Index level
BSE Sensex closed at 73,607 on October 26, 2026, up 0.66% on the previous session.
ATLAS breadth
29 of 29 members (100%) have a probability above 50% of closing higher in a month in ATLAS's model.
Of 28 members with a fair value estimate, 6 trade at least 8% below it and 19 at least 8% above; the median gap is +28%.
How to read it: ATLAS's calibrated model uses the same long-run drift for every stock, so the share above 50% mostly reflects how many members are calm enough (low volatility) to sit above a coin flip. It gauges how calm the index is, not where it is going.

How this page is built
Members: the list of companies in the BSE Sensex comes from an index-data provider and is refreshed every week. Companies ATLAS does not publish (too small, no data or not listed in the country) are left out, so this page covers 29 of 29.
Price, fair value and probability come from the same stored data as each company page; probabilities use ATLAS's calibrated one-month model. The index level and daily change are for the last close of the index.
Limits: this is not the official index factsheet. Weights are estimated from market value, probabilities are not forecasts, and nothing here is investment advice.
