Breadth / Concentration

Concentration risk gets dangerous when leadership stops broadening.

Both metrics on this page are explicit proxies, not constituent-perfect measurements, and the UI says so on purpose.

Not enough historical data to render a chart yet.

Thresholds

healthyLeadership breadth is broad.0 pts
narrowingLeadership is narrowing somewhat.5 pts
concentratedBreadth is deteriorating materially.10 pts
extreme_concentrationLeadership is extremely narrow.15 pts

Methodology

Compares six-month returns of RSP and SPY as a breadth proxy.

((RSP_t / RSP_t_minus_6m) - 1 - ((SPY_t / SPY_t_minus_6m) - 1)) * 100

This is a proxy and is not the same as full constituent breadth.

ETF structure and sector exposures can influence the spread.

Methodology

Uses a curated proxy series for top-10 concentration.

top10_concentration_proxy = curated_top10_share_percent

This is explicitly a proxy and not an official constituent-perfect measure.

The current implementation depends on a curated local source for reproducibility.
