Sector Attention Breadth · weekly · issue 2026-09-14 · data as of 2026-09-11
Which sectors are gaining web attention broadly, and which gains rest on a few names?

Communication Services posts the highest share of advancing names at 66.7% across 76 advancing names, while Basic Materials posts the lowest share of advancing names at 45.0%. Healthcare holds the highest net-breadth index at 4.13, whereas Technology holds the lowest net-breadth index at 0.68.

Communication Services records the highest gain share metric at 50.7%, supported by DISCA, LBTYK, and HUYA. Financial Services records the lowest gain share metric at 21.4%.

Technology recorded 208 advancing names, and Industrials recorded 156 advancing names in web attention.

Breadth describes participation, not value and not a return forecast. · Sector is each name's current label applied to its whole history.

Advancers = names whose attention value rose day over day; the Names column is the count with a prior session. The index sums daily (advancers − decliners) ÷ (advancers + decliners) over the window, rebased to zero at the start. Top-5 share of gains = the share of the sector's summed positive day-over-day log change in attention value over the last 7 calendar days (about five sessions) carried by its five largest contributors, equal-weighted per name with share classes of one company counted once; 100% means five or fewer names carried the whole advance, and a blank means no name in the sector advanced. Breadth describes participation, not direction of value. Groups under 20 names, the unclassified residual and the crypto bucket (an asset class, not a sector) are excluded from this table and from the headline; they remain in the sector-sigma ridge only if it draws them. Sector is each name's current label applied to its whole history. As of: 2026-09-11 (all rows).

We read this as two different things sharing one label. Communication Services' chart-topping participation rests on a handful of names and will not hold. Its 66.7% advancing share sits alongside a 50.7% top-five share of gains and a -16.2% step down in participation. By contrast Technology (62.8% advancing, 21.6% top-five) and Financial Services (61.1%, 21.4%) show participation spread across far larger universes, and Utilities at 48.1% top-five looks as thin. Communication Services' advancing share prints below 60% in the next issue.

What would show this wrong: Communication Services shows an advancing share of 60% or higher in the next issue's breadth table.

Attention gains across Financial Services reflect broad-based crowd participation rather than isolated single-stock spikes. The sector combines an advancing share of 61.1% with the universe's lowest top-five gain concentration at 21.4%, contrasting with Communication Services where top names drive 50.7% of gains. With 181 advancing names, crowd attention is diffusing evenly across banking and financial constituents. Financial Services will record a Top-5 share of gains of at most 28.1% in the next issue.

What would show this wrong: Financial Services records a Top-5 share of gains greater than 28.1% in the next issue.

Communication Services' attention lead rests on a handful of media names rather than sector-wide participation. It posts the top advancing share at 66.7%, yet its Top-5 share of gains is 50.7%, carried by DISCA, LBTYK and HUYA, the most concentrated of any sector. By contrast the lowest gain-share readings, Financial Services at 21.4% and Technology at 21.6%, show gains spread across many names. We read the crowd as clustering on a few media stories rather than re-engaging with the sector as a whole. Communication Services' Top-5 share of gains will remain above 40% in the next issue.

Known open data defects affecting this publication: Digital-asset market caps are present but stale: the upstream cap feed froze silently. (2026-02-17 to 2026-08-04); A name whose attention falls below the publication floor silently leaves the published universe; the exit is indistinguishable from a delist (always); The historical cross-section is today's universe backfilled: a name onboarded later carries rows for earlier dates. 115 of 2,135 names end b (2015-05 to 2026-08); A two- or three-letter US ticker collides with a foreign listing code, so the name's source-page set includes another company's pages and it (whole history). Coverage & data quality

Method

Attention breadth counts participation: on each session, how many names in a sector saw their attention value rise versus fall against the previous session, summed over a 90-day window into a net-breadth index per sector. It is computed on attention levels, never on the within-day value gap (a gap-based advance/decline splits half and half by construction). The ridge shows, for the eight largest sectors, the distribution of every name's attention sigma against its own trailing year, with the tails named, so a sector-level move can be read as broad or as a handful of outliers. Its per-sector n is not the breadth table's n: the ridge counts names with a full trailing year of sigma, while the breadth table counts names with a reading in the latest session across every group, so the two count different populations and neither is a subset of the other. Groups under 20 names, the unclassified residual and the crypto bucket (an asset class, not a sector) are excluded from the breadth table and from the headline; they remain in the sector-sigma ridge only if it draws them. The two crossover tables list the week's names moving above or below their own 50-day attention trend.

Breadth describes who is participating in attention gains. It is not a valuation, a timing signal, or a return forecast; regime-return claims on attention breadth failed placebo tests in our own research and are not made here.

The Top-5 share of gains column answers the question's second half directly: for each sector, the share of the week's summed positive day-over-day log change in attention value that its five largest contributors carried, equal-weighted per name so a mega-cap's move counts the same as a small cap's equal percentage move, with share classes of one company counted once. A high share means the advance rests on a few names; a low share means it was broad. Sector is each name's current label applied to its whole history, so a name reclassified later is counted under its new sector throughout.
