The 2023 rally continued in the first quarter of 2024, as a positive combination of stable economic growth, falling inflation, impending Fed rate cuts, and ever-growing enthusiasm towards artificial intelligence (AI) propelled stocks higher. The S&P 500 rose above 5,000 for the first time and hit new all-time highs.
The year began with a modest uptick in volatility, as traders and investors initially booked profits following the strong 2023 gains. However, those initially small declines intensified shortly after the start of the year when the December Consumer Price Index, an important inflation indicator, declined less than expected. That reading challenged the idea that inflation was quickly falling towards the Fed’s 2.0% target and caused investors to delay the expected date of the first Fed rate cut, as expectations for that first cut moved from March to June. Fears of potentially higher-than-expected rates pushed stocks temporarily into negative territory early in January. However, the declines didn’t last. First, fourth-quarter corporate earnings were again better than feared, and that helped stocks recover from those early declines. Then, in late January, the Federal Reserve clearly signaled that rate hikes were over and strongly hinted that rate cuts would occur in the coming months. Investors seized on that positive message, and the S&P 500 hit a new all-time high late last month. It finished with a modest gain, up 1.59%.
The rally continued and accelerated in February as fears of a potential rebound in inflation subsided. Inflation metrics released in February largely met expectations and did not imply that inflation was reaccelerating. As such, investor expectations for a June rate cut were strengthened, which helped stocks extend their year-to-date gains. Then, on February 21st, Nvidia, the semiconductor company at the heart of the AI boom, posted much stronger-than-expected earnings and guidance. Those results further fueled investors’ AI enthusiasm, and large-cap tech stocks powered the S&P 500 higher into month-end as the index hit a new record high above 5,000. The benchmark domestic index gained 5.34% in February.
The quarter's final month saw even more gains, aided by familiar factors such as solid economic growth, generally as-expected inflation data, AI enthusiasm, and bullish Fed guidance. Broadly speaking, economic and inflation data largely met expectations in March and continued to point towards stable growth and (slowly) falling inflation. Then, in mid-March, updated Federal Reserve interest rate projections still pointed towards three rate cuts in 2024, further reinforcing investor expectations for a June rate cut. Those positive factors, combined with additional strong AI-related earnings reports (this time from Micron) pushed markets broadly higher as the S&P 500 crossed 5,200 for the first time late in the month and ended March with strong gains.
The 2023 rally continued and accelerated in the first quarter of 2024 thanks to positive news flow that implied stable growth (no recession), still-falling inflation, looming Fed rate cuts, and continued AI enthusiasm. Those factors propelled the S&P 500 to new all-time highs.
First Quarter Review
The first quarter of 2024 reflected a much more evenly distributed rally than the fourth quarter of 2023, where tech and tech-aligned sectors handily outperformed the rest of the markets. Over the past three months, markets have seen broad gains distributed more equitably amongst various sectors and industries.
However, while the rally in stocks broadened in the first quarter, that did not benefit small caps as they were some of the notable laggards over the past three months. Small caps registered a positive return for the first quarter but lagged large caps as concerns about stubbornly high interest rates weighed on small caps, as they are more sensitive to higher funding costs and slowing growth.
From an investment style standpoint, growth once again outperformed value in the first quarter, but the margin was much closer than last year, as both investment styles logged strong quarterly returns. Continued heightened AI enthusiasm was the main reason for the modest growth outperformance over the past three months, as large-cap tech stocks again saw strong rallies in Q1.
As mentioned, gains were broad on a sector level as 10 of the 11 S&P 500 sectors finished the first quarter with a positive return. Unlike 2023, however, tech and tech-aligned sectors didn’t substantially outperform. To that point, the best-performing sectors in the market in the first quarter were communication services, financials, energy, and industrials. That sector mix reflected the influences of AI enthusiasm, strong financial stock guidance, solid U.S. economic data, and rising optimism toward a rebound in Chinese economic growth. The diversified gains demonstrated that the Q1 rally was driven by a more varied set of influences beyond just AI enthusiasm.
Turning to the laggards, the only S&P 500 sector to log a negative return for the first quarter was the real estate sector, as it continues to be weighed down by concerns about the health of the commercial real estate market. Specifically, terrible quarterly earnings from New York Community Bank reminded investors of the sustained weakness in the commercial real estate market, which weighed on the real estate space. Consumer discretionary also lagged and registered only a slightly positive return as numerous retailers warned about a potential slowing of consumer spending during the first quarter (this is something to monitor as we begin the second quarter).

Internationally, foreign markets posted solid quarterly gains but underperformed the S&P 500. Looking deeper, foreign developed markets outperformed emerging markets in Q1 thanks to better-than-expected economic data and as expectations rose for early summer rate cuts from the European Central Bank and Bank of England. Emerging markets, meanwhile, logged only slightly positive returns in Q1 and solidly underperformed the S&P 500 thanks to mixed Chinese economic data and a lack of substantial Chinese economic stimulus early in the quarter.

Commodities saw strong gains in the first quarter thanks to still-elevated geopolitical tensions, a weaker U.S. dollar and smaller-than-expected declines in inflation. Oil rallied sharply in Q1 thanks to late-quarter optimism for an acceleration in Chinese economic growth, combined with an increase in geopolitical tensions following the continued attacks on commercial ships in the Red Sea, along with an increase in Russian attacks on Ukrainian energy infrastructure. Gold hit a new all-time high in the first quarter, meanwhile, and logged solidly positive returns thanks to the aforementioned buoyant inflation data and a weaker U.S. dollar.

Switching to fixed-income markets, the leading bond benchmark (Bloomberg Barclays US Aggregate Bond Index) realized a slightly negative return for the first quarter of 2024. Disappointing inflation readings were the primary reason for the weakness in bonds as they delayed the expected start of Fed rate cuts from March until June and caused bond investors to consider that rates may be higher than previously expected over the medium and longer term.
Looking deeper into the fixed-income markets, longer-duration bonds underperformed those with shorter durations. That performance gap was due to the slower-than-expected decline in inflation. While it won’t materially delay the start of Fed rate cuts, it does threaten to keep rates “higher for longer,” which is a bigger negative for longer-dated debt.
Turning to the corporate bond market, higher-yielding but lower-quality “junk” bonds outperformed investment grade debt as looming Fed rate cuts and buoyant inflation, amidst stable economic growth, led bond investors to “reach” for more yield in the riskier parts of the credit spectrum.

Second Quarter Market Outlook
We begin the second quarter amid a positive macroeconomic environment as growth appears stable, inflation is still falling, the Fed will likely deliver the first rate cut in four years, and AI enthusiasm keeps earnings estimates high. But while this is undoubtedly a favorable setup, the strong rally of the last six months has left the S&P 500 at previously historically unsustainable valuations while investor and analyst sentiment is very bullish and, potentially, complacent. So, while the outlook is currently positive, it’s essential we continue to monitor the macroeconomic horizon for risks because at current stretched valuations and with sentiment very bullish, the market is vulnerable to a negative surprise.
Specifically, while it’s true that economic growth has remained resilient in the face of higher rates, some data is pointing to a loss of momentum. Retail sales missed expectations in January and February, while the unemployment rate jumped to the highest since 2022 during the first quarter. Neither number warrants concern about the current economy, but both serve as a reminder to watch data closely as a continued economic expansion is not guaranteed.
The scourge of Inflation, meanwhile, is still retreating, but the pace of that decline has slowed meaningfully. Core CPI, one of the Fed’s preferred measures of inflation, has barely declined over the past several months as it sat at 4.0% y/y in October and in February was just 3.8% y/y. Meanwhile, other anecdotal inflation indicators have hinted at a rebound in prices. If inflation bounces back, that will reduce the number of Fed rate cuts in 2024, and that disappointment could pressure stocks and bonds.
To that point, markets fully expect a June rate cut from the Fed and three rate cuts in 2024, and that assumption was central to the first-quarter rally. However, those rate cuts are not guaranteed, and if the Fed does not cut as aggressively as markets expect, that will result in disappointment and a potential decline in stocks and bonds.
Finally, investor enthusiasm towards the potential for artificial intelligence remains a critical part of the bull market, and strong earnings from Nvidia in February furthered investors’ hopes that AI integration will lead to a profitability and earnings boom, not just for tech companies but for the entire market. However, that’s also not guaranteed, and so far, AI integration has produced a lot of flashy headlines but not a lot of profit maximization for non-tech industries. If AI fails to boost profits and demand declines broadly, that will be a significant negative for this market.
The bottom line is that positive fundamentals currently support this historic rally. But I cannot let the currently positive setup blind me to risks, and that’s why, while I am pleased with the market performance, I am also focused on managing both reward and risk in portfolios because, despite the strong performance, this market remains vulnerable to negative news.
