The Power Index ranks the 11 S&P 500 sectors by relative performance for the week ending April 10, 2026, using the Monday close to Friday close window. This is the Monday slot, so the read is built from the completed weekly sector structure already in hand after Friday’s close.
The top of the table changed a lot. The bottom did not. Technology moved up to first after sitting fourth in the prior sector post. Energy stayed last again. Most sectors finished the week higher, but the gains still leaned toward a small group near the top. This was not broad leadership. It was a selective lift.
Ranked: The Narrow Lift
Technology finished first at about +4.27% for the week. Industrials sat right behind it at about +4.20%. Consumer Discretionary took third at about +3.53%.
That is the real top tier.
Not vague strength.
Not a soft label.
A three-sector block, all up more than 3.5% in the same weekly window.
Now tighten the read.
The top 3 sectors drove about half of all positive sector gains this week. Add Materials and the top 4 drove about 64%.
That changes the read.
Yes, most sectors moved up.
But the move still centered in a small part of the board.
That is the key distinction.
The table improved.
Participation did not fully open.
Now look at the bottom.
Energy finished last at about -2.18%. Consumer Staples was the only other sector in the red, at about -0.35%.
That lower tier is clean.
This was not a week where the market sold everything.
It sold energy.
That matters.
Last place here is not just weak.
It is an isolated weakness.
Now look at the middle.
Real Estate, Communication Services, and Financials sat in the middle of the board. They held gains, but they did not push into leadership. Utilities and Health Care stayed lower, but they did not fully crack.
Money held them. It did not chase them.
That is not a fresh rotation.
That is partial participation.
One more reference keeps the read clean.
SPY rose about +3.12% for the week. RSP rose about +1.41%.
That is a gap of about 1.71 points.
That gap shows the average stock still lagged the index.
So the market did move up.
But the move still leaned on stronger names more than the full board.
And that is the real structural read from this table:
Money did not rush into all 11 sectors.
It was crowded into a short list.
Technology took control.
Industrials and Consumer Discretionary followed.
Energy stayed cut off at the bottom.
The market rose. But it did not rise evenly.
That leaves one tension still sitting inside the table:
The top of the board changed.
But the market still did not fully open up.
