Trade S&P Options
The S&P or the Standards & Poors 500 is the weighted index of USA’s 500 large cap common stocks that are actively traded. The S&P options therefore are option contracts that have the underlying value based on the level of the S&P 500. The S&P 500 index option contracts have a value that is equivalent to the full value of the S&P index’s level. Traded under the symbol of SPX, the S&P index options have a contract multiplier of $100. The S&P index option is basically a European style option and therefore the last business day before the expiration date is the time when the option may be exercised.
How to trade S&P options
Just as is the case with the usage of options in various trading commodities, the same is here in case of the S&P. If a trader anticipates the value of the S&P index options to rise in the near future, he may buy a call option. Whereas if he believes that the value of the S&P index would fall in the future, he may buy the puts option.
To explain the process of how to trade S&P options, here is an example:
The current level of the S&P index is $951.49. Since the SPX is based on the entire value of the underlying S&P index, it trades at $951.49. A trader buys the call option with the expiration date a month away. The strike price of $960 is priced at $64.40. Since the contract multiplier of an S&P index option is $100, the premium that the trader has to pay to purchase the call option is $6,440.
It is assumed that on the expiration day, the underlying S&P 500 index’s level has risen by 15% to $1,094.19. The SPX is correspondingly now trading at $1094.19 because the full value of the underlying S&P is the basis of the SPX. With significant increase in the SPX over the option strike price of $960, the call option ends “in the money”. This means that the trader can now exercise his call option and will receive the cash amount that is calculated based on the following formula:
Cash Settlement Amount = (Difference between Index Settlement Value and the Strike Price) x Contract Multiplier
Therefore the trader receives (1094.19 – 960.00) x $100 = $13,419 when he exercises his call option. The trader had initially paid the premium of $ 6,440. Deducting this amount from the final payment received, the trader still makes a profit of $6979 from his long call strategy.
The advantage of trading S&P options is the fact that the trader’s loss is limited to the amount of money paid for the purchase of SPX call option. This means in the above example, if the SPX had fallen by 15% rather than rising, the trader would not exercise his option. This way he would limit his loss to the tune of $6440 that he had spent in the process of obtaining the option. Here it is important to remember that the options contract allows the trader to exercise his option only if conditions are favorable. Unlike the futures contract where the trader is under the obligation to buy or sell, the options contract provides the trader the right but not any obligation to exercise his option.
