F&O Lot Size List of Stocks and Indices in Indian Stock Market

In the Indian stock market, Futures and Options (F&O) trading requires a clear understanding of lot sizes, as they directly impact capital requirement, margin, and risk management. Every F&O stock has a predefined lot size set by the exchange, which traders must follow while placing trades.

In this blog post, you will find a A complete and updated list of all Futures & Options (F&O) stocks and indices in the Indian stock market with their latest lot sizes. This list will help both beginners and experienced traders plan their trades better, manage risk effectively, and make informed trading decisions.

Futures and Options (F&O) trading is an important segment of the Indian stock market that allows traders to speculate, hedge, or manage risk using derivative contracts. These contracts derive their value from underlying assets such as stocks and market indices and are actively traded on exchanges like the NSE.

One of the most important concepts in F&O trading is lot size. Lot size defines the minimum quantity that can be traded in a single futures or options contract. It directly impacts the margin requirement, capital usage, and risk exposure of every trade. Without understanding lot size, traders may miscalculate their investment and risk levels.

There is also a key difference between stock F&O and index F&O trading. Stock F&O contracts are based on individual company shares, and their lot sizes vary depending on the stock price and volatility. In contrast, index F&O contracts are based on market indices such as NIFTY and BANK NIFTY, usually offering more liquidity and relatively stable lot sizes.

Understanding these basics is essential before trading in the derivatives market, and this blog post aims to provide a complete and updated list of F&O stocks and indices along with their latest lot sizes to help traders plan their trades more effectively.

What Is Lot Size in F&O Trading?

In Futures & Options (F&O) trading, lot size refers to the fixed number of shares or units that form one F&O contract. Traders cannot buy or sell a single share in the derivatives segment; instead, they must trade in predefined lot sizes specified by the stock exchange.

For example, if a stock has a lot size of 500, one F&O contract will represent 500 shares of that stock. Similarly, index F&O contracts represent a fixed number of index units.

🔸 Meaning of Lot Size

Lot size is set by the exchange to standardize trading and manage risk in the derivatives market. It ensures uniform contract values and helps maintain liquidity across F&O instruments.

🔸 How Lot Size Affects Trading

🔹 Margin Requirement

Lot size directly affects the margin required to place an F&O trade. A higher lot size means a larger contract value, which increases the margin needed. Traders must always calculate margin based on the current lot size before entering a position.

🔹 Risk & Reward

Since price movement is applied to the entire lot, profit and loss are calculated on the full contract size. Larger lot sizes result in higher potential gains as well as higher losses. Understanding lot size helps traders control their risk exposure effectively.

🔹 Capital Planning

Lot size plays a crucial role in capital planning. Traders can decide how many lots to trade based on available capital, risk tolerance, and diversification strategy. Proper planning helps avoid over-leveraging and improves long-term trading discipline.

Why Lot Size Changes?

Lot sizes in Futures & Options (F&O) trading are not fixed permanently and may be revised by the stock exchange from time to time. These changes are mainly introduced to maintain market stability, manage risk, and ensure fair participation for traders. Below are the key reasons why lot sizes are revised.

🔸 SEBI & Exchange Rules

SEBI and stock exchanges like NSE regularly review F&O contracts to ensure orderly market functioning. Based on regulatory guidelines, exchanges may revise lot sizes to control excessive speculation, reduce risk concentration, and protect retail traders from high exposure.

🔸 Contract Value Standardization

One of the main reasons for lot size changes is standardization of contract value. Exchanges aim to keep the F&O contract value within a predefined range. If a stock price rises or falls significantly over time, the lot size is adjusted so that the overall contract value remains balanced and accessible to traders.

🔸 Volatility & Price Movement

High volatility or sharp price movements in a stock or index can increase trading risk. To manage this, exchanges may reduce or increase the lot size depending on price behavior and liquidity. This helps in maintaining stable trading conditions and prevents sudden large losses due to excessive exposure.

How to Use Lot Size for Trade Planning

Understanding lot size is essential for effective trade planning in Futures and Options (F&O) trading. Proper use of lot size helps traders control risk, manage capital efficiently, and avoid overexposure. Below are the key ways lot size should be used while planning trades.

🔸 Position Sizing

Lot size determines the minimum quantity you can trade in F&O. Before entering a trade, always calculate how many lots fit within your risk appetite and available capital. Avoid trading excessive lots, as it can significantly increase potential losses.

🔸 Margin Calculation

Each F&O contract requires a specific margin, which depends on the lot size and underlying price. Knowing the exact lot size helps traders estimate margin requirements in advance and ensures sufficient funds are available before placing trades.

🔸 Risk Management

Lot size directly impacts your risk per trade. A larger lot size means higher exposure to price movement. Traders should always align lot size with their stop-loss levels and overall risk management strategy to limit downside risk.

🔸 Capital Allocation

Proper capital allocation becomes easier when you understand lot sizes. Traders can decide how much capital to allocate to a single trade or across multiple positions, helping maintain portfolio balance and reduce unnecessary risk.

🔔 Pro Tip

Never choose a trade based only on profit potential. Always consider lot size, margin requirement, and risk exposure together before entering any F&O position.

Important Points Traders Must Know

Before trading in Futures & Options (F&O), it is essential to understand a few key points related to lot sizes and contract specifications. These points can help traders avoid costly mistakes and trade more responsibly.

🔸 Lot Size Is Mandatory

In F&O trading, orders must be placed in multiples of the defined lot size. Unlike the cash market, partial quantities are not allowed. Always double-check the lot size before placing any order.

🔸 Lot Sizes May Change

F&O lot sizes are revised periodically by the exchange. Traders should stay updated with the latest changes, especially during contract revisions, to avoid confusion and incorrect trade calculations.

🔸 Difference Between Stock & Index Lot Sizes

Index F&O contracts generally have fixed and smaller lot sizes compared to stock F&O contracts. Stock lot sizes vary depending on the share price and volatility, which directly affects margin requirements.

🔸 Futures and Options Lot Sizes Are the Same

For a given stock or index, the lot size remains the same for both futures and options contracts. Only the premium and margin requirements differ.

🔸 Weekly vs Monthly Index Contracts

Index options may have weekly and monthly expiries, but the lot size remains unchanged across different expiry cycles. Traders should not confuse expiry type with lot size.

🔸 Always Verify Before Trading

Always confirm the latest lot size from official sources such as the NSE website or your broker’s trading platform before placing a trade, especially after major market movements or regulatory updates.
