Welcome to the Pack — What an Option Is, and Isn’t

An old wolf teaching a young wolf under moonlight

"The first thing I learned, kid: an option gives you a right, not an obligation. But be careful — some buy the obligation instead of the right. This whole book is built on you understanding that difference."

A Story: The Neighbor’s Orchard

I had a neighbor once. He kept a vineyard, a vine-shaded chair, and an old apricot tree. One spring morning he said:

"Look. I don’t know if the apricots will hold this year. If they do, a crate will be worth real money. Here’s my offer: give me $50 now, and in three months you have the right to buy a crate from me for $150. If the crop fails, the $50 stays with me, and you walk away — you are not obliged to buy."

I thought about it. The day was warm; the leaves looked thick. I gave him fifty dollars.

Three months later the harvest exploded. Crates were selling for $280. I walked into the orchard, bought my crate for $150, sold it in the market for $280. Out went $50 (the option), out went $150 (the crate), in came $280. I cleared $80.

That was the first option trade of my life. Year 1992. And if the apricots had failed, the fifty dollars would have stayed in his pocket.

That is what an option is. The rest is decoration.

The Definition — I Am Not Telling You Anything New

An option contract is an agreement between two parties:

  • The buyer (long) — pays a price (the premium) to acquire a right. The right to buy or sell a specific asset, at a specific price, by (or on) a specific date.

  • The seller (short) — receives the premium and in exchange takes on an obligation. If the buyer exercises the right, the seller must honor it.

The buyer says: "I do not have to use my right, but I may."

The seller says: "If the buyer chooses to use it, I must deliver."

This asymmetry is the heart of every option. Miss it, and you miss the book (Hull, 2018, Ch 10).

Buyer = right. Seller = obligation.

If you are the buyer, the worst that can happen is you lose what you paid.
If you are the seller, the worst — in some strategies — is theoretically unlimited loss.

We will see this in full and unforgiving form in Chapter 5. For now, etch this into a corner of your mind: selling an option is not the mirror image of buying one.

Two Kinds of Options: Calls and Puts

There are exactly two basic types. Every combination, every strategy, every fancy-sounding name in the rest of this book is built on these two.

The Call Option — "Right to Buy"

A call gives you the right to buy a specific asset at a specific price.

  • My neighbor’s apricot deal was a call. I paid for the right to buy a crate at $150.

  • Buy one AAPL call and you have the right to buy AAPL at a specific price.

When does a call’s value rise? When the underlying goes up. When apricots hit $280, my right to buy at $150 became valuable. If they had fallen to $100, my right to buy at $150 would have been worthless — I could buy them in the open market for $100, so why pay $150?

The Put Option — "Right to Sell"

A put gives you the right to sell a specific asset at a specific price.

  • Buy one AAPL put and you have the right to sell AAPL at a specific price.

  • You do not need to own AAPL to exercise — you would simply buy and immediately deliver, or close the position for the gain.

When does a put’s value rise? When the underlying goes down. If my put strike is $100 and the stock falls to $60, I can buy at $60 and force someone to take it from me at $100. Valuable. If the stock rose to $200, my right to sell at $100 would be worthless.

A Memory Trick

Call = call it to you = stock comes toward you = bet up

Put = put it to someone = stock goes away from you = bet down

New wolves confuse these for the first two months. By the third month, they would not confuse them in a dream.

The Parts of an Option

Every option contract has four fundamental components, and one that is invisible until it bites you (Hull, 2018, Ch 10).

Component Description

Underlying

What asset? AAPL? SPY? TSLA?

Strike Price

The "specific price" we keep mentioning. In the apricot story, $150. For AAPL, $175 perhaps.

Expiration (Expiry)

The last date the right is valid. After this date, the option is either exercised or expires worthless.

Premium

The price of the right. $50 in the apricot story. On the exchange, you see this quoted as a per-share number.

And the invisible part:

  • Contract Multiplier — every US-listed equity option contract represents 100 shares of the underlying (OCC, Characteristics and Risks). So if you buy one AAPL call with a quoted premium of $2.50, your real cost is $2.50 × 100 = $250 per contract (before commissions and the bid-ask).

The most common mistake new wolves make: they see a premium quoted at $1.20 and think "cheap" and click buy. No. $1.20 × 100 = $120 per contract. Three contracts = $360 of capital at risk. This single detail has wiped out more young accounts than I care to count. Premium is always quoted per share, and always multiplied by 100 per contract.

Three Positions Relative to the Strike: ITM, ATM, OTM

Now the vocabulary. You must learn this, because it appears in every line that follows.

Suppose AAPL is trading at $175.

Position For a Call For a Put

ITM
(In-the-Money)
"In the money"

Strike < $175
e.g. $170 call
If exercised now, profit

Strike > $175
e.g. $180 put
If exercised now, profit

ATM
(At-the-Money)
"At the money"

Strike ≈ $175

Strike ≈ $175

OTM
(Out-of-the-Money)
"Out of the money"

Strike > $175
e.g. $180 call
If exercised now, loss

Strike < $175
e.g. $170 put
If exercised now, loss

The relationship between these three positions is taken apart in Chapter 4 — where the difference between intrinsic and extrinsic value lives.

For now, hold this:

"Out-of-the-money options are cheap. If they hit, they multiply."
— every second tweet you will read on this subject

Yes, OTM is cheap. Yes, if it hits, it multiplies. No, most OTM options do not hit. Industry data show roughly 70-80% of OTM options held to expiry finish worthless (OCC; Sinclair, 2013). Etch this number in too. We will revisit it in Chapter 5.

American vs European: The Right to Exercise Early

Almost all US-listed equity options are American-style (OCC, Characteristics and Risks). This is a technical detail with practical teeth.

  • American-style: The buyer may exercise on any business day up to and including expiration.

  • European-style: The buyer may exercise only on the expiration date.

In the US, equity options on individual stocks and ETFs (SPY, QQQ, IWM) are American. Major index options (SPX, NDX, RUT) are European. Cash-settled vs physically-settled is a related distinction we will meet in Chapter 9.

American-style matters most when you are the seller of an option. The buyer can hand you the underlying any morning. Calls go in for early exercise most often the day before an ex-dividend date, because the dividend can be larger than the remaining time value of the call (Hull, 2018, Ch 15). This is covered in detail in Chapter 9, "Dark Scenarios."

A Breath: What Have You Learned So Far?

Close the book for a moment. Can you list these in your head?

  1. The option buyer gets a right. The seller takes on an obligation.

  2. Call = right to buy = bet up.

  3. Put = right to sell = bet down.

  4. Every option has four parts: underlying, strike, expiry, premium.

  5. In the US, each equity option contract represents 100 shares. Multiply the quoted premium by 100.

  6. ITM = in the money. ATM = at the money. OTM = out of the money.

  7. US equity options are American-style — they can be exercised early.

If yes, turn the page. If not, read this chapter again. Slowly. There is no rush.

A Scar — The Story That Is About Me

The year was 2003. Cisco (CSCO) was clawing its way back from the dot-com wreckage. Years before, I had burned with the rest of them, but Cisco had survived. The stock was around $18. "This time I’m in," I told myself — and made one mistake. Then another on top of it.

Instead of buying the stock, I bought out-of-the-money calls because they were cheap: the $25 strike, two months out, premium $0.40. Twenty-five contracts. $1,000 of capital at risk. My thinking: "If the stock hits $25, I have the right to buy 2,500 shares at $25 — sell them, profit."

Two months later the stock was $19.50. It had moved up. But not enough. My options expired worthless. $1,000 to zero.

The deeper wound: if I had simply bought the stock with that $1,000, I would have owned about fifty shares at $18, watched them rise to $19.50, and ended up with $75 of profit. A modest, real, unromantic $75.

Buying out-of-the-money calls is not just a direction bet. It is a bet on direction + magnitude + time, all three at once. I had to be right about all three. Direction alone was not enough. None of them was wrong individually — but I had to be right about all three together.

That is how an option differs from a stock. That is the whole sentence.

Before You Click Buy — Your First Checklist

The first checklist of the book. You will see one at the end of every strategy chapter from here on.

You are not opening a trade yet — you are still introducing yourself. But test your understanding:

[ ] Can I say in one sentence the difference between a call and a put?

[ ] Do I understand the asymmetry of risk between buyer and seller?

[ ] Can I name the four parts of an option?

[ ] Do I know how to translate a quoted premium into the actual cost of a contract (× 100)?

[ ] Do the terms ITM, ATM, OTM live in my head?

[ ] Do I understand what American-style means, and why early exercise risk matters to a seller?

Six "yes" answers → turn the page. One "no" → back to the chapter.

Next Chapter

Before the Greeks, before the math, before the strategies — a chapter on who’s on the other side of every trade. Chapter 2 introduces the participants: retail, market makers, hedge funds, banks, dealers, hedgers. Knowing them changes how you read every quote on your screen.

After that, Chapter 3 meets the Greeks: five characters who explain the soul of an option.
