This holiday season has investors in the U.S. stock market eagerly awaiting the potential for what is often dubbed the “Santa Claus Rally.” Historically, this phenomenon refers to a bullish trend that typically unfolds in the final five trading days of the year, extending into the first two trading days of January. Coined by stock trader and author Yale Hirsch, this phenomenon indicates a favorable period for market performance, characterized by significant gains and an increased likelihood for upward movement compared to other times of the year.

Over the past seventy years, the S&P 500 has reportedly seen an average gain of about 1.3% during these seven days, with a striking 78% probability of a positive performance. The excitement builds as Christmas approaches, culminating in a wait for the rally to commence—this year’s festivities begin on Christmas Eve, December 24, and conclude on January 3, 2024.

But can this year’s "Santa Claus Rally" truly manifest amidst current market conditions? There appears to be a divide among analysts and investors regarding the likelihood of a successful rally this year. Despite the historical trend suggesting a seasonal uptick in stock performance, recent market volatility has left many wary. Last week, the Federal Reserve's surprise hawkish stance on interest rates caught many off guard, leading to a substantial decline in the S&P 500, marking its largest single-day drop since August.

Under the surface, the market appears fragile, with eight of the eleven sectors within the S&P 500 showing negative movement for December thus far. Moreover, the equally weighted S&P 500 index has pulled back by 7% from its recent high—a sign of underlying weakness that has market participants on edge. Matt Maley, chief market strategist at Miller Tabak, warns of another lurking concern: the relentless rise in U.S. Treasury bond yields. The 10-year Treasury yield, often viewed as a global benchmark for asset pricing, recently reached its highest level in seven months, hovering around the 4.6% mark. This upward drift in yields places additional pressure on equity valuations.

The current forward price-to-earnings ratio for the S&P 500 stands at 21.6 times, significantly above the historical average of 15.8, creating a challenging backdrop for stocks as bond yields rise. Maley points out that as the year draws to a close, investors must face the reality that stock valuations are exceedingly high and that the Federal Reserve’s policies may not be as accommodative as many have hoped.

Amidst this uncertainty, optimism has not vanished entirely from Wall Street. In a recent report from Ned Davis Research, analyst London Stockton noted that while the stock market has been lackluster leading up to Christmas this year, this could serve as a precursor for a solid rebound after the holiday. The team at Ned Davis observed that historically, when the stock market performs poorly in the days leading up to Christmas, it often sees a significant uptick in the following five trading days. Stockton noted that despite the S&P 500’s roughly 2% drop last week, such situations have led to average returns of 2% in the post-holiday period.

Beyond seasonal trends, other factors hint at the potential for a market rebound before the new year. Indicators maintained by Ned Davis suggest that the U.S. market entered a short-term oversold territory. Furthermore, a sentiment analysis of investor attitudes reveals a notable decrease in optimism, which could imply that a significant amount of liquidity is sitting on the sidelines. Should the market show signs of recovery, these funds are likely to flow back in, potentially driving stock prices higher.

Chuck Carlson, CEO of Horizon Investment Services, echoed these sentiments, stating that the recent pullback in U.S. stocks could have a constructive effect, alleviating some of the bubbling exuberance that has characterized the market. While Carlson is positioning for a rebound, he also cautioned that further declines could pose a greater risk to bullish trends.

For seasoned traders, the implications of the "Santa Claus Rally" extend beyond mere yearly gains; there is a widely held belief that the performance of the market during this period—including the first five trading days of January and overall January trends—serves as a precursor for the markets' trajectory throughout the rest of the year. Historical records show that when all three periods display positive performance, there is a compelling 90% chance that the coming year will conclude with rising stock prices.

Conversely, if the "Santa Claus Rally" fails to materialize, it could signal troubling times ahead. Market declines during this timeframe have foreshadowed significant economic downturns, as evidenced by the palpable drops seen in 1999 and 2007, the years culminating in the dot-com bubble and the subsequent financial crisis. However, it is essential to recognize that these signals are not foolproof; last year, for example, the S&P 500 actually experienced a 0.9% drop during the "Santa Claus Rally" without this negatively impacting the index's remarkable 24% gain throughout the year.

As investors await this year’s “Santa Claus Rally,” they are reminded of market history and the contrasting patterns of gains and losses that circulate every December. The ultimate outcome remains uncertain, but the anticipation of seasonal patterns and economic indicators continues to drive valuable discussions on Wall Street.
