What Is an Underlying Asset? Meaning, Types and Examples

A share, an option on that share and a fund holding it are different investments. Their values may be connected, but what you own and how your returns are calculated can differ. Understanding the underlying asset helps you identify the market exposure behind an investment before comparing its price, features or returns.

Underlying asset meaning

An underlying asset is the asset or reference on which a financial derivative is based. A derivative is a contract whose value or payments depend on that reference.

For a stock option, the underlying is the specified share; for an index derivative, it is the specified index. Contract documents may call it the underlying instrument or simply the underlying. When the reference is a share or another security, it may also be called the underlying security.

The term extends beyond physical assets. An exchange rate, interest rate or index can also be used to calculate contractual payments.

Types of underlying assets and examples

The underlying identifies the market exposure a contract represents:

Availability depends on the market and product. A category appearing in this table does not mean every related asset has a tradable derivative.

For Nifty 50 futures and options, the underlying is the Nifty 50 index. Its constituent shares contribute to the index calculation, but buying the derivative does not give you direct ownership of those shares.

Gold and silver can also serve as underlying assets. Their contracts specify features such as quantity, quality and settlement arrangements.

How does an underlying asset work in derivatives?

A derivative identifies its underlying and specifies how that reference affects the parties’ rights, obligations or payments.

The relationship varies by instrument:

• Futures and forwards: Create obligations under agreed terms for a future transaction or settlement.
• Call options: Give the buyer a contractual right linked to buying the underlying or receiving the applicable cash settlement.
• Put options: Give the buyer a contractual right linked to selling the underlying or receiving the applicable cash settlement.
• Swaps: Exchange payment streams that may depend on rates or other specified references.

The settlement method explains how the contract’s obligations are fulfilled. Cash settlement exchanges money calculated under the contract’s terms, while physical or delivery settlement involves transferring the specified underlying. Check the settlement method alongside the underlying, quantity and expiry rather than assuming every derivative results in asset delivery.

Underlying price, strike price and premium

These terms describe different values:

• Underlying price: The current price or value of the contract’s reference, such as a share price or index level.
• Spot price: The cash-market price of an asset for immediate transaction or delivery, where applicable.
• Strike price: The price specified for exercising an option or calculating its exercise payoff.
• Premium: The price paid to buy the option.

An index has a quoted level rather than a physical asset you can purchase directly. A futures price can also differ from the underlying’s current cash-market price.

Do the underlying and derivative always move together?

Not in the same direction or by the same amount. With other factors unchanged, a rising share price generally supports a call option’s value, while a falling price generally supports a put’s value. An option’s price also reflects:

• Its strike price.
• Time remaining until expiry.
• Expected volatility.
• Interest rates and expected dividends.

An option can therefore lose value even when the underlying moves in the direction its buyer expected.

Example of an underlying asset in a stock option

Consider a hypothetical share trading at ₹100. An investor buys a call option on it with:

• Strike price: ₹105.
• Premium paid: ₹3 per share.

The share is the underlying asset, while the call option is the derivative.

If the share reaches ₹115 at expiry, the call’s intrinsic value is:

₹115 − ₹105 = ₹10 per share

After deducting the ₹3 premium, the option’s profit is ₹7 per share, before other costs and taxes. The call’s breakeven price at expiry is ₹108 per share: the ₹105 strike price plus the ₹3 premium. At that price, its ₹3 intrinsic value equals the premium paid, before other costs and taxes.

If held to expiry when the share price is at or below ₹105, the call has no intrinsic value, and the buyer loses the premium paid. These are expiry payoff calculations per share. Actual contracts have specified lot sizes, exercise terms and settlement requirements.

Underlying assets in mutual funds and ETFs

In fund discussions, “underlying assets” usually means the investments held in the portfolio. This differs from the reference specified in a derivative contract.

Mutual funds

An equity fund invests mainly in shares, while a debt fund holds debt instruments according to its mandate. The holdings contribute to the fund’s net asset value, or NAV. NAV reflects the value of its assets after subtracting liabilities, divided by the number of outstanding units.

Portfolio weights matter: the same percentage price change generally has a greater effect in a large holding than in a small one, with other factors unchanged. Income, expenses and movements in other holdings also influence the result.

ETFs

An ETF gives you units in a fund whose investments provide its intended exposure. For an index-tracking ETF, distinguish:

• Benchmark: The index whose performance the fund seeks to track.
• Holdings: The securities and other permitted assets used to provide that exposure.
• Trading price: The price at which ETF units change hands on the exchange.

The ETF’s market price can be above or below its NAV. Knowing the benchmark alone therefore does not explain the price you pay or the return you receive.

What affects an underlying asset’s value?

The main drivers depend on the asset:

• Shares: Company earnings, business developments, valuations and market expectations.
• Bonds: Market yields, repayment expectations and the security’s terms.
• Commodities: Supply, demand, inventories and production conditions.
• Currencies: Interest-rate differences, economic conditions and currency demand.
• Indices: Constituent values and weights under the index methodology.
• Interest-rate benchmarks: Conditions affecting the market or transactions the benchmark measures.

Keep these drivers separate from the product’s features. Understanding a company’s prospects, for example, does not explain an option’s premium, expiry or payoff.

Risks linked to the underlying and the derivative

The investment structure affects how you experience movements in the underlying:

• Price movements: Changes in the underlying affect the position according to the contract’s payoff and pricing features.
• Liquidity: Trading activity in the underlying and the derivative can differ, so check how easily each can be bought or sold.
• Leverage: A derivative can represent exposure larger than the premium or margin initially paid.
• Contract obligations: Expiry, exercise, settlement and margin requirements affect how the position is managed.

For futures, the initial margin should not be treated as the maximum possible loss.

Why underlying assets matter for investors

Identifying the underlying helps you:

• Understand exposure: See which company, market, commodity or rate influences the investment.
• Compare products: Recognise how direct ownership, derivatives and funds provide different exposure to the same market.
• Assess a hedge: Check whether the contract matches the exposure you want to manage.
• Read beyond a label: Connect a product’s value with its reference, holdings and terms.

For derivatives, also review contract size, expiry, settlement and payment obligations. For funds, check the portfolio, investment mandate and expenses. The underlying explains part of the investment, while these details explain how you participate in it.

Conclusion

Understanding the underlying asset helps you connect an investment with the market exposure behind it. Identify the underlying instrument, then examine the contract or portfolio, costs and ownership arrangement. This makes it easier to compare products that refer to the same market but behave differently.

FAQs

Can every share have futures and options contracts?

No. Exchanges specify which securities are eligible as derivatives underlyings. Check the current exchange list and contract specifications rather than assuming every listed share has futures or options.

Can a derivative have another derivative as its underlying?

Yes. Some commodity options reference futures contracts rather than spot commodity prices. For example, NSE specifies gold options that use gold futures as their underlying.

Does buying a stock option give me dividends or voting rights?

No. Holding a stock option does not give you the shareholder rights attached to owning the shares. Those rights depend on share ownership and the applicable eligibility requirements.

Is an underlying asset the same as collateral?

No. The underlying determines the contract’s reference value or payments. Collateral supports margin or other obligations and may consist of different assets from the underlying.
