Why is the S&P 500 near its high while my stocks are down?
Because an index’s high is the high of the whole basket, not of each stock in it. Two things combine to hide a lot of individual damage.
Weighting. The S&P 500 weights companies by market value, so a few giants move it most. On Oct 23 several of them were at or near their highs: Apple was 0.1% below, Berkshire Hathaway 0.9%, Eli Lilly 2.5% and Microsoft 3.5%. How much this concentration matters over time is in equal‑weight vs cap‑weight S&P 500.
Dispersion. Weighting is only part of it. The equal‑weight S&P 500 ETF (RSP), which gives each company about the same slice, was 2.43% below its high, almost the same as SPY at 2.45%. So the average stock, held as a basket, was near a high too. The gap comes from how far apart the members are. Some stocks were at or near new highs while others were 30%, 50% or more below theirs, and different stocks peaked at different times over the past year. Gains in one group offset losses in another, so the basket stayed close to its high while a third of its parts sat in their own bear markets.
For a portfolio of individual stocks, this means the index is a poor guide to how your holdings feel. If they lean toward the sectors below, a 2.5% dip in the index can sit beside 20% to 40% losses in single names.
Are the biggest S&P 500 stocks in a bear market?
Some are. Of the 20 largest members, six were 20% or more below their 52‑week highs on Oct 23: Intel, Broadcom, Micron, Tesla, Alphabet and AMD. Nvidia was 11.8% below its high. Apple, Berkshire Hathaway, Exxon Mobil, AbbVie, Visa and Mastercard sat at or within 2% of theirs.
| Company | From 52-week high | Company | From 52-week high |
|---|
| Nvidia | −11.8% | Micron | −27.7% |
| Apple | −0.1% | Walmart | −10.4% |
| Alphabet | −20.4% | AMD | −20.4% |
| Microsoft | −3.5% | JPMorgan Chase | −8.7% |
| Amazon | −12.7% | Visa | −1.5% |
| Meta Platforms | −17.4% | Exxon Mobil | 0.0% |
| Broadcom | −33.0% | Johnson & Johnson | −5.3% |
| Tesla | −24.0% | Mastercard | −1.5% |
| Eli Lilly | −2.5% | AbbVie | −1.2% |
| Berkshire Hathaway | −0.9% | Intel | −38.3% |
The deepest falls were further down the list. AppLovin was 64.5% below its 52‑week high, Fiserv 60.6%, Insulet 57.0%, CoStar Group 56.6%, Boston Scientific 56.5%, Charter Communications 56.4%, Albemarle 56.3%, Fair Isaac 55.8%, Oracle 54.9% and Coinbase 54.5%. A deep fall says what already happened. It does not say whether a stock is cheap or will recover; big long‑term winners also went through falls like these, as the drawdowns of big winners shows.

Has this happened before?
Rarely. Among month‑ends since 2017 when the index was within 3% of its high, only September 2026 (37.6%) and July 2020 (34.0%) were higher than Oct 23. Across 115 month‑ends from March 2017 to September 2026, plus Oct 23, 2026, the median share of members in their own bear market was about 20%. The share runs high in real index sell‑offs: 79.6% in March 2020 and 71.0% in September 2022. It drops to a few percent in calm, broad rallies, such as 2.9% in June 2021.
| Month-end | Share of members 20%+ below high | SPY below its 52-week high |
|---|
| Dec 2017 | 4.9% | −0.5% |
| Dec 2018 | 49.7% | −14.0% |
| Dec 2019 | 7.0% | −0.3% |
| Mar 2020 | 79.6% | −23.4% |
| Dec 2020 | 14.0% | 0.0% |
| Jun 2021 | 2.9% | 0.0% |
| Dec 2021 | 10.8% | −0.5% |
| Jun 2022 | 68.7% | −20.4% |
| Sep 2022 | 71.0% | −24.4% |
| Dec 2022 | 46.7% | −18.6% |
| Oct 2023 | 37.0% | −8.3% |
| Dec 2023 | 10.7% | −0.3% |
| Dec 2024 | 22.4% | −3.3% |
| Apr 2025 | 44.0% | −9.3% |
| Dec 2025 | 23.7% | −1.2% |
| Mar 2026 | 35.6% | −6.2% |
| Jun 2026 | 31.9% | −1.4% |
| Sep 2026 | 37.6% | −1.7% |
| Oct 23, 2026 | 32.0% | −2.5% |
The unusual part of 2026 is the gap between the two columns. In past sell‑offs a high share of fallen stocks came with a falling index. At the month‑ends from March to September 2026, and on Oct 23, the share was between 28% and 38%, while SPY was within 2% of its high at eight of the nine month‑ends of 2026. Among the 68 month‑ends (plus Oct 23) when SPY was within 3% of its high, these had the highest shares:
| Month-end with SPY within 3% of high | Share 20%+ below high | SPY below high |
|---|
| Sep 2026 | 37.6% | −1.7% |
| Jul 2020 | 34.0% | −2.5% |
| Oct 23, 2026 | 32.0% | −2.5% |
| Jun 2026 | 31.9% | −1.4% |
| May 2023 | 31.2% | −1.5% |
| Aug 2020 | 31.1% | −0.4% |
In 2026 the equal‑weight basket is near its high as well, which points to wide gaps between groups of stocks rather than to a handful of giants alone. A different lens, how many stocks beat the index over the past year, is in is the stock market rally too narrow. How investors read the wider backdrop, and why the 20% rule describes the past, is in are we in a bull or bear market.
