NSE F&O Lot Size List — Stocks & Indices

The current lot size of every F&O stock and index, the rupee value of one lot, and how lot sizes work - straight from NSE's F&O bhavcopy.

One F&O contract on NSE isn't one share or one index point. It's a fixed number of units of the underlying, called the lot size. Every futures and options order on NSE is for a whole number of lots - there are no fractional contracts.

The table above lists the current lot for every stock and index in the F&O segment, read from NSE's F&O bhavcopy for the latest session, so it changes the day NSE revises a lot. It also shows what one lot is worth in rupees at the last underlying price, which is the number that matters for position sizing.

How NSE sets lot sizes

NSE sizes each contract so that one lot represents a meaningful rupee value of the underlying, within bands set by SEBI. A cheaper stock therefore needs a larger lot and an expensive one a smaller lot - compare the value-of-one-lot column across the table and you'll see the values cluster even though the lots differ widely.

Index contracts sit at the higher end: SEBI raised the minimum contract value for index derivatives in late 2024, which is why index lots look large relative to the index level. The table's value column shows where each contract actually stands today.

When lot sizes change

NSE reviews lot sizes periodically and revises them when prices have drifted far enough that a contract's value leaves its band. Revisions usually apply from a specified expiry, so for a while the near-month and later contracts can carry different lots - the table shows each expiry's lot when they differ.

Corporate actions change lots too. After a split or a bonus issue, NSE adjusts the lot (and the strike prices of open option contracts) so that the economic value of existing positions is unchanged.

Why lot sizes matter for position sizing

Your smallest possible position is one lot. Multiply the lot by the price to see the real exposure: a one-point move in the underlying changes the value of one lot by the lot size in rupees, and a 1% move changes it by 1% of the value-of-one-lot column.

For option buyers, the cash outlay is the premium times the lot, but the exposure to the underlying is the full value of the lot. For option sellers and futures traders, the broker blocks margin on that full exposure, which is typically many times the premium. Check your broker's margin calculator before placing the trade.
