What is a call option contract?

Call option is the contract in which, buyer has a right to buy shares of number at strike price before an expiry date.

In this, the buyer has no right for an obligation.

In this option, premium is paid for risk associated with an obligation.

These are purchased mainly for speculation and are sold for income purposes.

If the security price is more than the purchase price then, an option is profitable (buying the stock at a lower price than market value).

If the security price is lower than the purchase price, then the option is not profitable.

Long call option

In this before expiry date, market price (asset) will increase substantially beyond strike price. This is the most call option employed by investors in buying an option. To buy this option the buyer has to pay a premium amount to the broker.

In case of speculation, buyers will buy these options in anticipation of profits in future. If the price is below the current price then the buyer will lose premium amount and amount paid for agreement.

Short call option

An investor sells an option when the investor purchases assets at a predetermined price. Profits in this call are limited when shares are traded below strike price. This short call is suitable for assets which are expected to have moderate fall. This strategy generates upfront credit and may be effective in offsetting margin.
