Options Basics
From "what is an option" to placing your first simple option trade with clear eyes
A plain-English, India-first introduction to options. Start from the single idea of a right without an obligation, build up through premium, moneyness, the option chain, expiry, time decay, and the Greeks, and finish ready to practise the four basic positions with honest risk in view.
Part 1
The idea of an option
- 1What is an optionAn option is the right, not the duty, to buy or sell an underlying at a fixed strike by a fixed expiry, bought for a premium that is the buyer's most to lose. 8 min
- 2Why options existPeople buy options for two honest reasons: to back a view with a small, fixed, known risk, and to protect a holding like insurance. The premium is the price of both. 8 min
- 3Calls and putsA call is the right to buy, chosen when you expect a rise. A put is the right to sell, chosen when you expect a fall or want protection. In India, CE marks a call and PE a put. 7 min
- 4Premium, strike, and expiryEvery option carries a premium you pay, a strike you lock, and an expiry you race, all written on an underlying. You can read them straight off an Indian option name. 8 min
- 5Buyer versus sellerAn option has a buyer who pays the premium and risks only that, and a seller who collects the premium but takes on the obligation and much larger risk. Time helps the seller and hurts the buyer. 8 min
Part 2
Reading an option's value
- 6Intrinsic and time valueEvery premium splits into two parts: intrinsic value, the real settle-now worth, and time value, the price of hope. Time value melts to zero by expiry. 8 min
- 7MoneynessMoneyness sorts options by intrinsic value into in-the-money, at-the-money, and out-of-the-money. It is a mirror image for calls and puts, and out-of-the-money options are cheap for a reason. 8 min
- 8The option chainThe option chain lists every strike for one underlying and expiry, calls on one side and puts on the other. Find the at-the-money row and moneyness and premiums fall into place. 8 min
- 9Lots and contract valueOptions are quoted per share but traded in fixed lots, so one lot costs the premium times the lot size. The contract value, price times lot size, is the larger exposure behind it. 8 min
- 10Index versus stock optionsIndex options are cash-settled, diversified, and usually liquid. Stock options track one company and, in India, settle by physical delivery at expiry, which can surprise the unprepared. 8 min
Part 3
Expiry, payoff, and the clock
- 11Expiry, exercise, and settlementAt expiry, in-the-money options settle for intrinsic value and out-of-the-money options expire worthless. The buyer exercises, the seller is assigned, and settlement is cash for index options and delivery for stock options. 8 min
- 12Payoff at expiryA payoff diagram shows an option's profit or loss at expiry across every price of the underlying. A long call has capped loss and open-ended gain; a long put, capped loss and a large bounded gain. 8 min
- 13Payoff versus live profit and lossThe payoff diagram is the expiry story, intrinsic value only. Before expiry, your live profit and loss is the current premium minus your cost, and time and volatility move it, so you can be right on direction and still lose. 7 min
- 14Time decayTime decay is the steady loss of an option's time value as expiry nears, accelerating in the final days. It works against buyers and for sellers, and it is the mechanical reason most short-dated buyers lose. 8 min
Part 4
What moves an option's price
- 15What moves an option's priceThree forces move an option's premium: the underlying's price, the passage of time, and expected volatility. Only the first is direction, which is why time and volatility can beat a correct call. 7 min
- 16DeltaDelta is how much an option's premium moves per one-rupee move in the underlying, running 0 to 1 for calls and 0 to minus 1 for puts. It also reads roughly as the chance of finishing in-the-money. 7 min
- 17ThetaTheta is time decay as a daily number, negative for the buyer and positive for the seller, growing as expiry nears. A buyer needs delta's gains to outrun theta's daily bleed. 7 min
- 18Vega and volatilityImplied volatility is the market's expectation of movement, baked into the premium, so high volatility means fat premiums. Vega measures the effect, and the volatility crush after an event catches buyers. 8 min
- 19Gamma and the restGamma is how fast delta changes, highest at-the-money and near expiry. Rho is minor for a beginner. The practical goal is to feel the three main forces, delta, theta, and vega, not to compute them. 7 min
Part 5
Trading options safely
- 20The long callA long call is a bet the underlying rises enough, soon enough. Maximum loss is the premium, breakeven is strike plus premium, and gain above it is open-ended. It loses if the move is too small, too slow, or bought at high volatility. 8 min
- 21The long putA long put profits from a fall with loss capped at the premium, the limited-risk way to bet on a decline. Bought against shares you own, it is insurance, a protective put that sets a floor. 8 min
- 22Selling optionsSelling an option collects the premium but takes on an obligation, a capped reward against large or unlimited risk. Time decay favours the seller, but one big move can erase many premiums. Beginners should sell only defined-risk forms, if at all. 9 min
- 23How option traders loseOptions add their own ways to lose: cheap far-out-of-the-money tickets, ignoring time decay, buying into high volatility, oversizing by the per-share premium, and naked selling. Each has a guardrail. 8 min
- 24From learning to practiceA pre-trade checklist folds the whole course into eight questions. Then rehearse the basic positions in the practice sandbox until the mechanics and the forces are second nature, before risking real money. 8 min
