📘 How Options Contracts Work

An option is not a share of stock. It is a time-limited contract: the buyer gets a right, the seller takes an obligation, and both sides trade premium for that asymmetry.

What you’ll learn

  1. Contract and rightsIdentify an option's underlying, strike, expiration, and distinguish call and put rights.Options trade time-limited rights and obligations; calls control purchase, puts control sale.
  2. Premium and payoffExplain premium, intrinsic and time value, expiration diagrams, and short-option risk.Premium sets entry cost; payoff diagrams show exercise value while writers face assignment obligations.
  3. Risk and useUse a checklist to connect an option position to timing, payoff, assignment, and risk.A defined question and explicit risk checklist are essential before evaluating an options position.

Questions this course answers

What does an option buyer receive?

The holder receives a contractual right; the writer takes the corresponding obligation if exercise or assignment occurs.

What right does a put buyer have?

A put gives its holder a sale right at the strike, subject to the contract's exercise and expiration terms.

Why can an option move in the expected direction and still lose money?

Profit includes the premium and depends on magnitude, timing, volatility, and other pricing factors.

Ignoring fees, what is the approximate break-even for a long call?

A call buyer needs the underlying to exceed the strike by enough to recover the premium.

What is a central risk for an uncovered short call?

An uncovered call writer may need to deliver shares at the strike while buying them at a much higher market price.
