What Are Options — Options Tutorial

Forget the Textbook Definition

Most options tutorials open with: “An option is a financial derivative contract that gives the holder the right to buy or sell an underlying asset at a specified price within a specified time.”

You probably forgot that sentence already.

Try this instead — an option is an insurance policy. The buyer is the policyholder, the seller is the insurance company. The policyholder pays a premium for protection over a set period. If something goes wrong, the insurance company pays out; if nothing happens, the premium belongs to the insurer.

This isn’t just an analogy. It’s how options actually work. The buyer pays for a right; the seller collects money and takes on an obligation. Grasp this relationship, and everything else is detail.

Call Options: Locking In a Purchase Price

In Hong Kong’s real estate market, there used to be a concept called “buying on plans” (楼花). A developer sells a forward contract on an apartment — the buyer puts down a ¥100,000 deposit to lock in the right to purchase the property at ¥3,000,000 one year later.

If the property rises to ¥3,500,000? Exercise the right, buy at ¥3,000,000, net profit ¥400,000. If it drops to ¥2,000,000? Walk away. Nobody would pay ¥3,000,000 for something worth ¥2,000,000. The loss is limited to the ¥100,000 deposit.

That’s a call option in real life — pay a premium, lock in a future purchase price. The more the underlying rises, the more valuable this right becomes.

Now translate this to stocks. Boeing is trading at $223. You buy one call option with a $220 strike price and a $23.50 premium. One contract covers 100 shares, so total cost is $2,350.

Boeing climbs to $300 — your option profit is roughly $5,746, a 244% return. Buying the stock directly? 34%.

The difference is leverage — $2,350 gave you exposure to 100 shares of Boeing’s upside. Flip side: if Boeing drops below $220, the option expires worthless. $2,350, gone. Risk and reward, two sides of the same coin.

Put Options: Locking In a Selling Price

Governments sometimes guarantee minimum grain purchase prices for farmers. Say wheat is guaranteed at ¥3 per jin this year.

Three months later, demand surges and market price hits ¥5 — farmers sell on the open market for more. But if the market slumps to ¥2.50, farmers can still sell to the government at ¥3, locking in minimum income.

A put option works the same way. The holder gains the right to sell at a predetermined price. The more the underlying drops, the more valuable this right becomes.

Two types of options, one sentence each: Calls lock in your buying price. Puts lock in your selling price.

American vs. European: Movie Tickets and Mooncake Vouchers

Options also differ by when you can exercise.

American options are like mooncake vouchers — redeem any day before the Mid-Autumn Festival, as long as the store is open. You can exercise at any time before expiration.

European options are like movie tickets — a showing on September 1st means you can’t get in on August 31st, and the ticket is void on September 2nd. Exercise only on the expiration date.

In practice, nearly all US-listed equity options are American-style. You can exercise early, but most people don’t — selling the option on the market is usually better because the price still includes time value (covered in the next tutorial).

Five Things Options Can Do

Many people think options are only about “big bets with small money.” That’s one use out of five.

1. Risk Transfer: Insurance for Your Portfolio

Worried about a stock dropping? Buy a put option to lock in a minimum selling price. If the stock falls below the strike, the option covers you. If the stock keeps rising, you keep the upside.

This is the key difference from hedging with futures. Futures eliminate both downside risk and upside potential. Options only cap the downside — upside stays unlimited.

2. Leverage: Small Money, Big Exposure

In 2012, Soros deployed roughly $30 million in call options betting on the US dollar against the Japanese yen. The result: $1 billion in profit — a 30x return.

A double-edged sword. Right direction, multi-bagger returns. Wrong direction, premium goes to zero.

3. Income Enhancement: Collecting Rent on Your Shares

When a stock you own is going sideways, sell call options against it to collect premiums — like renting out a property you own. This is the Covered Call strategy, which we’ll cover in detail later.

4. Multi-Dimensional Trading: Beyond Up or Down

Stocks only: you make money when prices go up — one dimension. Add futures: profit from both up and down moves — two dimensions. Add options: profit from sideways consolidation, or from big moves in either direction — three dimensions.

As long as you have a view, there’s an options strategy for it.

5. Precision: Better Predictions, Better Returns

Four investors are all bullish on a stock index. A just thinks it’ll go up. B predicts it’ll rise within 10 days. C believes it’ll rise more than 5%. D estimates a 5-10% gain.

Ten days later, the index is up 6.56%.

Without options, all four buy the stock and earn the same 6.56%. With options: A earns 6.56%, B earns 234%, C earns 278%, D earns 374%. The more precise your prediction, the higher your return.

Exercise

Think of a scenario from your own experience: would you use a call or a put?

For example: you hold 1,000 shares of Apple before an earnings announcement and you’re worried about a crash. Should you buy a call or a put? Why? How much would you pay for this “insurance” — as a percentage of your position?
