Less jargon.
More “now I get it.”

Move one input. Watch the effect. Start with the five Greeks that describe how an option responds to change.

01 / PRICE SENSITIVITY

When the stock moves,
the option moves too.

Delta estimates the change in an option’s price for a $1 rise in the underlying, with other inputs held steady. Calls generally have positive delta; puts generally have negative delta.

Try moving the stock price. Notice that the option’s price does not move dollar for dollar.

What this example assumes

A hypothetical European-style option using the Black–Scholes model, a $100 strike and no dividends. Prices are per share. Theta is per calendar day; vega and rho are per one percentage point. We vary one input at a time. These are theoretical estimates, not market quotes, profit forecasts or trade recommendations. The model does not account for early exercise, fees, spreads or changing market conditions.

Options, in plain English

What are calls and puts?

A call gives its holder the right to buy the underlying at the strike price. A put gives its holder the right to sell. Each contract has an expiry and an exercise style. The holder pays a premium; the seller takes on an obligation if assigned. Contract specifications determine the deliverable and multiplier.

What should I check before a trade?

Start with the underlying, strike, expiry, exercise style and contract multiplier. Understand the premium, bid–ask spread and liquidity. Examine scenarios where the price moves against you, time passes or volatility changes. Know how exercise and assignment work, and what your broker requires.

What can I lose?

A buyer can lose the entire premium paid. Some short-option positions can lose more than the credit received, and an uncovered short call can have unlimited loss. Exercise or assignment can create stock positions and additional obligations. A calculator is a model, not a guarantee.
