The Power Index ranks the 11 S&P 500 sectors by relative performance for the short window ending March 17, 2026 (Monday close → Tuesday close), using close-to-close percentage change in USD. Sector proxies are XLY for Consumer Discretionary, XLK for Technology, XLF for Financials, XLE for Energy, XLRE for Real Estate, XLI for Industrials, XLB for Materials, XLC for Communication Services, XLU for Utilities, XLP for Consumer Staples, and XLV for Health Care.
The table did not line up with the simplest version of the macro story. Oil stayed elevated, but energy did not take first. Consumer Discretionary led the ranking, Technology followed, and Financials held third. Health Care finished last, while Staples and Utilities also sat near the bottom. This was not a defensive table. It was a selective participation table.
Ranked: The Mismatch
Consumer Discretionary taking first is the detail that changes the feel of the whole ranking. If the market were only reacting to oil pressure, inflation sensitivity, and headline caution, Discretionary would not be sitting at the top. Money paid for it anyway. That does not mean the market turned carefree. It means leadership inside equities was broader and less defensive than the cross-asset backdrop would suggest.
Technology in second keeps another familiar pattern alive. Large-cap growth still matters. It did not dominate the table outright, but it stayed close enough to the top to show that money still wants exposure to the part of the market with the most consistent participation. This is now less about one dramatic surge and more about persistence. Tech keeps showing up near the front of the line.
Financials in third and Energy in fourth are where the structure becomes more interesting. Energy staying high is not a surprise. But failing to take first is. In a window where oil remained loud, the sector that normally carries that message most directly was outranked by consumer and technology exposure. Financials holding above energy also adds to that mismatch. Money was not hiding from cyclicality. It was choosing among cyclicals.
Then there is the bottom of the table. Health Care finished last, with Staples and Utilities also in the lower tier. That is the opposite of what a textbook defensive shuffle would look like. It suggests that inside equities, the market was not paying up for the classic stabilizers. It was paying for participation, but only in selected places.
That is the key tension in the ranking. Cross-asset leadership still points toward hard assets and an inflation-sensitive backdrop. Inside equities, the sector order looks more willing to lean into consumer activity, technology strength, and financial participation than the broader macro story would imply. The market did not become simple. It became layered. And layered tables are usually where the more durable signals start to hide.
