'Stealth' Bear Market Deepens: 60% of S&P 500 Stocks Now Down 20% or More
Key Takeaways
- •More than 60% of S&P 500 companies now trade at least 20% below their record highs, the commonly accepted threshold for bear-market territory.
- •The index's market-cap weighting allows a handful of the largest stocks to hold the headline number near its peak even while most constituents decline.
- •The Magnificent Seven has collectively lost approximately $4 trillion in market capitalization from its highs, an amount that exceeds the entire cryptocurrency market's value.
- •AppLovin leads the declines among large-cap technology stocks with a 68% drop from its all-time high, followed by Coinbase at 62%, CoreWeave at 60%, and Western Digital at 54%.
- •According to The Kobeissi Letter's October 30, 2026 post, the Nasdaq 100 has lost nearly $5 trillion in value since October 6.
The S&P 500 remains remarkably close to its all-time high, but a closer look at the index's internals shows that the damage has worsened considerably over the past several weeks — a widening gap between headline performance and underlying breadth that is often described as a "stealth" bear market.
According to data compiled by financial commentary service The Kobeissi Letter, more than 60% of companies in the benchmark index are now in bear-market territory, while some of the largest technology and crypto-linked stocks have fallen far more sharply.
Near Record Highs, but Broadly in a Bear Market
The analysts reported that over 60% of S&P 500 components now trade at least 20% below their respective record highs, placing them in commonly defined bear-market territory. That gap between the index level and its internals reflects how the S&P 500 is built: because it weights members by market capitalization, a handful of the largest companies can hold the headline number near its peak even while most constituents trade well below theirs. Even some of the biggest names in the market are no longer immune. The analysis shows that four of the Magnificent Seven have dropped 15% or more from their peaks, and the group has collectively erased approximately $4 trillion in market capitalization from its highs — a sum that exceeds the entire cryptocurrency market's capitalization by a wide margin.
The deterioration has accelerated quickly. Alphabet has led the decline, tumbling 31% from its all-time high of $400 to $282. Meta's stock has slumped more than 21% since its mid-August peak and closed last week at around $625.
The adverse developments build on an earlier divergence, when 59% of S&P 500 companies were already at least 20% below their peaks even as a small group of mega-cap stocks continued to support the index. At the time, only ten firms had accounted for roughly 70% of the S&P 500's advance from its March 30 bottom.
Tech and Crypto-Linked Stocks Have It Worst
The Kobeissi Letter's latest list highlights the pressure on technology-related companies. AppLovin has plummeted 68% from its all-time high, followed by a 60% correction in CoreWeave, a 54% drop in Western Digital, and a 51% decline in Oracle. Arm Holdings' shares have nosedived 49%, while Alphabet, Broadcom, Meta, Micron, Adobe, and Intel also feature among the steepest decliners. The roster spans chipmakers, software providers, storage manufacturers, and trading platforms, underscoring how broad the pullback has become across the technology complex.
Crypto-linked equities are among the worst performers as well. The list includes Coinbase, which has tanked 62% from its peak, while Circle is down 48%. Robinhood, which is not exclusively a crypto business but has pushed deeper into the sector over the past year, has dived 44%.

Concentration Support Is Fading
The figures make the current market increasingly difficult to describe as a conventional bull market simply because the headline index remains close to its peak. The concentration that previously kept the S&P 500 near its highs is weakening as losses spread into some of the very companies that had supported the advance. With the index itself still hovering near its record, headline performance alone offers limited visibility into how the typical stock is faring, which is why participation readings of this kind are widely used to gauge underlying market conditions. Future updates to the share of components sitting in bear-market territory will show whether the gap between the index and the average stock narrows or extends.
Nevertheless, The Kobeissi Letter still views the divergence as a potential opportunity rather than necessarily the beginning of a prolonged collapse.
