Stock Splits in India: Face Value Explained

A stock split in India is announced as a change in face value, ₹10 to ₹2 or ₹10 to ₹1, rather than as the 5:1 or 10:1 ratio a US filing would quote. The event underneath is the same one: every holder ends up with more shares, each carrying a proportionally smaller price, and the company's paid-up capital does not move. The notation is the only thing that differs, and translating between the two takes one division.

How a stock split in India is announced

Every Indian share carries a face value, also called par value: a nominal rupee amount recorded in the company's books. It is a bookkeeping figure with no link to the market price, and a share with a ₹10 face value can trade at ₹3,400. What the face value fixes is the paid-up capital, which is the face value multiplied by the number of shares issued.

A split cuts the face value and multiplies the share count by the same factor, leaving that product unchanged. A move from ₹10 to ₹2 divides the face value by five and multiplies the share count by five, which is the 5-for-1 split a US company would announce in ratio form. A move from ₹10 to ₹1 is a 10-for-1. A move from ₹2 to ₹1 is an ordinary 2-for-1, and the starting face value is why two announcements carrying the same ratio can read so differently.

The translation runs both ways. The panel below takes 5 well-known US splits and restates each one in the notation an Indian exchange circular would use, starting from a ₹10 share.

    concat(toString(toUInt32(argMax(split_to, execution_date))), '-for-',

    formatDateTime(max(execution_date), '%b %e, %Y')                 AS ex_date_label,

Apple's 4-for-1 split took effect on Aug 31, 2020. Filed in India, the same event would read as a face value cut from ₹10 to ₹2.5, with no ratio quoted anywhere in the announcement. The rupee column is the whole conversion: divide the old face value by the ratio, or divide the old face value by the new one to recover the ratio.

From ₹10 to ₹2: reading the ratio out of the notation

The ratios in circulation are a short list, so the translation is worth learning once. This panel counts whole-number split sizes in US corporate action records since 2015 and puts the matching face value beside each one, again starting from ₹10.

WITH split_events AS

    SELECT
        ticker,
        execution_date,

    FROM global_markets.stocks_splits
    WHERE execution_date >= '2015-01-01'

2-for-1 leads the list at 718 events, which lands a ₹10 face value at ₹5. The large ratios sit in the tail, and they are what produce the sub-rupee face values that turn up in filings: a ₹10 share taken below ₹1 has been divided more than ten ways.

The corporate action sequence the exchange runs

1. The board approves the split, names the new face value, and informs the exchange under the listing regulations.
2. Shareholders approve the change to the capital clause, usually by postal ballot.
3. The company fixes a record date and files it with the exchange, which publishes it in a corporate action circular.
4. The stock goes ex on that record date under the T+1 settlement cycle in force since early 2023. A buyer on the ex-date settles the following session and does not appear on the register for the entitlement.
5. NSDL and CDSL credit the additional shares to demat accounts, and the ISIN stays the same.

Two things a reader often expects to change do not. The ISIN, the twelve-character identifier for the security, survives a split untouched; new ISINs are issued for events such as a demerger. Paid-up capital survives too, since the face value fell by exactly the factor the share count rose by. No money has been raised. The existing equity has been divided into smaller units. The US version of this timeline is laid out in when a stock split takes effect, and the underlying mechanics in what a stock split is.

Why an unadjusted chart shows a crash that never happened

On the ex-date the quoted price falls by the split factor. That is the arithmetic of the event, not a loss of value: the holder's share count rises by the same factor in the same session. A price series that has not been restated for the split shows the fall as a vertical drop with nothing beside it to explain the shape.

Apple's split works as a pinned example, long settled and easy to check against the record. The panel is the stored daily close across the sessions on either side of the effective date, taken from a series that has already been restated for the split.

SELECT
    toString(date)                  AS session_date,
    round(toFloat64(any(close)), 2) AS close_usd
FROM global_markets.stocks_daily_aggs
WHERE ticker = 'AAPL'
  AND date >= '2020-08-24'
  AND date <= '2020-09-04'
GROUP BY date
ORDER BY date

The close printed $124.81 on the last session before the split took effect, then $129.04 on the first session after it. Both prints sit on the post-split basis, so the line runs across the effective date with no step in it. That is the restatement at work: every session before the split has already been divided by the split factor, and a chart built from raw quotes would instead carry those earlier sessions at the old, larger number and drop to this level overnight.

Adjusted history removes the step by dividing every pre-split price by the split factor, leaving a continuous series and a correct return across the date. Anyone setting a hypothetical ₹3,400 print from before a ₹10 to ₹2 split against a ₹700 print after it is comparing two different units of the same company. Split-adjusted price history covers how that restatement is applied and where it goes wrong.

What changes in the F&O segment

Single-stock futures and options over the name are adjusted on the same date the cash market goes ex. The exchange publishes an adjustment factor, the old face value divided by the new one. Strike prices of open contracts are divided by that factor. The market lot, which is the number of shares in one contract, is multiplied by it, and open positions are multiplied by it too. Contract value on either side of the adjustment matches, so exposure carries across the event rather than changing at it.

The revised lot size then stays in force until the exchange's next periodic review. A position held into an expiry week around a split date has two calendars running at once, the corporate action circular and the expiry schedule, and options expiry days in India sets out the second.

How often do splits happen?

Splits arrive unevenly. The panel counts corporate action records by year and separates forward splits from reverse splits, where a company consolidates many shares into fewer, larger ones. The Indian version of the second is a face value consolidation, ₹1 back to ₹10, running the same arithmetic in reverse.

SELECT
    toString(toYear(execution_date)) AS year,
    countIf(ratio > 1)               AS forward_splits,
    countIf(ratio < 1)               AS reverse_splits
FROM
(
    SELECT
        ticker,
        execution_date,
        any(toFloat64(split_to)) / any(toFloat64(split_from)) AS ratio
    FROM global_markets.stocks_splits
    WHERE execution_date >= '2015-01-01'
      AND execution_date <  toStartOfYear(today())
      AND split_from > 0
      AND split_to > 0
      AND ticker NOT IN ('SPCX')
    GROUP BY ticker, execution_date
)
GROUP BY year
ORDER BY year

In 2025, the last full year in the record, 424 forward splits and 1036 reverse splits took effect. The two counts track different populations: forward splits cluster among names whose share price has run up over the preceding year, while reverse splits concentrate in companies working to stay above an exchange's minimum price requirement. Upcoming stock splits keeps the forward calendar.

FAQ

Why is an Indian stock split announced as a face value change?

Indian company law records a par value for every share, and the split is executed as a reduction of that par value with a matching increase in the share count. The ratio is implied rather than stated: ₹10 to ₹2 is a 5-for-1.

Does a stock split change the ISIN in India?

No. A split leaves the ISIN unchanged, since the security itself is the same and only the number of units and the face value move. New ISINs are issued for events such as a demerger.

What is the ex-date for a stock split in India?

Under the T+1 settlement cycle, the ex-date falls on the record date itself. From that session the stock quotes on the new face value, and a buyer on the ex-date settles the next day, after the register has closed for the entitlement.

Do I lose money when a stock I hold splits?

No. The share count rises by the same factor the price falls by, so the value of the holding at the moment of the split is unchanged. The per-share cost of acquisition is restated on that same ratio.

What happens to my options when the underlying splits?

The exchange publishes an adjustment factor. Strike prices of open contracts are divided by it, and lot sizes and open positions are multiplied by it, leaving contract value the same on either side.
