Options are contracts that let you bet on where a stock will go, with less money down than buying the stock outright. They are one of the most powerful tools retail traders have access to, and also one of the fastest ways to blow up an account. This guide covers what you are actually buying, how the math works, and how to place a trade without making the mistakes every new options trader makes.
What an Option Actually Is
An option is a contract between two people. The buyer pays a premium up front for the right to buy or sell a stock at a specific price, on or before a specific date. The seller collects that premium and takes on the obligation to deliver.
That is the whole product. Every option contract, no matter how exotic it looks on a screen, is a variation on that single idea.
Two things make options different from stocks:
- They expire. Every contract has a date on it. After that date the contract is worthless.
- They cost a fraction of the stock. One call option controls 100 shares but costs far less than 100 shares would. That is leverage, and it cuts both ways.
Calls and Puts
There are only two flavors.
A call gives you the right to buy 100 shares at the strike price. You buy calls when you think the stock is going up.
A put gives you the right to sell 100 shares at the strike price. You buy puts when you think the stock is going down.
If you can remember "call up, put down" you have the beginner framework.
The Four Things You Pick
When you buy an option, you make four decisions:
- The underlying stock. Which ticker. AAPL, TSLA, SPY, whatever.
- Call or put. Your directional bet.
- Strike price. The price the contract locks in. For a call, this is the price you can buy the stock at. For a put, what you can sell at.
- Expiration date. How long you have for the trade to work.
Those four pieces together define the contract. They show up on your trading platform as a single ticker string in a format that looks like AAPL 250620C00200000, which reads as an Apple call, $200 strike, expiring June 20, 2025.
A Real Trade, Start to Finish
Here is a concrete example with real numbers.
Ford (F) is trading at $12.40. You think it rallies over the next few days. You pull up the options chain and see:
- Ford $12.50 call, expiring in 3 days
- Bid: $0.15, Ask: $0.17
You buy one contract at the ask for $0.17 per share. Because each contract controls 100 shares, your actual cost is $0.17 x 100 = $17.00, plus any broker fees.
That $17 is the premium. It is the maximum you can lose on the trade. If Ford goes to zero, you are still out $17 and nothing more. That defined-risk property is a big reason retail traders buy options in the first place.
Scenario A: Ford rips to $13. Your $12.50 call is now "in the money" by $0.50. The option is worth at least $0.50 x 100 = $50. You paid $17. You sell it and keep the difference.
Scenario B: Ford drifts to $12.35. Your strike is above the price. If you let the contract expire, it settles worthless. You lose the full $17.
Scenario C: Ford sits at $12.40. The option has no intrinsic value (strike is above the stock price), but it might still be worth $0.05 because there is time left on the clock. Every day that passes, that remaining value shrinks. This is called time decay, and it is one of the most important things to understand about options.
In the Money, Out of the Money, At the Money
Three phrases you will hear constantly:
- In the money (ITM). The option has real value if exercised right now. Call strike below the stock price, or put strike above it.
- Out of the money (OTM). The option has zero intrinsic value. Call strike above the stock, or put strike below it. Any value it has comes from the chance it becomes ITM before expiration.
- At the money (ATM). Strike is roughly equal to the current stock price.
OTM options are cheap because they probably expire worthless. ITM options are expensive because they already have real value baked in. ATM options sit in the middle and behave the most like a 50/50 bet.
Break-Even: When Do You Actually Make Money?
Break-even is the stock price at which your option trade starts being profitable, not just less negative.
For a call: break-even = strike + premium paid.
For a put: break-even = strike - premium paid.
Using our Ford example: $12.50 strike + $0.17 premium = $12.67. Ford has to close above $12.67 at expiration for you to have actually made money. Closing at $12.55 makes the call ITM but you still lose part of your premium.
This is the single biggest trap for beginners. They see the strike get hit and think they won. You need the stock to move past the strike by enough to cover what you paid for the contract.
Time Decay and Implied Volatility
Two forces push option prices around that do not exist in stock trading.
Time decay (theta). Options lose value every single day, even if the stock does not move. The closer to expiration, the faster the decay accelerates. A contract expiring next week decays faster than one expiring next month. A zero-days-to-expiration (0DTE) contract decays by the minute.
Implied volatility (IV). How much the market expects the stock to move. High IV means expensive premiums. Low IV means cheap premiums. If you buy an option after a big IV spike (earnings, news, panic) and IV drops afterward, you can lose money even when the stock moves your way. This is called an "IV crush" and it has killed more earnings trades than wrong directional calls.
The practical takeaway: check IV before you buy. If IV is unusually high, you are paying a premium for the expectation of a move, and the move has to exceed what the market already priced in.
How to Actually Place the Trade
Every broker's options chain looks slightly different, but the workflow is the same.
- Get options approval. Brokers require a short questionnaire before they let you trade options. Most approve beginners for Level 1 or 2, which covers buying calls and puts.
- Open the options chain for the ticker you want to trade.
- Pick an expiration date. For beginners, stay 2 to 4 weeks out. Shorter than that and time decay eats you alive. Longer and you are tying up capital.
- Pick a strike. Slightly out of the money (1 to 3% above the current price for a call) is a reasonable place to start. You get some leverage without paying for a lot of intrinsic value.
- Use a limit order. Never market order an option. Spreads can be ugly, especially on less liquid tickers. Set your limit between the bid and the ask, usually closer to the ask if you want a quick fill.
- Plan your exit before you enter. Know the price at which you take profits and the price at which you cut losses. Write it down.
Beginner Mistakes That Cost Real Money
Buying way out of the money. Those $0.05 lotto tickets look tempting. They almost always expire worthless. For every 9 losses you need one 10x winner just to break even, and most traders do not get the 10x winner often enough.
Holding through expiration without a plan. Time decay punishes indecision. If your thesis has not played out by the last few days, close the position.
Ignoring bid-ask spreads. If the bid is $0.50 and the ask is $0.75, you are starting 33% in the hole before the stock moves a penny. Stick to liquid names with tight spreads: SPY, QQQ, AAPL, TSLA, and similar high-volume tickers.
Sizing by dollars, not risk. "It is only $50" sounds harmless until you do it 10 times and realize you are down $500 with no trade thesis to show for it. Size by what you are willing to lose on the whole position, not what feels small today.
Chasing earnings with short-dated OTM calls. This is the classic way to donate money to the market. IV is elevated, the move needs to be outsized, and even a 5% beat can result in a loss if IV craters afterward.
Selling Options, Briefly
Everything above assumes you are the buyer. Options can also be sold, which puts you on the other side of the contract. Sellers collect the premium up front but take on the obligation.
The two most beginner-friendly ways to sell options are:
- Cash-secured puts. Sell a put on a stock you would be happy to own at the strike. You keep the premium. If the stock drops to your strike, you get assigned the shares at a discount.
- Covered calls. You already own 100 shares. Sell a call above the current price. You collect premium. If the stock rips past the strike, you give up the shares at that price, which is still a profit.
Naked option selling (selling without the underlying or cash to cover) is not for beginners. The loss potential is theoretically unlimited on naked calls. Most brokers will not approve you for it until you have traded for a while.
How RiskPicks Handles Options
The same sizing principles that apply to stock trading apply to options. Know your max loss before you enter, and size so that max loss fits your risk budget. The RiskPicks calculator will size an options trade by contracts based on your account size, risk percentage, and the premium, so you do not have to do the 100-multiplier math in your head. If you connect a broker, closed option trades get journaled automatically with full P&L, break-even, and hold time so you can review what worked and what did not.
Final Word
Options are a tool. Used with discipline, they let you take defined-risk bets with leverage that stock trading alone can not match. Used carelessly, they are the fastest account killer in retail trading.
Start small. One contract at a time, on liquid tickers, with expirations 2+ weeks out. Size your trades as if you expect to lose. Log every trade with the thesis you entered on, so you can tell over time whether your setups actually work.
The market rewards patience and discipline in every asset class. Options are no exception.
