S&P 500 could see a quiet 15% pullback as bull market wanes

A quiet dip may follow the S&P’s rally, with a 15% correction possible despite muted market signals.

S&P 500 could see a quiet 15% pullback as bull market wanes

The broad U.S. equity index is hovering less than 2% below its all-time peak, while the Dow Jones and Nasdaq linger about 4% under their historic highs. Although price moves appear modest, several market historians argue that the current bull market could be nearing a soft landing rather than a dramatic crash. The prevailing narrative suggests that the final stretch of a bull run often unfolds with a whisper instead of a roar, and many investors may be caught off-guard if they expect a sudden plunge.

Historical fingerprints of bull-market peaks

Data compiled by Ned Davis Research, covering the major turning points since 2000, reveal a stark contrast between the 50-trading-day windows that precede bear-market bottoms and those that precede bull-market tops. In the run-up to market bottoms, the S&P 500 typically experiences a sharp, accelerating decline, while the index remains remarkably flat during the comparable period before past tops. This asymmetry is also evident in the behavior of short-term market timers: on average, they slash equity exposure by 20 percentage points before a bottom, but only nudge it upward by less than four points before a top. The prevailing sentiment leading into a peak is therefore one of exhaustion or indifference not the panic-filled “throwing in the towel” seen at market lows.

What the numbers say today

Current market breadth mirrors the historical pattern of calmness. The VIX, the CBOE’s “fear gauge,” is sitting below its long-term average, indicating that investors are not yet pricing in a spike in volatility. Meanwhile, the S&P 500’s modest 2% distance from its record level does not trigger traditional alarm bells, nor do the roughly 4% gaps for the Dow and Nasdaq. Yet, a closer look at internal sentiment metrics shows that market timers have barely adjusted their equity allocations in the past month, a movement consistent with the flat-trend observed before previous bull-market peaks.

Expert warning of a 10%-15% correction

Hayes Martin, president of the advisory firm Market Extremes, has recently flagged a potential sharp pullback for the S&P 500. In an email circulated earlier this week, Martin highlighted divergences in sentiment extremes and market internals that, in his view, presage a correction in the 10%-15% range. He cautions that the Nasdaq and smaller-cap stocks could suffer even larger declines. Importantly, Martin does not equate this correction with the end of the bull market; rather, he sees it as a healthy reset that often follows the quiet climax of an extended rally.

Investors should therefore brace for a scenario where the index slides roughly 15% over the coming weeks, even though the market’s outward demeanor remains subdued. The key takeaway is that the absence of dramatic sell-offs does not guarantee safety; the historical record shows that the most decisive signals often hide behind a veil of indifference.

While the forecast suggests a notable pullback, it also implies that the broader upward trend may persist beyond the correction. Traders who remain vigilant about sentiment extremes and who monitor the VIX for early spikes will be better positioned to navigate the likely turbulence without being forced to exit positions in panic.
