Many new traders enter the options market expecting fast profits. The leverage is attractive — a small move in the stock can produce a large percentage gain in the option premium. That same leverage cuts both ways.
Options introduce variables that stock traders don’t face: expiration dates, Theta decay, implied volatility, liquidity, and assignment risk. Small mistakes compound quickly. A stock can move in the right direction while the option still loses money — and that surprises most beginners the first time it happens.
The good news is that most beginner mistakes follow predictable patterns. Learning to recognize them early prevents unnecessary losses and accelerates the development of real trading judgment.
This guide covers the 12 most common options trading mistakes beginners make — what causes each one, what it costs, and exactly how to avoid it.
For a solid foundation before diving in see our guide on Options Trading for Beginners.
Mistake 1: Buying Extremely Cheap Out-of-the-Money Options
This is the most common and most expensive beginner mistake — and it’s driven entirely by the psychology of low price feeling like low risk.
A $0.40 contract costs $40. A $6.00 contract costs $600. The $0.40 option feels safer. It isn’t.
Why it destroys accounts: Cheap options are cheap because they have a very low probability of expiring in the money. A $120 call on a $100 stock with 14 days to expiration requires a 20% move in two weeks just to reach the strike price. That’s not a trade — it’s a lottery ticket. Most expire worthless.
The math:
- Stock price: $100
- Call strike: $120
- Expiration: 14 days
- Premium: $0.40
- Total cost: $40
- Required move to breakeven: 20.4% in 14 days
The probability of a 20% move in 14 days on a typical large-cap stock is extremely low. Buying these options repeatedly — even at $40 each — steadily drains accounts through accumulated small losses.
The fix: Target at-the-money or slightly out-of-the-money strikes with 30-60 days to expiration. The option costs more but has a meaningfully higher probability of success. For a complete guide on selecting the right strike see our guide on How to Pick the Right Strike Price.
Mistake 2: Ignoring Theta Decay
Theta is the Greek that measures daily time decay — how much an option loses in value each day purely from the passage of time. Most beginners know options expire, but they dramatically underestimate how quickly time decay erodes option value in practice.
The impact:
- Option premium: $3.00 ($300 per contract)
- Theta: -0.12 per day
- Daily loss to time decay: $12 per contract
- After 10 days without movement: approximately $120 lost — 40% of the premium — before the stock moves a dollar
Theta accelerates as expiration approaches. An option with 45 days remaining decays slowly. The same option with 7 days remaining decays dramatically faster. The final two weeks before expiration are when Theta does its most destructive work on long options positions.
The fix: Buy options with enough time for the thesis to play out — 30-60 days minimum for most directional trades. Close positions when the trade has achieved its goal rather than holding for maximum profit. And understand that every day you hold a long option without a significant move, time is working against you. See our complete guide on What Is Theta in Options.
Mistake 3: Choosing Expirations That Are Too Short
Weekly options attract beginners because they’re cheap and move fast. Both of those characteristics are actually disadvantages for most beginner strategies.
Why short expirations hurt beginners: With 7 days remaining, the stock needs to move immediately and significantly. If the move doesn’t happen in the first few days, Theta begins accelerating and the option loses value rapidly regardless of what the stock does. There’s no time to be right — you have to be right immediately.
The math difference:
- 7-day option: Theta might be -$0.15/day. The entire premium could evaporate in a week without any adverse stock movement
- 45-day option: Theta might be -$0.05/day. You have weeks for the thesis to develop before decay becomes severe
The fix: Start with 30-60 day expirations. More time means slower decay, greater flexibility to manage the position, and more opportunity for the stock to make its move. Weekly options are appropriate for specific short-term setups — not as a default choice for beginners learning the mechanics.
Mistake 4: Buying Options Into Earnings Without Understanding IV Crush
This mistake costs beginners significant money every earnings season. The setup seems logical — a company reports earnings, the stock moves, your call profits. The reality is far more complicated.
What actually happens: Before earnings, implied volatility spikes as the market prices in uncertainty. Options become expensive across the board. The moment earnings are announced — regardless of the outcome — that uncertainty resolves and implied volatility collapses. This is called IV crush.
The devastating scenario:
- Stock at $100 before earnings
- You buy the $105 call for $5.00 ($500)
- Earnings are released — stock rises to $108 (you were right on direction)
- IV collapses 50% post-earnings
- Your call is now worth approximately $3.50 despite the stock moving in your favor
- You lose $150 on a correctly predicted direction call
The stock moved your way. You still lost money. IV crush destroyed the extrinsic value faster than the stock’s move added intrinsic value.
The fix: Understand the expected move before buying options into earnings. The expected move is the range the market is already pricing in — your option needs the stock to move beyond that range to profit after IV crush. Consider selling strategies like iron condors that benefit from IV crush rather than fighting it. See our complete guides on What Is IV Crush and What Is Implied Volatility.
Mistake 5: Trading Illiquid Options
Liquidity is one of the most overlooked variables for beginners — and one of the most expensive when ignored.
What illiquidity costs you:
- Bid: $1.20
- Ask: $1.60
- Spread: $0.40
When you buy at $1.60 and the bid is $1.20, you’re immediately down $0.40 per share — $40 per contract — the moment you enter the trade. That’s a 25% loss before the stock moves a single dollar. On a position that might only generate $100-$150 in profit if everything goes right, paying $40 in spread just to enter is a serious drag.
Signs of illiquid options:
- Open interest under 100 contracts
- Volume of 0-10 contracts per day
- Bid-ask spread more than 10% of the option price
- Large gaps between strike prices
The fix: Stick to liquid underlyings — SPY, QQQ, AAPL, NVDA, MSFT, AMZN. These have thousands of contracts of open interest at every strike and tight bid-ask spreads. Before entering any trade check that open interest is at least 500-1,000 contracts at your chosen strike. Use limit orders and target fills at or near the midpoint between bid and ask. See our guide on How to Read the Options Chain for a complete breakdown of how to evaluate liquidity.
Mistake 6: Risking Too Much Capital on One Trade
Options can produce 100-300% returns on individual trades. That potential leads many beginners to concentrate their capital — putting 20-30% of their account on a single position. This is the fastest way to turn a bad trade into an account-destroying event.
The compounding damage of oversizing:
- Account: $5,000
- Single trade risk: 20% = $1,000
- Three consecutive losses at 20%: account down to $2,900 — a 42% drawdown
Recovering from a 42% drawdown requires a 72% gain just to get back to even. Oversize a few trades, hit a normal losing streak, and you’ve created a mathematical hole that takes months or years to escape.
The fix: Risk no more than 1-5% of your account on any single options trade. On a $5,000 account that’s $50-$250 maximum risk per position. This sizing feels conservative — it is conservative, deliberately. One bad trade should never materially damage your account. See our complete guide on Managing Risk in Options Trading.
Mistake 7: Not Having an Exit Plan Before Entering
Most beginners focus entirely on entry — which option to buy, which strike, which expiration. They give almost no thought to exit — when they’ll take profit, when they’ll cut the loss, what changes their thesis.
What happens without an exit plan:
- Profitable trades get held too long waiting for more — and give back gains as Theta accelerates
- Losing trades get held too long hoping for recovery — and reach maximum loss
- Decisions get made emotionally in the middle of the trade rather than rationally before it
The fix: Before every trade define three things:
- Profit target — most experienced traders close at 50% of maximum profit on short premium trades or 100% gain on long options
- Loss limit — close if the position loses 50% of the premium paid on long options, or 2x the credit collected on short premium trades
- Time stop — close the position at 21 days to expiration regardless of profit or loss to avoid accelerating Gamma risk
Write these down before you enter. Execute them without negotiation when the trigger is hit.
Mistake 8: Holding Options Until Expiration
Related to the exit plan problem — many beginners hold options all the way to expiration hoping for a last-minute move. This is almost never the right decision.
Why holding to expiration costs money: In the final days before expiration Theta accelerates dramatically. A position that looked safe with 21 days remaining can lose half its remaining value in 48 hours if the stock stalls near the strike. The small amount of additional profit available from holding to expiration is rarely worth the accelerating risk.
For short premium positions (covered calls, credit spreads, iron condors) — holding to expiration introduces pin risk — uncertainty about whether the stock will finish just above or below your strike, creating unpredictable assignment outcomes.
The fix: Close long options positions when you’ve achieved your profit target or when significant time remains but the thesis hasn’t played out. Close short premium positions at 50% of maximum profit. Almost no situation justifies holding to expiration when the position is already profitable.
Mistake 9: Averaging Down on Losing Options Positions
When a stock position falls, averaging down — buying more at a lower price — can be a legitimate strategy. When an options position falls, averaging down is almost always a mistake.
Why options are different: Stocks don’t expire. A stock can recover its value over months or years — giving an averaging-down strategy time to work. Options expire. If the stock hasn’t moved by expiration, every dollar you added averaging down is lost alongside the original position. You’ve simply multiplied your losses.
The fix: Treat every options trade as a standalone position with a predetermined maximum loss. When that loss level is hit, close the position and move on. Adding to a losing options position to reduce average cost is one of the most reliable ways to turn a manageable loss into an account-damaging one.
Mistake 10: Using Market Orders Instead of Limit Orders
Options spreads can be wide — especially on less liquid contracts. Using a market order to buy or sell options gives away money unnecessarily every single time.
The cost:
- Bid: $1.20 / Ask: $1.80 / Mid: $1.50
- Market order buy: $1.80
- Limit order at mid: $1.50
- Cost of using market order: $30 per contract
On a trade where you’re hoping to make $100-$200, paying $30 extra just to enter is a 15-30% drag on your potential profit before the stock moves at all.
The fix: Always use limit orders. Target the midpoint between bid and ask as your starting price. If the order doesn’t fill, adjust by a few cents toward the ask (when buying) or toward the bid (when selling). Never use market orders on options — the spread will always take more than you expect.
Mistake 11: Not Understanding Assignment Risk
Beginners who sell covered calls or cash-secured puts often don’t fully understand what assignment means and when it happens — leading to surprise and panic when shares get called away or put to them.
What beginners misunderstand: Assignment is not a loss — it’s a planned outcome. If you sell a covered call at $190 and the stock rises to $200, your shares getting called away at $190 is exactly what the strategy was designed for. You keep the premium plus any gain up to the strike. The only thing you give up is the appreciation above $190.
Where it goes wrong: Selling covered calls on shares with large unrealized gains creates a taxable event if assigned — turning a paper gain into a realized one with immediate tax consequences. Selling cash-secured puts on a stock you don’t actually want to own at the strike price leads to panic when assignment happens.
The fix: Only sell covered calls at strike prices you’d genuinely be happy having your shares called away at. Only sell cash-secured puts on stocks you actually want to own at the strike price you’re selling. Assignment is a feature of these strategies — not a bug. See our complete guide on What Is Assignment in Options Trading.
Mistake 12: Overtrading
More trades does not mean more profit in options trading. It usually means more fees, more emotional decisions, and more exposure to the variance of the market.
The cost of overtrading:
- Each options trade has a bid-ask spread cost on entry and exit
- More positions means more monitoring and more emotional decisions
- Beginners who trade constantly rarely develop the patience and judgment that makes consistent options trading possible
- High-frequency options trading often generates losses even when the win rate is above 50% — fees and spreads erode the edge
The fix: Be selective. Focus on high-quality setups that match your strategy criteria rather than trading for the sake of activity. Most experienced income traders run 5-15 well-selected positions per month — not 50 trades. Quality of setup consistently beats quantity of trades.
Habits That Separate Profitable Options Traders From Beginners
The difference between traders who develop real edge and those who don’t usually comes down to a small number of consistent habits — not strategy selection.
Define exits before entry. Every trade should have a profit target, loss limit, and time stop defined before you enter. Execute those exits without negotiation.
Choose liquid underlyings. SPY, QQQ, AAPL, NVDA, MSFT. Tight spreads and easy execution make every trade more efficient.
Keep position sizes small. 1-5% of account per trade. No single trade should matter that much.
Give trades time. 30-60 day expirations for most strategies. Enough time for the thesis to develop without the brutal Theta acceleration of short-dated contracts.
Close early. 50% of maximum profit is enough. Holding for the last few dollars of potential gain is rarely worth the additional risk.
Review trades consistently. Write down what you expected versus what happened. Over time your own trade log becomes your best teacher.

Final Thoughts
Options trading is genuinely learnable — but it has a steeper learning curve than most beginners expect because of the variables that stock trading doesn’t involve. Time decay, implied volatility, liquidity, and assignment risk all require deliberate study to understand.
The 12 mistakes in this guide follow predictable patterns. Most experienced options traders made every single one of them at some point. The difference is they recognized the patterns, adjusted their process, and stopped repeating them.
The fastest path to improvement isn’t finding a better strategy — it’s eliminating the mistakes you’re already making. Smaller position sizes, liquid contracts, realistic exit plans, and enough time on your expirations will improve results more than any specific trade setup.

Frequently Asked Questions
Why do most beginners lose money trading options? The most common causes are underestimating time decay, buying cheap out-of-the-money options with low probability of success, oversizing positions, and not having exit plans before entering trades. Options introduce variables — Theta, implied volatility, liquidity — that stock trading doesn’t require understanding. Beginners who don’t study these variables make predictable and expensive mistakes.
Are weekly options bad for beginners? Generally yes. Weekly options decay extremely fast and leave very little time for a thesis to develop. A position that looks fine on Monday can be nearly worthless by Thursday if the stock hasn’t moved significantly. Beginners are better served by 30-60 day expirations which provide more time, slower decay, and more flexibility to manage positions.
Should beginners buy out-of-the-money options? Slightly out-of-the-money options are fine as part of a balanced approach. Deep out-of-the-money options — strikes 15-30% away from the current stock price — are almost always a poor choice for beginners. The probability of success is very low and the options expire worthless the vast majority of the time. The low price reflects low probability, not low risk.
How much should beginners risk per options trade? No more than 1-5% of total account value per trade. On a $5,000 account that’s $50-$250 maximum risk per position. This sizing feels conservative but it’s deliberately so — one bad trade should never be able to materially damage your account. See our complete guide on Managing Risk in Options Trading.
What is IV crush and why does it matter? IV crush is the sharp drop in implied volatility that occurs immediately after a major event — most commonly earnings — is resolved. Because implied volatility is a core component of every option’s price, this collapse reduces option values dramatically — even if the stock moves in your favor. Many beginners buy calls before earnings, the stock moves up, and they still lose money because IV crush erased the extrinsic value faster than the directional move added intrinsic value. See our complete guide on What Is IV Crush.
Is it bad to hold options until expiration? Almost always yes for long options. In the final days before expiration Theta accelerates dramatically — a position can lose significant value in 24-48 hours if the stock stalls near the strike. For short premium positions holding to expiration introduces pin risk and unpredictable assignment outcomes. Most experienced traders close positions at 50% of maximum profit rather than holding to expiration.
What is the biggest single mistake beginner options traders make? Oversizing positions. Most account blow-ups come not from choosing the wrong strategy but from risking too much on a single trade. A strategy that works 70% of the time still fails 30% of the time — if each failure costs 20% of your account, the math doesn’t work regardless of win rate. Keep each position to 1-5% of your account and no single trade can derail your progress.
How do you avoid buying illiquid options? Before entering any trade check that open interest at your chosen strike is at least 500-1,000 contracts and that the bid-ask spread is less than 10% of the option price. Stick to highly liquid underlyings — SPY, QQQ, AAPL, NVDA, MSFT — where spreads are tight and execution is reliable. Always use limit orders targeting the midpoint between bid and ask. See our guide on How to Read the Options Chain.
