# Buying a Put Option- how it is done

We relate our explanation to an example:

Given that:

1.  We buy a Put option “June 90 P H”, which means: An option to sell a house in June for \$90K.

2.  The price of houses on the date of purchase of the option (Date A) – \$95K.

3.  We pay a premium of \$8K for the option.

We will examine what our profit or loss will be on the transaction via 3 scenarios, regarding the price of houses in the market at expiry of the option (Date B).

Scenario 1 – Market price of houses is \$80K

Under this scenario it is worthwhile exercising the option.

We can buy a house in the market for \$80K and sell it in the stock market for a price of  \$90K. Thus, the profit on the option will be \$10K.

In order to find the profit on the transaction, we subtract the premium we paid, \$8K, leaving a total profit of \$2K.

Scenario 2 – Market price of houses is \$110K

Under this scenario we will not exercise the option. It is not worthwhile to purchase a house in the market for \$110K in order to sell it in the stock market for \$90K. We will lose \$20K. Under this scenario, the option profit in 0, but on the transaction as a whole we lose the entire premium, a loss of \$8K.

Scenario 3 – Market price of houses is \$85K

Under this scenario it is worthwhile exercising the option. We make a profit of \$5K on it, since we can purchase a house in the market for \$85K and sell it in the stock market for \$90K. Since we paid a premium of \$8K, we make a loss of only \$3K on the transaction.

If we do not exercise the option, we would lose \$8K on the transaction.

As we can see, we make a profit on the option only if we can buy for cheap and sell at a higher price, which happens when the market price is lower than the exercise price.

## Buying Put options – Main characteristics

The basic use of Put options is when we expect a decrease in the prices of the underlying asset.

2.  In respect of just the option itself, we can only profit. If we don’t make a profit, we don’t exercise the option.

3.  In respect of the transaction as a whole, the loss is limited to the amount of the premium only.
