Breaking Down the Options Contract Example
Consider this scenario:
On December 23, investor Zhang Baiyun buys 3 contracts of 300ETF Call January 4000 at a price of 888 yuan per contract, spending a total of 2,664 yuan.
For beginners, phrases like “300ETF Call January 4000” can be confusing. But by dissecting the name, we uncover the core structure of any options contract. This process helps clarify exactly what is being traded.
The full contract title reveals four fundamental attributes:
- Underlying Asset
- Contract Type (Call or Put)
- Expiration Month
- Strike Price
These are embedded directly in the contract name and are critical to understanding your position before placing a trade.
Core Elements of an Options Contract
1. Underlying Asset
The underlying asset is the financial instrument that the option gives you the right to buy or sell. In our example, it’s the CSI 300 ETF, a fund tracking the performance of 300 large-cap stocks listed on the Shanghai and Shenzhen exchanges.
Knowing the underlying allows you to assess market exposure and volatility, which directly affect pricing and risk.
2. Contract Type: Call vs. Put
Options come in two types:
- Call Option: Gives the holder the right to buy the underlying at a set price before expiration.
- Put Option: Grants the right to sell the underlying under the same conditions.
In this case, “Call” means Zhang Baiyun has the right to purchase CSI 300 ETF shares at 4.00 yuan per share (more on that below), regardless of how high the market price climbs.

3. Expiration Month
This indicates when the option expires—its final valid date. Here, "January" refers to the January expiration cycle. Most ETF options have weekly and monthly expirations, allowing traders flexibility based on their outlook.
Time decay accelerates as expiration approaches, so choosing the right term is crucial for strategy success.
4. Strike Price
The strike price is the predetermined price at which the underlying can be bought (call) or sold (put). "4000" represents a strike price of 4.00 yuan per ETF unit (multiplied by 10,000 units per contract).
If the market price exceeds 4.00 yuan by expiration, the call option becomes profitable for the buyer.
Additional Key Features You Should Know
Beyond the basics shown in the contract name, several other important terms shape your trading experience.
5. Contract Multiplier (Contract Unit)
Each options contract controls a specific number of underlying units. For all currently listed ETF options in China, including CSI 300 ETF, SSE 50 ETF, and CSI 500 ETF, the contract multiplier is 10,000 units.
So, if Zhang Baiyun holds 3 contracts, he controls:
10,000 units × 3 = 30,000 ETF shares
This multiplier significantly impacts both potential profit and required capital for exercise.
6. Premium (Option Price)
The premium is what the buyer pays to acquire the option rights. It's essentially the market price of the contract.
Zhang Baiyun paid 888 yuan per contract, totaling:
888 × 3 = 2,664 yuan
As an option buyer, his maximum possible loss is limited to this premium. No matter how far the market moves against him, he won't lose more than what he paid—making options attractive for risk-defined strategies.
Sellers (writers), however, take on greater risk in exchange for collecting premiums upfront.
7. Expiration Date, Last Trading Day & Exercise Dates
These dates are closely linked:
- Expiration Date (E-day): Final day the contract is valid.
- Last Trading Day (E-day): Last opportunity to close or trade the position.
- Exercise Date (E-day): Day when buyers can request to exercise their right.
- Settlement/Receipt Date (E+1): When actual delivery occurs—one business day after exercise for ETF options.
Currently, for domestic ETF options:
Expiration = Last Trading Day = Exercise Day
Settlement → Next trading day (E+1)
Timing precision matters—especially near expiry week.
8. Exercise Style
There are two main exercise styles:
- American-style: Can be exercised anytime before expiry.
- European-style: Only exercisable on the expiration day.
All existing ETF options in China use European-style exercise, meaning investors must wait until expiration day to act—even if deep in-the-money earlier.
This affects early assignment risk and exit planning.
9. Settlement Method
Most ETF options use physical delivery, though cash settlement may occur under exceptional circumstances.
Here’s how physical delivery works:
- Call Option Exercise: Buyer must pay strike price × quantity; seller delivers corresponding ETF shares.
- Put Option Exercise: Buyer delivers ETF shares; seller pays strike price amount.
For Zhang Baiyun’s call option:
If he exercises, he must pay:
4.00 yuan × 30,000 shares = 120,000 yuan
In return, he receives:
30,000 shares of CSI 300 ETF
Ensure sufficient funds or holdings are available if planning to exercise.
Frequently Asked Questions (FAQs)
Q: What happens if I don’t close my option before expiration?
A: If your option is in-the-money by even a small margin, it will typically be automatically exercised unless you opt out. Out-of-the-money options expire worthless.
Q: Can I exercise an ETF option early?
A: No—since Chinese ETF options are European-style, early exercise isn’t allowed. You must wait until expiration day.
Q: How much capital do I need to exercise a call option?
A: Multiply the strike price by the number of underlying units (contract multiplier × number of contracts). Ensure liquidity is available in your account.
Q: Is there a fee for exercising an option?
A: Yes—brokerage commissions and settlement fees may apply. Check with your provider for exact costs.
Q: Why does contract size matter?
A: Because each contract controls 10,000 units, small price movements can lead to large gains or losses in value—amplifying both opportunity and risk.
