AGENT BRIEF
Read the underlying story.
Narrow participation
The index is up. Most constituents are not.
- 01
The sample index moves +0.85%, while 37 of 100 constituents advance and 63 decline.
- 02
The ten largest weights contribute +0.97 percentage points. The other 90 contribute -0.12 percentage points.
- 03
5 of 6 sectors have a positive weighted return. The headline gain masks weak participation across individual constituents.

A fictional universe, visible assumptions.
The UKOOM Sample 100 contains 100 invented companies, SIM001–SIM100. The first ten each carry 4.5% weight; each of the other 90 carries 55/90%. The same weights are used in all three scenarios. Moves are illustrative changes over one simulated period.
The first ten are allocated to Technology (4), Communication (2), Financials (2), Industrials (1), and Consumer (1). The remaining constituents cycle evenly through the six sectors.
Reproducible calculations.
Index move: sum of weight × constituent change, with weights expressed as fractions. Contribution: the same sum for the selected group, in percentage points. Breadth: advancing constituents ÷ all constituents. Sector return: sector contribution ÷ sector weight.
