Call Option Essentials: Remember the Main Features of Options Contract Types

Introduction — Hook + Friendly Definition

If you want to pass the CIRE and trade options like a pro, you must get one thing crystal clear: what a call option is and how option contracts work in Canada. A call option gives you the right, but not the obligation, to buy the underlying asset at the strike price before or at expiry. The writer (seller) of that call takes on the obligation to sell the underlying at the strike if you exercise. Simple in definition, but the contract mechanics determine the pricing, exercise incentives and exam traps you must avoid.

(For official Canadian contract rules see the Montréal Exchange guide and the CDCC exercise/assignment disclosures.)

Core Concepts (Recall) — Must-know facts

• Call option: holder has the right to buy at the strike; writer must sell if exercised.
• Put option: holder has the right to sell at the strike; writer must buy if exercised.
• Standard Canadian listed equity option contracts usually cover 100 shares; premiums are quoted per share. Multiply the quoted premium by the contract multiplier (commonly ×100) to get the contract-dollar value.
• Premium = intrinsic value + time (extrinsic) value.
• Intrinsic value formulas: call = max(0, spot − strike); put = max(0, strike − spot).
• Time value reflects time to expiry, volatility, interest rates and expected dividends and decays toward expiry (theta).
• American-style options: exercise any time up to and including expiry. European-style: exercise only at the specified time (usually at expiry).
• Canadian expiry convention: exercise possible up to and including the third Friday of the expiry month; the contract expires on the Saturday following that third Friday. (See Montréal Exchange.)

Detailed Analysis (Understand) — The Why and How

Pricing and exercise incentives flow from the premium decomposition. Suppose you buy 1 ABC APR 50 call while ABC trades at $52 and the quoted premium is $2.10. Intrinsic value per share = $52 − $50 = $2.00; time value per share = $2.10 − $2.00 = $0.10. Contract cost = $2.10 × 100 = $210. That intrinsic/time split explains why deeply in-the-money calls trade with little time value and why early exercise might be optimal.

American-style options introduce early-exercise risk for writers because holders can exercise any time. For calls on dividend-paying stocks, a classic rational early exercise is to capture an upcoming dividend when the dividend amount exceeds the remaining time value you would forfeit by exercising early. For puts, early exercise yields immediate proceeds, but selling the underlying in the market is often preferable when liquidity exists. These practical assignment mechanics and margin impacts are explained in CDCC disclosures and FINRA guidance on assignment and settlement.

Remember: the premium is the full price of the option right — not a down payment on shares. Also convert quoted per-share premiums to contract-dollar amounts using the multiplier (commonly 100) before answering exam calculations.

Practical Application — Real-world scenarios for professionals

• Suitability & execution: When recommending a covered-call strategy, you must account for the contract multiplier and expiry convention so clients understand proceeds and assignment timing.
• Dividend capture decisions: If a call is deep in-the-money and the ex-dividend date is imminent, compute lost time value vs. dividend to decide on early exercise.
• Clearing & margin: An exercised call triggers assignment and delivery obligations that affect writers’ margin; consult CDCC procedures for settlement specifics.
• Exam practice: Convert per-share quotes to contract dollars (premium × 100) and apply intrinsic/time-value formulas to justify exercise choices.

Key Takeaways

• A call option gives the holder the right to buy at the strike; the writer must sell on exercise.
• Premium = intrinsic + time value; intrinsic for calls is max(0, spot − strike).
• Standard Canadian equity option = 100 shares; quoted premiums are per share — multiply by 100.
• American-style permits early exercise; European-style does not.
• Canadian expiry: exercise through the third Friday; contract expires the following Saturday.

Master these basics and you’ll avoid common exam pitfalls and be better prepared for real-world trading and compliance decisions.
