Derivatives
What Are Derivatives?
A derivative is a financial contract whose value is “derived” from something else — usually an underlying asset such as:
- A stock (e.g., Apple)
- A bond or interest rate
- A commodity (e.g., oil, gold, wheat)
- A currency (e.g., USD/EUR)
- Or even an index (e.g., S&P 500)
Think of a derivative as a bet or agreement about how the price of something will move in the future.
Common Types of Derivatives
| Type | Description | Example |
|---|---|---|
| Forward | A private agreement to buy/sell something at a fixed price in the future. | Farmer agrees to sell 1000 tons of wheat to a bakery in 6 months at $300/ton. |
| Futures | Like a forward, but traded on an exchange (standardized and regulated). | Oil futures, gold futures, stock index futures. |
| Options | Give the right, but not the obligation, to buy (call) or sell (put) an asset at a set price before/at a certain date. | Buy a “call option” on Tesla stock at $200 strike price. |
| Swaps | Two parties exchange cash flows based on different financial variables. | Interest rate swap: one pays fixed rate, the other pays floating rate. |
| Credit Default Swaps (CDS) | A form of insurance against a bond default. | Bill Ackman’s 2020 trade used CDS — he paid premiums to get protection if corporate bonds defaulted. |
Why Derivatives Exist
Derivatives are powerful tools used for:
1. Hedging (Risk Management)
Used to protect against future price changes.
Example: An airline uses oil futures to lock in jet fuel prices so rising oil doesn’t hurt profits.
2. Speculation (Profit from Movements)
Traders bet on future price movements to make profits.
Example: Buying a call option on gold expecting its price to rise.
3. Arbitrage
Take advantage of small price differences in different markets for risk-free profit.
Example: Buying gold in London and selling it simultaneously in New York if prices differ slightly.
4. Access or Leverage
Derivatives let you control large positions with smaller amounts of money (leverage).
Example: With $1,000, you can buy call options controlling $10,000 worth of stock.
Risks of Derivatives
| Risk Type | Description |
|---|---|
| Leverage risk | Small price movements can cause large gains — or losses. |
| Counterparty risk | If the other party defaults, you may lose money (especially with OTC derivatives). |
| Complexity | Some structures (like synthetic CDOs) are extremely complex and hard to value. |
| Liquidity risk | Some derivatives can’t be sold easily when markets panic. |
| Systemic risk | Large interconnected derivatives positions can cause financial crises (e.g., 2008 meltdown). |
Real-World Examples
| Case | Derivative Type | Purpose / Outcome |
|---|---|---|
| Bill Ackman (2020) | Credit Default Swaps | Hedge corporate bond risk — turned $27M → $2.6B |
| Airlines (e.g., Delta) | Oil futures | Hedge jet fuel costs |
| Farmers / food companies | Commodity futures | Lock in crop prices |
| Investment funds | Interest rate swaps | Manage exposure to rate changes |
| Retail investors | Options | Bet on stock prices rising or falling |
Example: Option Simplified
Imagine you buy a call option on Apple stock:
- Apple = $150 today
- Call option strike = $160
- You pay $5 premium
If Apple goes to $180, you can buy at $160 — profit = $20 gain − $5 cost = $15 per share.
If Apple stays below $160, your option expires worthless, and you lose the $5.
So your risk is limited (the premium), but your upside can be large.
