Calls and Puts
Every options question on the SIE starts with one fundamental distinction: is it a call or a put? Master this, and the rest of options falls into place.
What Is an Option?
- An option is a contract that gives one party the right (but not the obligation) to buy or sell a security at a specific price within a specific time
- Two parties to every option contract: the buyer (holder) and the seller (writer)
- The buyer pays a premium to the seller for the contract
- Options are derivatives: their value is derived from an underlying security
Call Options
A call option gives the holder the right to BUY the underlying security at the strike price.
- Call buyer (holder): Pays the premium, profits when the price goes UP
- Call seller (writer): Receives the premium, is obligated to sell if assigned
- Bullish position: you buy a call when you think the stock will rise
Think of it this way: A call is like a reservation to buy. You lock in a purchase price, and if the market goes higher, you benefit.
Put Options
A put option gives the holder the right to SELL the underlying security at the strike price.
- Put buyer (holder): Pays the premium, profits when the price goes DOWN
- Put seller (writer): Receives the premium, is obligated to buy if assigned
- Bearish position: you buy a put when you think the stock will fall
Think of it this way: A put is like insurance on your stock. If the price drops, you can still sell at the strike price.
The Four Basic Positions
| Position | Right/Obligation | Market Outlook | Max Gain | Max Loss |
|---|---|---|---|---|
| Long call | Right to buy | Bullish | Unlimited | Premium paid |
| Short call | Obligation to sell | Bearish/neutral | Premium received | Unlimited (if uncovered) |
| Long put | Right to sell | Bearish | Strike price - premium | Premium paid |
| Short put | Obligation to buy | Bullish/neutral | Premium received | Strike price - premium |
Exam Tip: Gotchas
- A long put and a short call are both bearish, but they are not the same. A long put gives the right to sell (limited risk); a short call creates the obligation to sell (potentially unlimited risk). Same directional outlook, very different risk profiles.
- "Long" always means buyer; "short" always means seller, regardless of whether it is a call or a put.
The Buyer/Seller Divide
This is the single most important concept in options:
| Feature | Buyer (Holder) | Seller (Writer) |
|---|---|---|
| Pays or receives premium? | Pays premium | Receives premium |
| Has rights or obligations? | Rights | Obligations |
| Wants to exercise? | Yes (if profitable) | No (wants option to expire worthless) |
| Risk profile | Limited loss (premium) | Potentially unlimited loss |
Exam Tip: Gotchas
- Buyers have rights, sellers have obligations. This distinction drives every options question on the SIE. The buyer pays the premium for the right to act; the seller receives the premium and must perform if called upon.
