Options Foundations · Options Trading Guide
Begin with the four basic positions. A call or put describes a right, while buying or selling determines whether you hold that right or accept an obligation.
Separate the contract from the position
A call gives its holder the right to buy the underlying at the strike under the contract terms. A put gives the right to sell. The buyer pays a premium. The writer receives it and accepts the corresponding obligation if assigned. Selling an existing long option to close is different from opening a new short position. Always identify both the option type and whether the trade opens or closes exposure.
Follow a fictional call
Assume a standard contract covers 100 shares. You buy a 50 strike call for $3 per share, paying $300. At expiration with the stock at $58, its intrinsic value is $800. Subtracting the premium leaves $500 gross profit. At $49, the contract expires without intrinsic value and the $300 premium is lost. Being right about direction is insufficient if the move is too small or too late.
Compare the other side
The writer of that same call has the opposite option payoff before costs. Without shares or another effective hedge, a rising stock can create an unlimited loss. A purchased put has a maximum option loss equal to its premium, while a written equity put can lose almost the strike value times the multiplier if the stock falls to zero. Receiving cash is therefore not the same as earning a completed profit.
Choose the correct vocabulary
Long call and short put commonly create positive directional exposure. Long put and short call commonly create negative exposure. Their payoff shapes and obligations still differ. Write a position as action, quantity, underlying, call or put, strike and expiration. Add the premium and multiplier. This compact description makes it possible to reconstruct the trade instead of relying on labels such as bullish or income. The examples throughout this guide are fictional and use standard contracts unless stated otherwise.
Try it yourself
A 40 strike put costs $2 per share and covers 100 shares. At expiration the stock is $35. What is the buyer’s gross profit?
Show the worked answer
Intrinsic value is $5 per share, or $500. Subtract the $200 premium to obtain $300 gross profit before costs.
