How much does a put option cost?
Also question is, what happens when you buy a put?
Let me "put" it to you this way To review, buying a put option gives you the right to sell a given stock at a certain price by a certain time. For that privilege, you pay a premium to the seller ("writer") of the put, who assumes the downside risk and is obligated to buy the stock from you at the predetermined price.
Also know, how much money can you lose on a put option?
Potential losses could exceed any initial investment and might amount to as much as the entire value of the stock, if the underlying stock price went to $0. In this example, the put seller could lose as much as $5,000 if the underlying stock went to $0 (as seen in the graph).
Stock Options—Puts Are More Expensive Than Calls. For almost every stock or index whose options trade on an exchange, puts (option to sell at a set price) command a higher price than calls (option to buy at a set price).
