Goldman Trader Warns of a 'Stealth Bear Market' - Why 60% of S&P 500 Stocks Are Already Down 20%+ While the Index Sits Just 3% From Its High

What Happened

Wall Street got a new, uncomfortable number this month. Bobby Molavi, the Goldman Sachs trader who heads the firm's EMEA equity execution desk, used a client note to describe the current market as a "hidden bear market" - or, as other outlets picking up the note have called it, a "stealth bear market." His point was simple but jarring: the S&P 500 itself sits only about 3% below the record high it set in early October, yet roughly 60% of the individual stocks that make up that index have each fallen more than 20% from their own 52-week highs - the textbook definition of an individual bear market. Looked at purely through the index, this reads as a mild, healthy pullback. Looked at stock by stock, well over half the index has already collapsed into bear-market territory.

Molavi pinned the gap on the mechanics of the AI investment boom itself. Hyperscalers' capital spending on data centers and AI infrastructure has been lifting the suppliers on the receiving end of that spending - chipmakers, cloud providers, power and cooling vendors - while simultaneously dragging down the stocks of the hyperscalers writing the checks, as investors grow nervous that the spending itself is excessive. He flagged that this quarter's earnings reports largely failed to meet the market's bar, adding that he hadn't seen investor reactions quite like this before. It's worth noting this was a single trader's client communication, not an official published Goldman Sachs research report, so it carries a different weight than a formal house view. Still, the figure spread quickly across financial media and social platforms, largely because it put a hard number on something many investors were already feeling in their own portfolios: a gap between "the index looks fine" and "my holdings feel terrible."

The clearest single example of that gap is Alphabet. On October 29, Google's parent company plunged roughly 12% in regular trading after its third-quarter earnings, erasing about $500 billion in market value in a single session - not only Alphabet's own worst day on record but the second-largest one-day market-cap loss in U.S. stock market history (this site covered that event in detail in a separate article on October 30). Over the full month of October, Alphabet's cumulative losses reached roughly $758 billion, making it the company's worst month ever. That a single stock could lose that much while the S&P 500 kept hovering near record territory is only possible because of how a market-cap-weighted index works: as long as a handful of mega-cap names hold up, the index's surface can stay calm even while individual components are in freefall. Taken together, the Magnificent Seven (Apple, Microsoft, Amazon, Alphabet, Meta Platforms, Nvidia, and Tesla) have reportedly lost a combined $4 trillion in market value since October 15 - a separate, larger, three-week accumulation distinct from the roughly $1 trillion the same group lost in the single-day midterm-election panic on November 5, which this site also covered separately.

A Calm Index, a Chaotic Market Underneath

The concept that explains this split is market breadth. Index returns and breadth answer two different questions. The index tells you how the aggregate dollar-weighted basket performed today; breadth tells you how many individual names actually went up versus down. In a market where a small handful of mega-caps carry an outsized share of the index's weighting, these two measures can tell completely different stories. When names like Apple, Nvidia, and Microsoft hold steady or dip only modestly, the headline index can keep looking fine, even as hundreds of the index's other constituents - each driven by its own fundamentals, valuation pressure, and the unwinding of AI-driven expectations - quietly grind lower at very different paces.

The danger in this structure is that watching the index alone can give investors a false sense of security. Throughout 2026, semiconductor, cloud, and data-center names riding the AI theme have been punished hard at the first sign of decelerating growth expectations. This site has already covered several concrete pieces of this same pattern: Arm Holdings' royalty-growth miss, Qualcomm's steep handset-revenue decline, and the Nasdaq 100's return to correction territory as AMD, Intel, and Qualcomm all fell double digits within days. Each of those stories made headlines on its own. What Molavi's framing adds is the observation that these aren't scattered, unrelated incidents - they're data points in one broader structural pattern spreading beneath the surface of the index.

A few caveats are worth keeping in mind before taking the 60% figure at face value. First, the exact share of stocks counted as "in a bear market" is sensitive to which 52-week high is used as the reference point, so the number can shift depending on the methodology. Second, this came from an individual trader's client note rather than Goldman's official published research, so it shouldn't be treated as the firm's formal house view. Third, a stock falling into bear-market territory doesn't guarantee further declines - oversold conditions can just as easily attract bargain hunters, which is roughly what happened when beaten-down names bounced following the stronger-than-expected October jobs report on November 6. Even with those caveats, the figure is useful precisely because it quantifies, with a concrete number, just how wide the gap has grown between the calm the index projects and the disorder actually unfolding stock by stock underneath it.

What to Take Away From This

The first lesson is that index-level returns alone don't tell you whether your own portfolio is healthy. "The S&P 500 is near its high, so the market is fine" is a conclusion that can be completely wrong if your holdings aren't concentrated in the handful of names actually propping the index up. Anyone holding individual stocks or sector-specific ETFs should get in the habit of checking that specific holding's own distance from its 52-week high, rather than relying on the headline index as a proxy.

The second lesson is understanding the structural blind spot of cap-weighted indexes. When a small number of mega-caps carry the bulk of an index's weight, the index itself can become a poor proxy for the risk facing the broader market - a state often described as dangerous concentration. During stretches like this, breadth indicators such as equal-weight index performance or the advance-decline line offer a far more honest read on market conditions than the headline index number alone.

The third lesson is learning to weigh the nature of a source appropriately. This "hidden bear market" warning came from Goldman Sachs, a credible institution, but through an individual trader's client note rather than a formal research publication - a distinction that should temper how much weight it carries. At the same time, the fact that this figure lines up consistently with already-confirmed individual events - Alphabet's $500 billion single-day loss, the Magnificent Seven's cumulative $4 trillion drawdown, and the string of double-digit semiconductor selloffs - makes it considerably harder to dismiss as mere exaggeration.

FAQ

How exactly is "bear market" being defined here?

A bear market typically refers to a decline of 20% or more from a prior high. In this case, Molavi's analysis isn't about the S&P 500 index itself falling 20% - the index hasn't come close to that. Instead, it measures what share of the index's individual constituent stocks have each fallen more than 20% from their own 52-week high. The index as a whole remains outside bear-market territory, but a majority of its individual components have already crossed that threshold on their own.

Why hasn't the S&P 500 fallen more if so many of its stocks have?

Because the S&P 500 is calculated on a market-cap-weighted basis, a handful of mega-cap names like Apple, Microsoft, and Nvidia - which each carry an outsized share of the index's total weight - can hold up the headline number even while hundreds of smaller-weighted constituents fall sharply. Those smaller names simply don't move the index enough on their own to show up clearly at the aggregate level.

What should investors watch next?

The nearest checkpoint is Tuesday, November 10, when CoreWeave reports third-quarter earnings on the same day the October Consumer Price Index is released. CPI is expected to come in around 3.9% year-over-year, a reading that could shape expectations for the Fed's December rate decision. Beyond that macro data, the more practical habit for individual investors is checking each of their own holdings' distance from its 52-week high directly, rather than relying on the headline index level to gauge how exposed a portfolio might be to this "stealth bear market" pattern.
