How is the score calculated?
Find the share of eligible stocks above their 20-session moving average in each sector, then add the 11 sector percentages to get the Breadth Score. Every sector has equal weight. Divide the score by 11 to get Breadth Percent, also called Sector Balanced Breadth.
Calculation coverage · 501 of 503 constituents eligible · 99.60%
Each sector uses the constituents included in that calculation as its denominator. Stocks may be excluded because of trading-history rules or unavailable price inputs. The full constituent universe and calculation coverage are retained.
Every included stock requires the full 20-session price window and must be strictly above its SMA20 to count as above. Each exclusion records its reason for that session.
