Buying a put gives you the right,but not the obligation to sell the underlying asset at a predetermined price( strike price)..
It's an insurance contract,but unlike insurance,there is a liquid market for the contracts..
Make believe you have a 1 million dollar house in California and are terrified of the fire risk. You want to protect the value of your house and find an insurance broker who offers you a contract where you are guaranteed to sell your house at 900k no matter what,but only for the next 2 years..
The question is how much would you pay to be assured if your house burns to the ground,you will receive 900k,I.e. 90 percent of the value of your house..
You may decide that you are good netting 850k if there is a disaster,which means you could offer the broker 50k for the 900k insurance contract...
If the broker agrees,you now have protection...
Let's say 1.5 years go by and there has been no sign of fire..At the same time,a,you are short of cash and feel comfortable selling your insurance contract back to the broker...you call him up and ask if he would like to relieve himself of his 900k exposure.He may say since there are only 6 months left on the contract and no sign of fire,he would give you 4k...Unforrunately, that number is too low for you and you decline..
3 months later,a huge brush fire breaks out and the fire is heading directly for your area..You get a text from your broker asking if you still would take 4k for letting him out of the 900k insurance contract..
You look out the window and see a massive ball of flame 1000 yards from the house..Woyld you let the broker out of the contract for 4k,or as the flames head closer,would you ask for 700k or even more???
That's how Puts work
Buying a put equates to short selling? Thereafter, the trader will sell a put at a lower price (compared to his buy put price) to make a profit. Is this understanding correct?
