Goldman Sachs estimates that enthusiasm in the U.S. stock market has climbed to the 86th percentile historically, approaching but not matching the extremes seen during the 2000 dot-com bubble and the 2021 peak. The S&P 500 has surged 15% over the past two months, placing the rally in the 99th percentile of gains since 1980, despite a brief pullback at the end of last week.
This positioning signals that while the rally may still have room to run, risks are building as key indicators move closer to levels associated with past market peaks.
Strong rally backed by earnings, not speculation
According to Goldman Sachs chief U.S. equity strategist Snider, the current uptrend differs from previous late-cycle rallies. Unlike 1999 or 2021, gains are being driven mainly by improved earnings forecasts rather than speculative excess.
Artificial intelligence-linked stocks and momentum trades have risen alongside major indexes, creating a synchronized market advance. The return-to-volatility ratio has approached 4, the highest level in more than 50 years, highlighting the unusual strength of recent gains relative to market fluctuations.
Warning signals begin to emerge
Goldman’s composite sentiment model, which tracks nine indicators, places current conditions above long-term averages but below historical extremes. However, several risk factors are edging higher at the same time:
- speculative trading activity is increasing, with higher options volumes and margin balances
- equity issuance is rising as IPO markets reopen
- growth conditions are softening while cost pressures weigh on margins
- expectations for potential Federal Reserve tightening are building
Although none of these indicators have simultaneously reached critical levels, their collective movement suggests the market is entering a more fragile phase.
Market breadth narrows, volatility reappears
Participation in the rally is beginning to thin. Only 53.67% of S&P 500 stocks are trading above their 50-day moving average, signaling that gains are being driven by a smaller group of names. Historically, further declines in this measure have preceded broader slowdowns in momentum.
Volatility has also returned. The CBOE Volatility Index (VIX) jumped nearly 40% in a single session to 21.51 last week, following an extended period of calm. The move reflects growing sensitivity to potential shocks as valuations stretch.
Policy uncertainty and rising supply add pressure
The Federal Reserve is maintaining its policy rate in the 3.50% to 3.75% range, balancing inflation risks against signs of a cooling labor market. While immediate rate hikes are not expected, markets are increasingly pricing in the possibility of future tightening, making upcoming economic data critical.
At the same time, capital markets activity is accelerating. A total of 68 IPOs have launched this year, raising $34.2 billion, a sharp increase of more than 160% from a year earlier. This resurgence adds new supply to equity markets, potentially diverting capital from existing stocks.
Sentiment remains mixed among traders
Despite strong index performance, sentiment among individual traders remains cautious. Data from the American Association of Individual Investors shows bearish sentiment has stayed above its historical average for 17 consecutive weeks. The bull-bear spread remains negative at -0.7%, well below the long-term average of 6.5%.
This divergence suggests that broad-based optimism has yet to fully take hold, leaving room for sentiment to shift in either direction.
Outlook: strong foundation, tightening window
Goldman Sachs concludes that the current rally is entering a zone historically linked to elevated enthusiasm but has not yet reached extreme levels. The reliance on improving earnings provides a more stable foundation than past speculative cycles.
However, narrowing market breadth, rising volatility, and building macro risks indicate that conditions are becoming less forgiving. While the uptrend may persist, the margin for stability is shrinking as multiple warning signs begin to align.
