NEW YORK, August 20, 2026, 13:21 EDT
- The S&P 500 declined 0.4% after the 10-year Treasury yield touched 4.700%.
- A forward multiple of 20.0 times suggests an earnings-yield cushion of just 30 basis points.
- Energy advanced, but declines in megacap technology and consumer stocks weighed on the index.
The S&P 500 (INDEXSP:.INX) dropped 0.4% on Thursday alongside an increase in long-term Treasury yields. The shift is significant since the index’s forward earnings yield now only slightly exceeds the 10-year note.
With forward earnings at 20.0 times, the implied yield stands at 5.00%. That compares to a 4.700% Treasury yield, putting the initial spread at just 0.30 percentage point. The figures are based on FactSet’s August 7 valuation snapshot and Thursday’s market yield.
| Market snapshot | Level / move | Verified time |
|---|---|---|
| S&P 500 | 7,673.75; -0.44% | 12:15 EDT |
| Nasdaq Composite | 26,087.53; -0.92% | 12:15 EDT |
| 10-year Treasury | 4.700% | 12:15 EDT |
| 30-year Treasury | 5.244% | 12:15 EDT |
| S&P energy sector | up 1.4% | 12:15 EDT |
| S&P consumer staples | down 1.5% | 12:15 EDT |
According to current valuation measures, the gap remains narrow. This allows less tolerance for disappointing earnings or further increases in yields. While investors continue to gain from equity growth, they are exposed to substantially higher volatility compared to those holding Treasuries.
| Valuation scenario | Forward P/E | Indicated earnings yield | Spread above 4.700% Treasury |
|---|---|---|---|
| August 7, 2026 | 20.0× | 5.00% | 30 bp |
| Five-year average | 19.9× | 5.03% | 33 bp |
| Ten-year average | 19.0× | 5.26% | 56 bp |
Rising profits are driving results. FactSet has estimated third-quarter earnings will climb 27.4%, with fourth-quarter growth at 25.2%. According to Citadel Securities, the forward multiple was about 20.1 times as of August 10, compared with 23.1 last October.
On Thursday, that valuation came under scrutiny. Shares of Walmart Inc. NASDAQ:WMT slid 9.2% following a quarterly profit that fell short of forecasts. According to Emarketer analyst Sky Canaves, its modestly improved outlook may not be enough to renew investor confidence.
Consumer discretionary stocks weighed heaviest on the index. Shares of Amazon.com Inc. NASDAQ:AMZN and Tesla Inc. NASDAQ:TSLA declined as well. The energy sector advanced, supported by a 2.1% climb in oil, leading to a pronounced divergence within the market.
| Selected constituent | Index weight | Share move | Simple index effect |
|---|---|---|---|
| Walmart | 1.19% | -8.77% | -0.10 pp |
| Amazon | 4.06% | -1.49% | -0.06 pp |
| Alphabet classes | 5.98% | -0.84% weighted | -0.05 pp |
| Microsoft | 5.14% | -0.49% | -0.03 pp |
| Nvidia | 7.54% | -0.31% | -0.02 pp |
| Apple | 6.65% | +0.15% | +0.01 pp |
Nvidia Corporation NASDAQ:NVDA, Apple Inc. NASDAQ:AAPL, Microsoft Corporation NASDAQ:MSFT and Alphabet Inc. NASDAQ:GOOGL continue to carry enough weight to influence daily index performance. However, Wall Street generally maintains high ratings on these companies. This dynamic leaves the index tied closely to expectations for future earnings.
| Company | Consensus | Analysts | Average target |
|---|---|---|---|
| Nvidia | Strong Buy | 61 | $304.64 |
| Microsoft | Strong Buy | 56 | $569.56 |
| Apple | Buy | 45 | $326.34 |
| Amazon | Strong Buy | 60 | $326.84 |
| Alphabet | Strong Buy | 64 | $428.07 |
Bond supply added to the strain. A soft 30-year Treasury auction came after earlier auctions this week also saw tepid demand. Lawrence Gillum at LPL Financial described Washington’s planned buybacks as “more of a band-aid than a panacea.” Reuters
The index also showed negative breadth. On the New York Stock Exchange, decliners led advancers by a ratio of 1.65 to one. The S&P posted 16 new 52-week highs, while there were only two new lows.
The instant assessment for investors is simple. Should yields remain around 4.7%, earnings forecasts are expected to support valuations. Otherwise, an adjustment to a lower multiple would be required.
Risks: The 30-basis-point number is a sample illustration, not a prediction. Treasury yields, projected profits and index values are in constant flux. The earnings yield does not take dividends, share repurchases or long-term growth into account.

Earnings growth must deliver
FactSet forecasts. The multiple has already compressed from roughly 23.1× last October, so profits—not re-rating—now carry the bull case.
