Stock sector performance
U.S. Sector & Industry Market Performance Report — August 21, 2026
Market Overview
The U.S. market is showing a strong but highly uneven rotation beneath the surface. Broad-market performance remains positive over the medium term, but the latest session reveals significant divergence between defensive/commodity-linked groups and high-beta technology, industrial and consumer segments.
The clearest theme is capital rotating toward resources, healthcare, energy and selected defensive industries, while several previously strong growth areas are experiencing meaningful short-term selling pressure.
Market Breadth Snapshot
| Index | Current | Daily Move | 1W | 1M | 3M | 6M |
|---|---|---|---|---|---|---|
| U.S. Market | 1,858.76 | +18.59 | +2.76% | +3.19% | +19.39% | +11.88% |
| Large Cap | 1,719.78 | +2.51% | +1.85% | +19.59% | +10.40% | |
| Mid Cap | 2,381.72 | +3.10% | +7.55% | +16.73% | +15.10% | |
| Small Cap | 2,098.12 | +4.02% | +5.50% | +23.01% | +17.30% | |
| Low Cap | 2,276.45 | +3.42% | +6.82% | +18.86% | +15.88% | |
| Top Cap | 1,870.94 | +2.63% | +2.95% | +19.00% | +11.31% |
Key Takeaway
Small- and mid-cap stocks continue to outperform large caps.
That is an important market signal. The stronger performance in smaller companies suggests that the rally is not solely dependent on mega-cap technology.
At the same time, the latest short-term sector moves indicate that the character of the rally is changing.
Sector Leadership
1. Healthcare — Major Relative Strength
U.S. Health Care Index
- Current: 1,829.78

- Daily: +2.08%
- 1W: +8.40%
- 1M: +4.21%
- 3M: +25.88%
- 6M: +21.28%
Materials are benefiting from a broad commodities-driven move.
Even more impressive is the performance of Basic Resources:
- Daily: +3.43%
- 1W: +23.85%
- 1M: +11.89%
- 3M: +68.05%
- 6M: +28.93%
This is a major momentum pocket.

- 3M: +58.41%
- 6M: +55.23%
Energy is exhibiting one of the strongest multi-timeframe trends in the market.
The leadership is particularly broad because producers, exploration companies, integrated energy and oilfield services are all showing strong momentum.
Gold & Mining — Extreme Momentum
One of the most striking areas of the entire dataset is mining.
Gold Mining
U.S. Gold Mining Index
- Daily: +13.85%
- 1W: +44.58%
- 1M: +19.44%
- 3M: +87.06%

This is extraordinary momentum.
Mining
U.S. Mining Index
- Daily: +13.25%
- 1W: +43.57%
- 1M: +18.49%
- 3M: +80.34%
- 6M: +27.06%
The magnitude of the move suggests that the market is aggressively repricing the resource complex.
Nonferrous Metals
- Daily: +6.57%
- 1W: +21.14%
- 1M: +17.00%
- 3M: +72.40%
- 6M: +40.22%
This reinforces the idea that the commodity/resource trade has become a major market leadership theme.

- 1W: +9.64%
- 1M: +19.33%
- 3M: +54.00%
- 6M: +21.57%
Healthcare is no longer simply a defensive trade.
The strength in biotechnology and pharmaceuticals indicates substantial participation from higher-beta healthcare industries.
Technology — Strong Long-Term Trend, Weak Short-Term Breadth
Technology remains one of the strongest long-term areas, but the latest trading session shows substantial profit-taking.
Technology
U.S. Technology Index
- Daily: -3.57%
- 1W: +2.59%
- 1M: +0.55%
- 3M: +31.69%
- 6M: +17.35%
Semiconductors
U.S. Semiconductors Index
- Daily: -5.22%
- 1W: +2.33%
- 1M: -2.22%
- 3M: +57.30%
- 6M: +36.88%
Technology Hardware
- Daily: -3.47%
- 1W: +1.02%
- 1M: +0.20%
- 3M: +56.04%
- 6M: +33.88%
Software
- Daily: -3.80%
- 1W: +15.99%
- 1M: +11.95%
- 3M: -6.28%
- 6M: -2.62%
The message is clear:
Technology’s long-term trend remains strong, but short-term momentum has become considerably more fragile.
Semiconductors are particularly interesting because the sector remains massively higher over three and six months despite the sharp daily decline.
Electronics — Significant Selling Pressure
The weakest technology-adjacent areas include:
Electrical Components & Equipment
- Daily: -8.06%
- 1W: -3.75%
- 1M: -3.84%
- 3M: +38.59%
- 6M: +29.88%
Electronic Equipment
- Daily: -7.40%
- 1W: +1.55%
- 1M: +0.53%
- 3M: +65.11%
- 6M: +35.57%
This looks more like profit-taking within powerful longer-term trends than a confirmed structural breakdown.
Industrials — Broad Weakness
Industrial stocks are experiencing meaningful short-term pressure.
U.S. Industrials
- Daily: -3.87%
- 1W: +1.15%
- 1M: +3.98%
- 3M: +18.48%
- 6M: +14.69%
Aerospace & Defense
- Daily: -4.54%
- 1W: +2.71%
- 1M: +5.53%
- 3M: +17.72%
- 6M: +8.49%
Industrial Engineering
- Daily: -3.20%
- 1W: +0.31%
- 1M: +3.16%
- 3M: +35.17%
- 6M: +21.15%
Industrial Metals & Mining
- Daily: -4.18%
- 1W: +10.03%
- 1M: +6.37%
- 3M: +62.13%
- 6M: +31.57%
Industrials remain structurally strong but are clearly undergoing short-term rotation and profit-taking.
Financials — Mixed Picture
Financials are not participating as aggressively as resources and healthcare.
Financials
- Daily: -2.08%
- 1W: +0.99%
- 1M: +8.59%
- 3M: +8.37%
- 6M: +4.57%
Banks
- Daily: -4.21%
- 1W: +0.77%
- 1M: +13.26%
- 3M: +21.68%
- 6M: +8.11%
The banking group remains healthy on a medium-term basis, but today’s decline shows renewed selling pressure in financials.
Consumer Sector — Increasingly Uneven
Consumer-related groups are showing some of the clearest signs of weakness.
Retail
- Daily: -2.54%
- 1W: +2.47%
- 1M: -3.51%
- 3M: +1.14%
- 6M: +4.39%
Automobiles
- Daily: +1.33%
- 1W: -5.13%
- 1M: -14.40%
- 3M: +9.29%
- 6M: -20.61%
Airlines
- Daily: -11.23%
- 1W: -7.10%
- 1M: +5.78%
- 3M: +12.58%
- 6M: -0.53%
Footwear
- Daily: -3.35%
- 1W: -9.07%
- 1M: -7.06%
- 3M: -39.04%
- 6M: -29.68%
Consumer cyclicals are clearly lagging the resource and healthcare leadership.
Real Estate — Stabilizing, But Still Selective
The broad real-estate picture is mixed.
Real Estate
- Daily: -0.08%
- 1W: -0.59%
- 1M: +1.80%
- 3M: +7.94%
- 6M: +10.76%
REITs are similarly stable:
- Daily: -0.10%
- 1W: -1.21%
- 1M: +1.21%
- 3M: +11.26%
- 6M: +13.55%
The group isn’t leading the market, but the medium-term trend remains constructive.
Telecommunications — Relative Resilience
Telecommunications are behaving better than technology and industrials during the latest rotation.
Telecommunications
- Daily: +1.53%
- 1W: +9.23%
- 1M: +0.68%
- 3M: -8.93%
- 6M: +6.36%
Fixed-line telecommunications are particularly strong over the short term:
- Daily: +2.32%
- 1W: +14.58%
This represents a meaningful short-term defensive rotation.
Utilities — Defensive but Lagging
Utilities remain comparatively subdued.
Utilities
- Daily: -0.89%
- 1W: -2.89%
- 1M: -2.00%
- 3M: +0.86%
- 6M: +1.73%
This is not a strong leadership group. Capital is instead moving toward healthcare, energy, mining and selected defensive communication areas.

What the Market Is Saying
The most important message from this dataset is that this is not simply a risk-off market.
If investors were broadly abandoning risk, we would expect defensive sectors to dominate while commodities, small caps and biotechnology weakened.
Instead, we’re seeing something different:
Capital is rotating.
Money is moving toward:
Resources + Energy + Healthcare + Small/Mid Caps
while taking profits from:
Technology + Industrials + Consumer Cyclicals + selected financials.
That creates a market environment where the headline index can remain healthy while individual sectors experience very large internal rotations.
Technical Market Read
Bullish Signals
- Small caps significantly outperforming large caps.
- Mid caps showing strong relative strength.
- Energy producing powerful multi-month gains.
- Mining and gold exhibiting exceptional momentum.
- Healthcare accelerating across multiple timeframes.
- Biotechnology confirming healthcare strength.
- Basic resources maintaining strong breadth.
- Semiconductor and technology trends remain substantially positive over three months.
Warning Signals
- Technology is experiencing substantial daily selling.
- Semiconductor momentum has weakened over the one-month timeframe.
- Industrial stocks are under pressure.
- Financials are pulling back.
- Consumer cyclicals remain weak.
- Airlines are experiencing severe selling.
- Several previously high-performing industries are showing large one-day declines.
Bottom Line
The U.S. equity market remains structurally bullish, but leadership is undergoing a major rotation.
The strongest evidence is coming from energy, mining, gold, materials, healthcare and smaller-cap stocks.
Technology remains a major long-term leadership group, but its recent weakness suggests that investors should not assume that every part of the growth trade will continue moving higher at the same pace.
The most important trend to watch now is whether the current rotation becomes a healthy broadening of the bull market or develops into a more aggressive de-risking event.
For now, the data favors the first interpretation.
