Options - Trading mechanism

If you are optimistic about the underlying, you can buy a call option or write a put option.

If you are negative about the underlying, you can choose to buy a put option or write a call option.



If you are positive about the underlying

If an investor wants to buy a call option, he needs to pay a premium upfront.  In case the underlying price does rise above the strike price, the investor can exercise the option to earn the difference.

If the investor chooses to write a put option, he will receive a premium.  If the underlying price climbs above the strike price, the put option will become worthless (and not exercised), leaving the premium safe in the hands of the investor.  In writing a put option, the investor is required to deposit a margin and face the risk of unlimited loss (in theory), the underlying price can drop to zero).

If you are negative about the underlying

If the investor chooses to buy a put option, he needs to pay a premium upfront.  In case the underlying price does fall below the strike price, the investor can exercise the option to earn the difference.

If the investor chooses to write a call option, and if the underlying price falls below the strike price, he will pocket the full amount of the premium.  On the other hand, if the underlying price is higher than the strike price, he will face the risk of unlimited loss (in theory, the underlying price can go up indefinitely).


Warrants versus Options

In the case of warrants, the investor can only be a buyer, and choose between call warrants or put warrants.  The seller is always the issuer.

While options offer more possibilities, the risk is also much bigger.  In contrast, warrants are only subject to limited risk exposure.
