S&P 500's Sustained Technical Strength Signals Bullish Momentum
The S&P 500 index closed its tenth consecutive week above its 50-week simple moving average on Friday, March 29, 2024, a streak last observed in the fourth quarter of 1998 during the dot-com boom. This specific technical achievement, occurring with the index at 5,254.35 points, marks a rare confluence of sustained bullish momentum, underscoring the market's robust performance.
Following this milestone, the benchmark index extended its gains by 0.8% to 5,296.50 points in early trading Monday, with trading volume on the New York Stock Exchange up 15% compared to its 30-day average. Investor sentiment, as measured by the CBOE Volatility Index ($VIX), dipped 4.2% to 12.80, signaling reduced near-term market anxiety and a continued risk-on appetite among participants.
Market Impact
The S&P 500's ascent to 5,296.50 points represents a 10.3% year-to-date gain, adding approximately $3.5 trillion to its total market capitalization since January 1. Technology and growth stocks, particularly members of the "Magnificent Seven," have spearheaded this rally, with $NVDA up 85% and $MSFT up 15% over the same period, driving a significant portion of the index's performance.
This consistent outperformance marks the longest weekly closing streak above the 50-week SMA since the 13-week run ending in November 1998, a period that saw the S&P 500 gain an additional 18% over the subsequent year. The current rally has pushed the index's price-to-earnings ratio to 21.5x forward earnings, its highest level since early 2022, indicating a premium valuation.
The strong equity performance has coincided with a retreat in traditional safe-haven assets. Gold futures ($GC=F) fell 1.5% to $2,180 per ounce, while the U.S. Dollar Index ($DXY) strengthened by 0.3% to 104.20, reflecting a broader shift towards riskier assets. Bond yields have also seen upward pressure, with the 10-year Treasury yield ($US10Y) rising 5 basis points to 4.25%, as investors reallocate capital.
What Analysts Are Saying
According to JPMorgan Chase & Co. strategists led by Marko Kolanovic, the technical setup suggests that "momentum traders will continue to drive the market higher, potentially pushing the S&P 500 towards 5,500 by mid-year, fueled by robust corporate earnings and AI-driven productivity gains." They emphasize that strong corporate balance sheets and a resilient economy provide a solid foundation for further appreciation.
However, Bank of America Corp. analysts, referencing similar streaks in the late 1990s, noted that "while initial gains are typical, the market often experiences a significant correction within 12-18 months after such extended technical strength, especially when valuations are stretched." They added that "the current market breadth also remains a concern, with a disproportionate number of gains concentrated in a few mega-cap stocks."
Meanwhile, BlackRock Inc.'s chief investment strategist, Wei Li, offered a more nuanced view, stating, "The current environment is distinct from past cycles due to structural shifts in technology and monetary policy. While historical parallels provide a guide, investors should focus on sector-specific opportunities and quality companies rather than broad market bets, anticipating increased dispersion in returns."
What to Watch
The upcoming Q1 2024 earnings season, beginning mid-April, will be crucial for sustaining the current rally. Investors will scrutinize corporate guidance for signs of continued growth, particularly from technology giants and other high-growth sectors. Any widespread disappointment in earnings or outlooks could challenge the bullish narrative, especially given the S&P 500's current forward P/E of 21.5x.
The Federal Open Market Committee's ($FOMC) next meeting on May 1 is another key event. While rate cuts are widely anticipated later in the year, any hawkish rhetoric or unexpected shifts in dot plot projections could trigger significant market volatility. The market is currently pricing in a 60% chance of a 25 basis point rate cut by June, and any deviation from this expectation could prompt a repricing.
From a technical perspective, key support for the S&P 500 resides at the 5,150 level, corresponding to its 50-day moving average, with stronger support near 5,000 points. On the upside, 5,300 acts as immediate resistance, followed by the psychological 5,400 mark. A sustained break below 5,150 could signal a reversal in the short-term trend, prompting a re-evaluation of market direction.
Investors should also monitor market breadth indicators, such as the percentage of S&P 500 stocks trading above their 200-day moving average. A declining breadth while the index continues to rise could signal a weakening underlying market structure, increasing vulnerability to corrections. The current concentration of gains in the top 10 stocks, which account for over 30% of the index's market cap, poses a significant risk if their performance falters.
