Options give you leverage and flexibility — but they’re complex and most beginners lose money. Here’s what you need to understand before trading.
Options 101: The Basics
| Term | Definition |
|---|---|
| Call option | Right to BUY 100 shares at the strike price |
| Put option | Right to SELL 100 shares at the strike price |
| Strike price | The price you can buy/sell at |
| Premium | The price you pay for the option contract |
| Expiration | The date the option expires (worthless if out of money) |
| In the money (ITM) | Call: stock price > strike. Put: stock price < strike |
| Out of the money (OTM) | Call: stock price < strike. Put: stock price > strike |
| At the money (ATM) | Stock price ≈ strike price |
| Exercise | Using your right to buy/sell shares |
| Contract | Each contract = 100 shares |
How Calls and Puts Work
Buying a Call (Bullish Bet)
You think Stock XYZ ($100/share) will go up.
| Scenario | Stock Price at Expiration | Option Value | Profit/Loss |
|---|---|---|---|
| Bought call: $100 strike, $5 premium ($500 total) | |||
| Stock rises to $120 | $120 | $20 × 100 = $2,000 | +$1,500 (300% return) |
| Stock rises to $110 | $110 | $10 × 100 = $1,000 | +$500 (100% return) |
| Stock stays at $105 | $105 | $5 × 100 = $500 | $0 (break even) |
| Stock stays at $100 | $100 | $0 (expires worthless) | -$500 (100% loss) |
| Stock drops to $80 | $80 | $0 (expires worthless) | -$500 (100% loss) |
Max loss: Premium paid ($500). Max gain: Unlimited (stock can keep rising).
Buying a Put (Bearish Bet)
You think Stock XYZ ($100/share) will go down.
| Scenario | Stock Price at Expiration | Option Value | Profit/Loss |
|---|---|---|---|
| Bought put: $100 strike, $4 premium ($400 total) | |||
| Stock drops to $80 | $80 | $20 × 100 = $2,000 | +$1,600 (400% return) |
| Stock drops to $90 | $90 | $10 × 100 = $1,000 | +$600 (150% return) |
| Stock stays at $96 | $96 | $4 × 100 = $400 | $0 (break even) |
| Stock stays at $100 | $100 | $0 (expires worthless) | -$400 (100% loss) |
| Stock rises to $120 | $120 | $0 (expires worthless) | -$400 (100% loss) |
Max loss: Premium paid ($400). Max gain: Stock going to $0 ($10,000 - $400 = $9,600).
The Greeks: What Affects Option Prices
| Greek | What It Measures | Impact |
|---|---|---|
| Delta | How much option price changes per $1 stock move | Calls: 0 to 1. Puts: -1 to 0 |
| Theta | Time decay — how much value lost per day | Always negative for buyers (options lose value daily) |
| Gamma | Rate of change of delta | Higher near ATM and expiration |
| Vega | Sensitivity to implied volatility changes | Higher volatility = more expensive options |
| Rho | Sensitivity to interest rate changes | Usually minor |
Time Decay (Theta) — The Option Buyer’s Enemy
| Days to Expiration | Option Premium ($100 stock, $105 call) | Daily Theta |
|---|---|---|
| 90 days | $4.50 | -$0.03 |
| 60 days | $3.80 | -$0.04 |
| 30 days | $2.50 | -$0.06 |
| 14 days | $1.50 | -$0.08 |
| 7 days | $0.80 | -$0.10 |
| 1 day | $0.10 | -$0.10 |
| Expiration | $0.00 (if OTM) | — |
Options lose value every single day. The closer to expiration, the faster they decay.
Basic Option Strategies (Beginner-Friendly)
1. Covered Call (Conservative Income)
| Item | Details |
|---|---|
| Setup | Own 100 shares of stock + sell 1 call option |
| Goal | Earn premium income on stock you already own |
| Risk | Stock could drop (same as owning stock); upside capped |
| Example | Own 100 shares XYZ at $100, sell $110 call for $3 |
| Max profit | $13/share ($10 appreciation + $3 premium) |
| Max loss | $97/share (stock goes to $0, but you keep $3 premium) |
| Ideal for | Income on existing holdings, slightly bullish outlook |
2. Cash-Secured Put (Buy Stock at a Discount)
| Item | Details |
|---|---|
| Setup | Sell 1 put option with cash to cover purchase |
| Goal | Collect premium OR buy stock at a lower price |
| Risk | Must buy 100 shares if stock drops below strike |
| Example | Sell XYZ $95 put for $3, hold $9,500 cash |
| If stock stays above $95 | Keep $300 premium, free money |
| If stock drops to $90 | Buy 100 shares at $95, effective cost $92 ($95 - $3 premium) |
| Ideal for | Wanting to buy a stock at a lower price |
3. Protective Put (Insurance)
| Item | Details |
|---|---|
| Setup | Own 100 shares + buy 1 put option |
| Goal | Protect against downside while keeping upside |
| Risk | Cost of premium if stock doesn’t drop |
| Example | Own 100 shares at $100, buy $95 put for $3 |
| Stock drops to $70 | Sell at $95 (loss limited to $8/share) |
| Stock rises to $120 | Great — profit is $20/share minus $3 premium = $17 |
| Ideal for | Protecting concentrated positions |
