Price returns from NSE closing prices, adjusted for splits and bonuses, excluding dividends. "1 month" and "From 52-wk high" are as of 27 October 2026.

How these numbers are made

  • Chain-linked, adjusted for splits and bonuses.Each session’s move is NSE’s closing price divided by the previous close. NSE’s bhavcopy does not restate that previous close when a share splits or issues bonus shares, so on each ex-date it is adjusted with the ratio from NSE’s own corporate-action list: a 1:1 bonus halves it, and never shows as a 50% fall. Rights issues are adjusted to the theoretical ex-rights price. Multiplying the daily moves over a period gives its return.
  • Price return.Dividends are not added back. On a demerger or capital reduction the day’s move runs from the price NSE discovers in that morning’s special pre-open session, and shares received in a demerged company are not counted.
  • Closing basis. Every figure uses closing prices. The 52-week high and low are the highest and lowest closes of the last 52 weeks, restated for splits and bonuses, not the intraday extremes an exchange quotes.
  • Which stocks.Nifty 50 and Nifty 500 are today’s index members, so a stock that left an index during the period is not in its list. “All liquid stocks” are companies in NSE’s list of equities (so no ETFs), trading in the EQ series, that closed at Rs 10 or more, averaged at least Rs 1 crore of turnover a session over the period and traded on at least 80% of its sessions, which keeps penny and thinly traded shares off the lists.
  • New listings and gaps.A company that listed during the period is measured from the close of its first trading day, not its IPO price, and marked “Listed”. A stock whose record starts inside the period for another reason, such as a change of NSE symbol (treated as a new series under the new symbol), a return from suspension or a first day on NSE after listing only on BSE, is measured the same way and marked “From” that date. A stock that did not trade on a session simply has no move that day; rows in NSE’s trade-for-trade series (BE, BZ) stay in its chain.
  • Source.NSE’s daily bhavcopy (latest file), its corporate-action list (daily PR file), NSE’s Nifty 50 and Nifty 500 member lists, and its list of equities for names and listing dates. Updated after every NSE close, usually by 7.30 pm.

How many Nifty 500 stocks are down this week?

119 of the 497 Nifty 500 stocks are lower this week, 378 are higher. The median Nifty 500 stock is up 2.0% over 2 sessions.

How are the returns this week calculated?

Each day's move is the closing price divided by the previous close, from NSE's daily bhavcopy. NSE does not restate that previous close when a share splits or issues bonus shares, so on each ex-date it is adjusted using NSE's own corporate-action list: halved for a 1:1 bonus, cut to a fifth for a split from Rs 10 to Rs 2. Multiplying the daily moves over the period gives the return. Prices are closing prices; dividends are not added back, so these are price returns. This period runs from the close on 23 October 2026 to the close on 27 October 2026.

Do these returns include dividends?

No. These are price returns. Dividends paid during the period are not added back, so a high-dividend stock's total return to a shareholder is higher than shown. Splits, bonus issues and rights issues are adjusted for, using NSE's corporate-action list.

Which stocks are counted?

The Nifty 50 and Nifty 500 are today's index members as NSE lists them. "All liquid stocks" means companies in NSE's list of equities (no ETFs), trading in the EQ series, that closed at Rs 10 or more, averaged at least Rs 1 crore of turnover a day over the period and traded on at least 80% of its sessions.
