A field guide for patient decision-makers

Options
Farm

Options are not shortcuts. They are contracts with clocks attached. Learn the mechanics, name the risks, and cultivate a process before putting capital to work.

01 — Read the contract

Start with what an option actually is.

An option gives its buyer a right—not an obligation—to buy or sell an underlying asset at a defined price before or at expiration. The seller accepts the corresponding obligation.

Every contract has an underlying asset, strike price, expiration date, premium, and exercise style. Those details determine what can happen and when. Always read the full contract specification before evaluating a trade.

C

Call option

The buyer receives the right to buy at the strike price. A call may gain value when the underlying rises, but price, time, and volatility all matter.

P

Put option

The buyer receives the right to sell at the strike price. Puts can express a bearish view or help define downside exposure.

Δ

Greeks

Delta, gamma, theta, and vega describe sensitivities—not guarantees. They change as price, time, and implied volatility change.

02 — Protect the soil

Risk has more than one dimension.

A correct market direction can still produce a losing options position. Price paid, time remaining, volatility, liquidity, and position size shape the outcome.

  1. 01
    Limited life.
    Long options can expire worthless, resulting in the complete loss of the premium paid.
  2. 02
    Leverage.
    Small underlying moves can create large percentage changes. Losses on some short-option positions can exceed the initial credit.
  3. 03
    Liquidity.
    Wide bid–ask spreads and thin markets can make exits expensive or difficult.
  4. 04
    Assignment.
    Short options may be assigned, sometimes before expiration. Know the resulting stock and cash obligations.
03 — Cultivate a process

Four habits before every position.

01

Define the thesis

Write down the expected direction, magnitude, and time horizon. If the thesis cannot be stated plainly, it is not ready.

02

Map the outcomes

Calculate the maximum gain, maximum loss, break-even points, and what happens at expiration.

03

Size for uncertainty

Use an amount whose loss would not impair essential savings, obligations, or the ability to follow the broader plan.

04

Plan the exit

Set the conditions for taking profit, reducing risk, accepting a loss, or closing before expiration.
