Benefits. Long-dated call options provide an alternative to stock ownership. You can benefit from any increase in the price of the underlying stock for the price of the premium rather than the substantially higher price of the stock. Long-dated call options also limit your risk.
Is it better to buy options with longer expiration date?
The farther out the expiration date, the more time you have for the trade to be profitable, but the more expensive the option will be. Thus, figuring out the balance between price and time until the contract expires is a key to success when buying or selling options.
When should I buy a long call option?
Market Conditions - a long call would be placed if you have a bullish assumption of the market/underlying; long call options are traded when an investor expects the underlying's price to have a significant move upwards.
