How Put Options Work

Buying a Put Option gives you the right to sell a stock at a specific price (Strike Price) by a certain date. You profit if the stock price falls significantly below the Strike Price minus the Premium you paid.

The Formula

Cost = Premium × 100 × Contracts

Value = Max(Strike - Stock, 0) × 100 × Contracts

Profit = Value - Cost

Break-Even Point

To make money, the stock must fall below:

Strike Price - Premium

Example: Strike $100 - Premium $2 = Break-Even $98.

Uses for Puts

  • Speculation (Bearish)Betting that a stock is overvalued and will crash. High risk, high reward.
  • Protection (Hedging)If you own 100 shares of Apple but fear earnings will be bad, buying a Put acts as insurance. If stock drops 20%, your Put gains value, offsetting the loss on your shares.

Scenarios

Stock Crashes (Win)

If stock falls to $100 and strike is $140, option is worth $40. If premium was $4, take home $36 per share profit.

Stock Rises (Loss)

If the stock goes up, the Put expires worthless. Your max loss is limited to the premium paid, unlike shorting stock where loss is unlimited.

Put Option Profit Formula

To calculate your total profit at expiration, determine if the stock is below your strike price. If it is, you subtract the premium you paid from the intrinsic value, and multiply by 100.

StrikeThe price at which you have the right to sell the stock
StockThe final price of the underlying stock at expiration
PremiumThe price you originally paid per share for the put option
ContractsThe number of options contracts you purchased

Manual Step: Finding Profit on a Tesla Put

Suppose you buy 1 Put Option for TSLA with a $200 Strike Price. The premium costs $6.00. At expiration, TSLA has dropped to $180.

1
1. Calculate Gross Value
Because the stock is below the strike, your option has an intrinsic value of $20 per share.
2
2. Subtract Premium Paid
Subtract the $6 you paid to buy the contract. Your net profit is $14 per share.
3
3. Multiply by Multiplier
One contract represents 100 shares, so multiply by 100.
4
Result
You risked $600 to make a $1,400 net profit by betting against the stock.

Frequently Asked Questions

What is a Put Option?
A financial contract that gives the buyer the right, but not the obligation, to SELL a stock at a specified price (Strike Price) within a specific time period.
Why buy a Put instead of shorting the stock?
Buying a Put has strictly defined risk. The maximum you can lose is the premium you paid for the contract. If you short a stock, your potential loss is theoretically infinite if the stock price skyrockets.
Does the stock price have to go to zero to make money?
No. You start making a net profit as soon as the stock price drops below your 'Break-Even' point (Strike Price minus the Premium Paid).
