What Are Options? (Insurance Policy Analogy)
Car Insurance Analogy: Buying an option is like buying insurance on someone else’s car (the stock) that you don’t own yet. You pay a small premium upfront ($300 for insurance). If the car gets totaled (stock crashes), your insurance pays out big ($10,000+). But if the car is fine (stock doesn’t move), you just lose the $300 premium—no refund.
The Basics:
An option is a contract that gives you the RIGHT (not obligation) to buy or sell 100 shares of a stock at a specific price (strike) by a specific date (expiration).
Two types:
- Call Option: Right to BUY stock (you want stock to go UP)
- Put Option: Right to SELL stock (you want stock to go DOWN)
Key Terms:
1. Strike Price: The price at which you can buy (call) or sell (put) the stock.
Example: AAPL $180 call = Right to buy Apple at $180/share.
2. Expiration Date: Deadline. After this date, the option expires worthless if not exercised.
Example: Apple $180 call expiring Jan 19, 2024.
3. Premium: The price YOU pay to buy the option contract (per share × 100).
Example: Premium = $3/share → Total cost = $3 × 100 = $300.
4. In-the-Money (ITM): Your option has value if exercised today.
- Call ITM: Stock price > Strike price (AAPL at $190, strike $180 = ITM)
- Put ITM: Stock price < Strike price (AAPL at $170, strike $180 = ITM)
5. Out-of-the-Money (OTM): Your option has NO value if exercised today.
- Call OTM: Stock price < Strike price (AAPL at $175, strike $180 = OTM)
- Put OTM: Stock price > Strike price (AAPL at $185, strike $180 = OTM)
6. At-the-Money (ATM): Stock price = Strike price (AAPL at $180, strike $180 = ATM)
Real Example - Call Option:
Date: December 1, 2023 Stock: Apple (AAPL) trading at $180
You think Apple will rally to $200 by January.
Option contract:
- Type: Call (betting on price increase)
- Strike: $185
- Expiration: January 19, 2024 (7 weeks away)
- Premium: $4/share → Total cost = $400
Scenario 1 - You’re Right (Apple rallies to $200): January 15, 2024: Apple hits $200. Your call option ($185 strike) is now worth $15/share.
- Option value: $15 × 100 = $1,500
- Your cost: $400
- Profit: $1,100 (+275%)
If you had bought 100 shares outright:
- Cost: $180 × 100 = $18,000
- Value at $200: $20,000
- Profit: $2,000 (+11%)
Options gave you 25x leverage with $400 vs $18,000.
Scenario 2 - You’re Wrong (Apple drops to $170): January 19, 2024: Apple is at $170 (below $185 strike). Your call is worthless. No one wants the right to buy at $185 when market price is $170.
- Option value: $0
- Your cost: $400
- Loss: $400 (-100%)
If you had bought shares:
- Cost: $180 × 100 = $18,000
- Value at $170: $17,000
- Loss: $1,000 (-5.6%)
Options risk: Lose 100% of premium. Shares risk: Lose only 5.6%, and you still own shares (can recover).
Why Options Exist:
Options serve three purposes:
- Leverage (Speculation): Control $20k worth of stock with $400.
- Hedging (Insurance): Protect existing stock positions from crashes.
- Income Generation: Sell options to collect premium (advanced).
Beginners should focus on #1: Buying calls and puts for leverage.
Trading Tip: Options are NOT ‘get rich quick.’ They’re ‘high risk, high reward.’ 80% of options expire worthless. Only trade with money you can afford to lose 100%.
Calls vs. Puts (Explained Simply)
Sports Betting Analogy: Imagine you’re betting on a football game.
- Call Option = Betting the team will WIN (score goes UP)
- Put Option = Betting the team will LOSE (score goes DOWN)
CALL OPTIONS (Bullish - Stock Goes UP)
When to Buy a Call: You believe a stock will rise significantly in the next 30-90 days.
Example - Tesla Earnings Play: Date: October 10, 2023 Stock: Tesla (TSLA) at $250
Earnings report coming October 18. You think they’ll beat expectations and stock will jump to $280.
Trade:
- Buy: TSLA $260 Call expiring October 20 (10 days)
- Premium: $5/share → Cost = $500
Outcome (Tesla beats earnings): October 19: TSLA jumps to $285 after earnings.
- Your call ($260 strike) is worth $25/share ($285 - $260)
- Option value: $25 × 100 = $2,500
- Profit: $2,000 (+400%)
If you had bought shares:
- Bought 20 shares at $250 = $5,000
- Sold at $285 = $5,700
- Profit: $700 (+14%)
Call option gave you 28x more profit percentage with 10x less capital.
Risk: If Tesla missed earnings and dropped to $240, your $500 call = $0. Shares would only be down $200 (-4%) and recoverable.
PUT OPTIONS (Bearish - Stock Goes DOWN)
When to Buy a Put: You believe a stock will crash in the next 30-90 days.
Example - Bank Crisis Play: Date: March 8, 2023 Stock: First Republic Bank (FRC) at $115
Banking crisis news. You think FRC will collapse to $80.
Trade:
- Buy: FRC $110 Put expiring March 31 (3 weeks)
- Premium: $8/share → Cost = $800
Outcome (Bank collapses): March 13: FRC crashes to $30 (regional bank panic).
- Your put ($110 strike) is worth $80/share ($110 - $30)
- Option value: $80 × 100 = $8,000
- Profit: $7,200 (+900%)
Shares would require short selling (borrowing shares to sell), which most beginners can’t do. Puts give you downside profit without shorting.
If you had shorted 100 shares:
- Borrowed and sold at $115 = $11,500 received
- Bought back at $30 = $3,000 paid
- Profit: $8,500 (+74%)
But shorting requires margin account, borrow fees, and unlimited loss risk (if stock goes up, you lose infinite). Puts cap your loss at $800.
Call vs. Put Summary:
| Type | Bet | Max Loss | Max Gain | Best For |
|---|---|---|---|---|
| Call | Stock UP | Premium paid | Unlimited | Bullish plays, earnings beats |
| Put | Stock DOWN | Premium paid | Large (stock can’t go below $0) | Crash plays, hedging |
Which to Use?
Buy Calls when:
- Earnings are coming and you expect a beat
- Stock breaks out above resistance
- Major product launch expected to succeed
- FDA approval anticipated (biotech)
Buy Puts when:
- Earnings coming and you expect a miss
- Stock looks overvalued (P/E > 50, hype driven)
- Bad news expected (regulatory issues, lawsuits)
- Market crash anticipated (hedge your portfolio)
Common Beginner Mistake:
Buying both a call AND a put on the same stock (called a ‘straddle’), hoping ‘it moves big in either direction.’
Why this fails: You pay double premium ($500 + $500 = $1,000). Stock needs to move >20% just to break even. 90% of the time, stocks don’t move that much, and you lose both premiums.
Trading Tip: Stick to ONE direction (call OR put) per trade. If you’re unsure of direction, don’t trade options—trade shares or wait.
The Greeks: Understanding Option Pricing
Car Dashboard Gauges Analogy: The Greeks are like gauges on your car dashboard. Speed (Delta), fuel efficiency (Theta), temperature (Gamma), road conditions (Vega). You don’t need to be a mechanic, but you should know what the gauges mean.
Why Greeks Matter:
Option prices change based on 4 factors:
- Stock price movement (Delta)
- Time passing (Theta)
- Volatility changes (Vega)
- Acceleration of price movement (Gamma)
Understanding these helps you avoid beginner mistakes like buying an option that loses money even when you’re right about direction.
DELTA: Price Sensitivity
What it is: How much your option price changes when the stock moves $1.
- Delta = 0.50 → Stock up $1, option up $0.50
- Delta = 0.80 → Stock up $1, option up $0.80
Range:
- Calls: 0 to 1.0 (deep ITM calls approach 1.0)
- Puts: 0 to -1.0 (deep ITM puts approach -1.0)
Example: You own NVDA $500 call, stock at $520 (ITM). Delta = 0.70
NVDA jumps from $520 to $530 (+$10). Your option gains: $10 × 0.70 = $7/share → $700 total.
How to Use:
- Want max leverage? Buy OTM options (Delta 0.20-0.40). Cheap but risky.
- Want consistency? Buy ITM options (Delta 0.70-0.90). Expensive but safer.
Trading Tip: Beginners should aim for Delta 0.40-0.60. Sweet spot between leverage and probability.
THETA: Time Decay (The Silent Killer)
What it is: How much your option loses in value each day as expiration approaches.
- Theta = -0.05 → Lose $5/day ($0.05 × 100 shares)
- Theta = -0.20 → Lose $20/day
The Problem: Even if the stock doesn’t move, you’re losing money EVERY DAY.
Example: You buy AAPL $180 call for $5/share ($500 total). Theta = -0.10 ($10/day decay).
Day 1: Option worth $500 Day 7 (stock unchanged at $180): Option worth $430 ($500 - $70) Day 30: Option worth $200 (if stock still at $180)
You were right about direction (stock didn’t drop), but you LOST $300 because time passed.
Theta Acceleration: Time decay is NOT linear. It accelerates as expiration nears.
- 90 days out: Theta = -0.03 ($3/day)
- 30 days out: Theta = -0.10 ($10/day)
- 7 days out: Theta = -0.30 ($30/day)
- 1 day out: Theta = -1.00 ($100/day)
This is why options lose 50%+ of value in the final 2 weeks even if stock is flat.
How to Fight Theta:
- Buy options 60-90 days out (Theta is slow)
- Close winners early (Don’t hold to expiration)
- Set profit targets (50-100% gain, then sell)
- Avoid buying options with <30 days (Theta too fast)
Real Disaster Example: Trader buys TSLA $250 call expiring in 5 days for $3/share ($300). Theta = -0.60 ($60/day).
TSLA stays flat at $245 for 5 days. Day 5: Option expires worthless. $300 → $0.
If they had bought the same call with 60 days, they’d have lost $60 (10%) instead of 100%.
Trading Tip: Theta is your enemy when buying options. Fight it by:
- Buying further-dated options (60-90 DTE)
- Taking profits quickly (don’t get greedy)
- Never holding through final expiration week
VEGA: Volatility Sensitivity
What it is: How much your option price changes when volatility (fear/uncertainty) increases or decreases.
- Vega = 0.15 → Volatility up 1%, option up $0.15/share
Why it matters: Earnings, news events, market crashes spike volatility → options get MORE expensive. Calm markets → volatility drops → options get CHEAPER.
Example - Earnings Volatility: Apple announces earnings in 3 days.
Before earnings:
- Implied Volatility (IV) = 30%
- AAPL $180 call = $5/share
Day before earnings (fear spikes):
- IV jumps to 50%
- Same call = $7/share (despite stock unchanged)
Vega made your option +40% more valuable just from fear.
After earnings (fear gone):
- IV drops back to 25%
- Call = $4/share (even if stock went up slightly)
The ‘IV Crush’: After earnings, volatility collapses. This is called IV crush. Even if stock moves your direction, your option can LOSE money.
Example - Snap Earnings April 2023: SNAP trading at $10. You buy $11 call for $1 (IV = 120%).
Earnings beat. SNAP jumps to $11.50. Your call should be worth $0.50 intrinsic value + premium.
But IV crushes from 120% to 40%. Call now worth $0.30. You LOST $0.70 even though you were right.
How to Avoid IV Crush:
- Don’t buy options right before earnings (IV is inflated)
- Buy options 2-4 weeks BEFORE earnings (IV still low)
- Sell BEFORE earnings (capture IV spike without crush)
- Or play earnings with spreads (advanced)
GAMMA: Acceleration (Advanced)
What it is: How fast Delta changes as stock moves.
High Gamma = Delta changes fast (more explosive gains/losses). Low Gamma = Delta changes slow (more predictable).
When to care: ATM options (strike = stock price) have highest Gamma. OTM/ITM options have low Gamma.
Beginner takeaway: Don’t worry about Gamma until you master Delta, Theta, and Vega.
Greeks Cheat Sheet:
| Greek | Measures | You Want | You Avoid |
|---|---|---|---|
| Delta | Price sensitivity | 0.40-0.60 (balanced) | <0.20 (lottery ticket) |
| Theta | Time decay | Low (-0.05) | High (-0.30+) |
| Vega | Volatility impact | High (before events) | High (after events) |
| Gamma | Delta acceleration | Don’t worry yet | Don’t worry yet |
Trading Tip: Focus on Delta and Theta first. Once you’re profitable, learn Vega. Ignore Gamma for now.
Common Options Mistakes (And How to Avoid Them)
80% of Options Expire Worthless. Here’s why, and how to join the 20% who profit.
MISTAKE #1: Buying Options That Are Too Far Out-of-the-Money (OTM)
The Trap: Beginner sees: ‘Tesla $500 call for $0.50! If TSLA goes to $550, I’ll make $50/share → $5,000 profit!’
Reality: TSLA is at $250. For that call to be profitable, Tesla needs to DOUBLE (+100%) in 30 days. Probability: <1%.
Real Example: GameStop (GME) mania January 2021. GME at $40.
Retail traders bought $800 calls for $0.10 ($10 total). GME did squeeze to $483. But even at $483, the $800 call was still worthless.
Fix: Buy options with strike prices within 5-10% of current stock price.
- Stock at $100? Buy $105 call (achievable).
- Avoid $150 calls (requires +50% move).
MISTAKE #2: Buying Options Expiring in <30 Days
The Trap: Cheaper premium = less risk, right? WRONG.
Short-dated options have:
- Massive Theta decay (-$20-50/day in final week)
- Low probability of success (not enough time)
- One red day can wipe you out
Real Example: Trader buys NVDA $500 call expiring in 7 days for $2/share ($200). NVDA at $490.
Day 1-4: NVDA flat at $490. Option loses $0.60/day = $240 total loss. Day 5: NVDA jumps to $505. Option now worth $5/share ($500).
Net: $300 gain.
BUT if trader had bought 60-day expiration:
- Same move, but only lost $60 to Theta instead of $240.
- Net: $580 gain.
Short-dated options COST more in the long run due to Theta.
Fix: Buy options with 60-90 days to expiration (DTE).
- Gives your thesis time to play out
- Theta decay is slow ($3-5/day vs $30-50/day)
- Allows you to hold through short-term volatility
MISTAKE #3: Holding Options Through Expiration Week
The Trap: ‘My option expires Friday. I’ll hold until then to maximize gains!’
No. The final week is where Theta murders you.
Real Example: Monday: AAPL $180 call (expiring Friday) worth $3/share. Stock at $182. Wednesday: Stock still $182. Option worth $2.30 (lost $0.70 to Theta). Friday: Stock at $182. Option expires worth $2 (intrinsic value only).
You lost $1/share ($100) just by holding 5 days.
Fix: Close options 7-10 days before expiration.
- Sell when you hit 50-100% profit
- Don’t get greedy trying to squeeze last dollar
- Theta in final week destroys 50%+ of value
MISTAKE #4: Buying Options Right Before Earnings
The Trap: ‘Earnings tomorrow! Stock could jump 10%! I’ll buy a call!’
IV (Implied Volatility) SPIKES before earnings. You’re paying 2-3x normal premium.
After earnings, IV collapses (IV crush). Even if stock moves your way, you can lose.
Real Example: Meta (Facebook) Q3 2023 earnings.
Before earnings (day before):
- META at $300
- $310 call = $8/share (IV = 80%)
Earnings beat. META jumps to $320.
After earnings:
- IV drops to 30%
- $310 call = $11/share
Profit: $3/share ($300).
But if you bought 2 weeks earlier (before IV spike):
- Same $310 call = $4/share (IV = 35%)
- After earnings: $11/share
- Profit: $7/share ($700)
IV inflation cost you $400 in profits.
Fix: Buy options 2-4 weeks BEFORE earnings (IV still low). Sell 1-2 days BEFORE earnings (capture IV spike). Or avoid earnings entirely.
MISTAKE #5: No Stop Loss
The Trap: ‘Options are already risky. Why set a stop?’
Because turning a -50% loss into -100% is stupid.
Rule: Set stop loss at 50% of premium paid.
Bought call for $5/share ($500)? Sell if it hits $2.50 ($250).
This caps your loss at $250 instead of $500.
Example: You buy 3 options (different stocks) for $500 each ($1,500 total).
No stop loss:
- Trade 1: -100% ($500 loss)
- Trade 2: -100% ($500 loss)
- Trade 3: +200% ($1,000 profit)
- Net: -$0 (break even after 3 trades, 33% win rate)
With 50% stop:
- Trade 1: -50% ($250 loss)
- Trade 2: -50% ($250 loss)
- Trade 3: +200% ($1,000 profit)
- Net: +$500 (profit, same 33% win rate)
Stop losses turn break-even into profit.
MISTAKE #6: Over-Leveraging (Buying Too Many Contracts)
The Trap: ‘Options are cheap! I can buy 20 contracts for $2,000!’
Then stock moves against you. All 20 expire worthless. $2,000 → $0.
Fix: Risk only 1-2% of account per options trade.
$10k account? Max $100-200 per trade. $50k account? Max $500-1,000 per trade.
Yes, this means buying 1-2 contracts instead of 20. But you’ll survive losing streaks.
Real Example: Trader with $10k account buys $5k in Tesla calls (50% of account). TSLA drops. Calls expire worthless. Account now $5k. Needs +100% gain to recover.
If they risked $200: Loss = $200. Account = $9,800. Needs +2% to recover.
Options Success Formula:
✅ Buy options 60-90 days out (fight Theta) ✅ Buy strikes within 5-10% of stock price (realistic) ✅ Avoid earnings week (IV crush) ✅ Set 50% stop loss (cap losses) ✅ Take profits at 50-100% (don’t get greedy) ✅ Close 7-10 days before expiration (avoid final Theta) ✅ Risk max 2% per trade (survive losses)
Trading Tip: Most options traders lose money not because they’re wrong about direction, but because they ignored Theta, IV, and risk management. Master the Greeks before you master stock picking.
Frequently asked questions
- How much money do I need to start trading options?
- Minimum $2,000-5,000, but realistically $10,000+ for proper risk management. Here's why: Most brokers require $2,000 minimum for options approval (margin account requirement). But with $2,000, if you risk 2% per trade ($40), you can only buy 1-2 option contracts. One bad trade and you're down 2%. Five losses in a row = -10%. With $10,000, you can risk $100-200 per trade (1-2%), buy 2-4 contracts, diversify across multiple positions, and survive 10+ losing trades before significant damage. Reality check: 80% of options traders lose money in their first year. If you only have $2,000, that's your 'tuition' to learn. Budget for it. Better: Start with $10k, risk 1% ($100) per trade, and treat options as 10-20% of your portfolio. Use the other 80-90% in shares/ETFs for stability. If you don't have $10k: Paper trade (fake money) for 6 months first. Learn without losing real money. Once consistently profitable in paper account, then deposit $5k-10k.
- Should I buy options or sell options?
- BEGINNERS: Buy options only. NEVER sell until you have 1+ years experience. Here's why: **Buying options:** Max loss = premium paid ($500). Max gain = unlimited (calls) or large (puts). You know your risk upfront. **Selling options (writing):** Max gain = premium collected ($500). Max loss = UNLIMITED (if you sell naked calls) or very large (if you sell puts). You collect $500 but risk $50,000+. Selling options is what professionals and institutions do because they have: (1) Sophisticated hedging strategies, (2) Millions in capital to absorb losses, (3) Teams of analysts managing risk. You don't have this. Example disaster: Trader sells 10 TSLA $200 puts, collects $2,000 premium. 'Easy money!' Tesla crashes from $250 to $100 (it happened in 2022). Now forced to buy 1,000 shares at $200 when market price is $100. Loss: $100,000. Premium collected: $2,000. Net: -$98,000 wipeout. This is why r/wallstreetbets is full of -$200k loss porn from selling options. The 'advanced strategy' of selling covered calls or cash-secured puts is fine AFTER you master buying. But start simple: buy calls and puts. Learn to profit consistently. THEN explore selling. Don't skip steps.
- What's the best time frame for options - weekly, monthly, or LEAPS?
- **For beginners: 60-90 days (2-3 months).** Here's the breakdown: **Weekly options (7 days or less):** 95% lose money. Theta decay is -$20-50/day. One bad day and you're wiped out. Only for day traders with experience. AVOID. **Monthly options (30-60 days):** Better, but still risky. Theta = -$5-15/day. Good for experienced traders with high conviction. Beginners: Use cautiously. **2-3 Month options (60-90 DTE - Days To Expiration):** IDEAL for beginners. Theta = -$2-5/day (manageable). Gives your thesis time to play out. Allows you to hold through short-term noise. Close at 50-100% profit or 7-10 days before expiration. **LEAPS (1-2 years):** Long-term options. Expensive ($2,000-5,000 per contract). Low Theta, but ties up capital. Good for long-term bullish plays (e.g., 'I think NVDA will 3x in 2 years'). Advanced strategy. Why 60-90 days is the sweet spot: (1) Theta is slow enough to fight. (2) Price is affordable ($300-800 vs $3,000 for LEAPS). (3) Time for stock to move your direction. (4) You can trade multiple times per year (vs LEAPS locks capital for 1-2 years). Example: You think AAPL will go from $180 to $200. Weekly $185 call: $50, expires in 7 days. Theta = -$7/day. AAPL needs to hit $200 THIS WEEK. Stressful. 60-day $185 call: $400, expires in 60 days. Theta = -$3/day. AAPL has 2 months to hit $200. Realistic. Recommendation: Buy 60-90 day options, close winners at 50-100% profit. Rinse and repeat. Don't get fancy with weeklies or LEAPS until you're profitable.
- Can I day trade options with a small account (<$25k)?
- Yes, BUT it's extremely difficult and has restrictions. Here's the reality: **Pattern Day Trader (PDT) Rule (US only):** If you have <$25k in your account, you're limited to 3 'day trades' per 5-day period. Day trade = Buy and sell same security (including options) on same day. After 3 day trades in 5 days, you're flagged. Next day trade = account frozen for 90 days. **Ways around PDT (all have downsides):** (1) Open multiple broker accounts: 3 trades at Robinhood, 3 at Webull, 3 at TD. Messy, hard to track. (2) Swing trade instead: Buy options, hold overnight, sell next day. Not 'day trading' under PDT rules. But adds overnight risk (news, gap downs). (3) Trade cash account (not margin): No PDT rule, but you must wait 2 days for funds to settle after each trade. Can only use 1/3 of capital per day. (4) Move to non-US broker: PDT is US-only. Interactive Brokers (Europe) has no PDT. But adds complexity. (5) Save up $25k: Best solution. **Why day trading options with <$25k is hard even without PDT:** (1) Options are volatile. One bad trade = -$500 (10% of $5k account). (2) Theta decay. If you hold option for 6 hours, you lose $10-30 to time decay even if stock is flat. (3) Bid-ask spreads. Options have wide spreads. Buying at $3.00, selling at $2.80 = instant -7% loss. (4) Commissions. $0.65/contract fees add up. 10 trades/day = $13/day = $250/month. (5) Emotional toll. Watching options swing ±50% intraday is stressful. Leads to revenge trading, over-trading. **Real example:** Trader with $5k tries day trading options. Day 1: +$200. Day 2: -$400. Day 3: +$100. Day 4 (4th day trade): Account flagged. Can't trade for 90 days. Stuck in losing position overnight. Gap down next morning: -$300 more. Account now $4,600. **Recommendation:** If you have <$25k, do NOT day trade options. Instead: (1) Swing trade: Buy options with 60-90 DTE, hold 2-5 days, close at profit. (2) Position trade: 1-2 trades/month, high conviction plays. (3) Save to $25k, THEN day trade if you still want to.
- Do I need to exercise my option or can I just sell it?
- 99% of the time: SELL the option. Don't exercise. Here's why: **Exercising = Converting option into shares.** If you own AAPL $180 call and stock is at $200: Exercising means: Pay $180 × 100 = $18,000 to buy 100 shares at $180. You now own 100 shares worth $200 × 100 = $20,000. Profit: $2,000 (minus $400 option cost) = $1,600. **Selling the option:** That same call is worth $20/share (intrinsic value $20 + time value $2) = $22 × 100 = $2,200. Sell it for $2,200. Cost was $400. Profit: $1,800. **Selling nets you $200 MORE because you capture the remaining time value ($2/share).** When you exercise, you THROW AWAY time value. **When to exercise (rare cases):** (1) **You actually WANT the shares:** Long-term investor, want to hold AAPL for years. Then exercising makes sense. (2) **Dividend capture:** Stock pays $2/share dividend tomorrow. Exercise today, collect dividend. (3) **Deep ITM with no time value left:** Option expiring today, stock at $210, strike $180. Time value = $0. Exercising vs selling = same result. **99% of traders:** Just sell the option and take the cash. It's simpler, faster, and nets more profit. **Real example mistake:** Newbie buys TSLA $300 call for $10 ($1,000). TSLA hits $400. Call worth $105/share ($10,500). Profit = $9,500. Trader 'exercises' because they think that's what you're 'supposed to do.' Now they own 100 shares at $300 = $30,000 tied up. They don't have $30,000 in account. Broker margin calls them, forces sale, charges interest. Mess. Should've just sold the call for $10,500 profit. Clean, simple. **Broker tip:** Most brokers (Robinhood, Webull, TD) auto-sell your ITM options on expiration day if you don't have capital to exercise. So even if you forget, you won't accidentally exercise. But don't rely on this—always close your positions manually.
