The market at the last close, against its own history

Every stock, against its own past

Each dot is one of the 500 most traded NSE stocks, placed by its stretch score: how its price compares with its own last five years, from washed out on the left to stretched on the right. Rows are sectors. No stock is named here; in the extension, your own stocks are marked and named.

Sectors over time

The share of each sector’s stocks that were stretched (a score of 70 or more), at the end of each week or each month. Darker means more of the sector was stretched against its own history. The arrows show which sectors heated up or cooled off over the last four weeks.

Every trading day since 2018

One square per trading day, shaded by how much of the market was stretched that day. Deep amber runs mark broad run-ups, when much of the market was stretched; the palest runs mark sell-offs and quiet markets.

Stretched stocks

The share of the 500 most traded NSE stocks whose stretch score is 70 or more: high against their own last five years. This is the same figure as the market weather in the extension.

Unusually bad days

The share of stocks whose fall that day was worse than 95% of their own days over the previous year. Each stock is judged against its own history, so a 3% fall counts for a steady stock but not for a volatile one. On a typical day about 5% of stocks qualify by chance; much more than that means weakness was unusually widespread.

How unusual the day was

How far the day’s returns across sectors were from their usual pattern over the previous two years, taking into account how sectors normally move together (a Mahalanobis distance, on equal-weighted sector baskets). Shown as a percentile: 90 means the day was more unusual than 90% of days since 2018. Unusual days happen in rallies as well as falls.

Good to know

• Measured on today’s 500 most traded NSE stocks, including for past days, so the history leaves out companies that have since fallen out of that group.
• Updated each trading evening after the exchanges publish their files.
• In our testing, how stretched the whole market was did not help predict how an individual stretched stock behaved. These figures are context for reading the news, not a signal. The Track record has the tests.
