Sir/mam I have confusion related to call/put premium in stock market.There is an example. I am confused that after rising price he will purchase share in Rs70 and sell it Rs78 and book his profit or the balance of premium i.e. (8.25-3.15) will be his profit.
Let's say that on May 1, the stock price of Cory's Tequila Co. is $67 and the premium (cost) is $3.15 for a July 70 Call, which indicates that the expiration is the third Friday of July and the strike price is $70. The total price of the contract is $3.15 x 100 = $315. In reality, you'd also have to take commissions into account, but we'll ignore them for this example.
Remember, a stock option contract is the option to buy 100 shares; that's why you must multiply the contract by 100 to get the total price. The strike price of $70 means that the stock price must rise above $70 before the call option is worth anything; furthermore, because the contract is $3.15 per share, the break-even price would be $73.15.
When the stock price is $67, it's less than the $70 strike price, so the option is worthless. But don't forget that you've paid $315 for the option, so you are currently down by this amount.
Three weeks later the stock price is $78. The options contract has increased along with the stock price and is now worth $8.25 x 100 = $825. Subtract what you paid for the contract, and your profit is ($8.25 - $3.15) x 100 = $510. You almost doubled our money in just three weeks! You could sell your options, which is called "closing your position," and take your profits - unless, of course, you think the stock price will continue to rise.
