Options in 60 Seconds
An option is a contract giving you the right — but not the obligation — to buy or sell 100 shares of stock at a specific price (strike price) before a set date (expiration). You pay a premium for this right.
Call option
Right to BUY 100 shares at the strike price. Profitable when the stock rises above strike + premium.
Put option
Right to SELL 100 shares at the strike price. Profitable when the stock falls below strike − premium.
Premium
The price you pay per share to own the option contract. Max loss for buyers; income for sellers.
Expiration
The date after which the option ceases to exist. Time decay (Theta) accelerates as this date approaches.

Options Greeks
Options Greeks Explained
Delta, Gamma, Theta, Vega — the four Greeks every options trader must understand. Know what moves your position and why.
Plain-English Explanation
If a call has a Delta of 0.50, the option price rises ~$0.50 for every $1 the stock goes up. An at-the-money option has ~0.50 Delta. Deep ITM options approach ±1.00; deep OTM options approach 0.
Calls
Always positive (0 → +1). Rises as stock rises.
Puts
Always negative (-1 → 0). Becomes more negative as stock falls.
Trader Tip
Use Delta as a rough probability estimate — a 0.30 Delta call has ~30% chance of expiring in the money.
Common Scenarios
Deep in-the-money
±0.90–1.00
At-the-money
±0.50
Out-of-the-money
±0.10–0.20
What about Rho?
Rho measures sensitivity to interest rate changes. For most short-dated equity options, Rho is negligible. It matters most for long-dated LEAPS (1+ year) and during major Fed rate decisions.
Put it into practice
Use the Options P&L Calculator above to see how Delta and Theta affect your trade in real time.
Delta
$1 stock move → option price change
Gamma
$1 stock move → Delta change
Theta
1 day passes → option value lost
Vega
1% IV change → option price change

Implied Volatility
Implied Volatility Explained
IV is the market's forward-looking fear gauge — and the key driver behind Vega. Understand IV Rank and IV Percentile to know if options are cheap or expensive right now.
What Is Implied Volatility (IV)?
The market's consensus forecast of future price swings
Implied Volatility is derived by reverse-engineering an option's market price through the Black-Scholes model. Rather than predicting direction, it measures how much the market expects a stock to move — up or down — over the next year, expressed as an annualized percentage.
If a stock has an IV of 30%, the market is pricing in a roughly ±30% move over the next 12 months. Divide by √52 to get the weekly expected move (~4.2%), or √252 for a single-day expected move (~1.9%).
IV %
Annual expected move
IV ÷ √52
Weekly expected move
IV ÷ √252
Daily expected move
IV vs Historical Volatility (HV)
Forward-looking. What the market expects to happen. Derived from option prices.
Backward-looking. How much the stock actually moved in the past. Calculated from price history.
The Edge
When IV > HV, options are priced rich — sellers have an edge. When IV < HV, options are cheap — buyers have an edge.
IV Rank (IVR)
Where is current IV relative to its 52-week range?
Formula
IVR = (Current IV − 52w Low) ÷ (52w High − 52w Low) × 100
IVR compares today's IV to the 52-week high and low. An IVR of 80 means IV is at the 80th point of its annual range — near the top. An IVR of 10 means IV is near its 52-week low.
Limitation: A single outlier spike can compress all readings for a year. IVR says where in the range, not how often IV has been this level.
IV Percentile (IVP)
How often has IV been lower than it is today?
Formula
IVP = (Days IV was below current IV) ÷ (Total days in lookback) × 100
IVP counts how many of the past 252 trading days had IV lower than today. An IVP of 85 means IV has been lower on 85% of all days in the past year — today is quite elevated in terms of frequency, not just position in range.
IVR vs IVP — which to use?
Use IVR when you want to know where in the range today's IV sits.
Use IVP when you want to know how unusual today's IV level is historically.
Best practice: look at both. High IVR + High IVP = strong sell signal.
Advantage over IVR: A single spike doesn't distort IVP — it's based on frequency, making it more robust for identifying premium-selling opportunities.

Calm market — premiums are cheap
Average conditions — balanced risk/reward
Elevated fear — premiums are expensive
Panic / crisis — options are very expensive
Beware: IV Crush
The most common way options buyers lose money
Before earnings, IV spikes as traders speculate on the outcome. The moment results are announced, uncertainty collapses — and so does IV. This can wipe out 30–50% of an option's value even if the stock moves in the right direction.
IV & Vega are inseparable
Vega measures how much your option price changes per 1% IV move. Knowing the current IV level tells you whether buying Vega (going long options) or selling Vega (shorting premium) is the higher-probability play.

The Golden Rule of Options Volatility
Buy options when IV is low (IVR < 30) — cheap Vega, room to expand. Sell options when IV is high (IVR > 60) — collect inflated premium before it contracts.

Options Trading FAQs
Answers to the most common questions from new and intermediate options traders.
Options trading involves buying or selling contracts that give you the right — but not the obligation — to buy (call) or sell (put) 100 shares of stock at a fixed price before a set expiration date. You pay a premium for this right. Buyers profit from big moves; sellers profit from time passing and volatility declining.
