What are stock options?

Options are contracts that give you the right (but not obligation) to buy or sell a stock at a specific price (strike price) before a specific date (expiration). A call option bets the stock will go up. A put option bets the stock will go down. Each contract controls 100 shares. You pay a premium for this right.

Are options risky for beginners?

Yes. Options can lose 100% of your investment very quickly. According to studies, about 70-90% of options expire worthless. Options are complex instruments involving time decay, implied volatility, and leverage. Most beginners should master stock and index fund investing before considering options. If you do trade options, start with covered calls or cash-secured puts — the simplest strategies.

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

Options vs Stocks: Risk Comparison

Factor	Buying Stocks	Buying Options
Maximum loss	Stock goes to $0 (rare for quality companies)	100% of premium (common)
Typical holding period	Years	Days to months
Time works for/against you	Neutral	Against you (time decay)
Leverage	1x (no leverage)	10-100x+ leverage
Income	Dividends	Premium (if selling)
Simplicity	Simple	Complex
Success rate (most studies)	70-80% over 10+ years	10-30% of options buyers profit

Common Mistakes

Mistake	Why It’s Costly
Buying far OTM options	Very cheap but almost always expire worthless
Trading weekly expirations	Extreme time decay, near-gambling
Not understanding assignment	You may be forced to buy/sell shares
Ignoring implied volatility	High IV = expensive premiums (after earnings, etc.)
Overleveraging	Small move against you = large % loss
Holding through expiration	Time decay accelerates near expiration
Trading on tips/memes	Following social media trades without understanding
No exit plan	Not knowing when to take profit or cut losses
