last for all things AI? What investors do know is that markets will continue to quickly process information as it becomes available. A long-term plan, one focused on individual goals and built on confidence in market prices, can put investors in the best place for a good experience, whatever may be in store.
