  1. A Primer on Call and Put Options OLLI Class Fall, 2011

  2. Call options • A listed call option on an individual stock is a contract that allows the call buyer to • buy from the call option seller (or writer) • 100 shares of a specified stock • at a specified price (striking price) • any time before the date of expiration • by paying a premium to the option seller

  3. Put options • A listed put option is a contract which allows the put buyer to: • sell to the put option seller (writer) • 100 shares of a specified stock • at a specified price (striking price) • any time before the date of expiration • by paying a premium to the option seller

  4. Essential terms • The buyer of a put or call has a long position in the option and the right of exercise. • The call seller has a short position and has the obligation to sellthe stock if assigned. • The put seller is short the put and must buy the stock if assigned.

  5. American or European Style • All listed options can be traded prior to expiration, but: • American options can be exercised anytime prior to expiration. All listed equity options and the OEX (S&P100) are American options. • European options can be exercised only at expiration. Most index options are European style options. • All else equal, an American option will have a higher premium than the identical European option

  6. Types of Options Available • Individual equity/stock options • Index Options • Broad Based (S&P 500, DJIA, S&P 100) • Sector indexes • LEAPS (long term options up to 2 years) • FLEX options (customized contracts) • Interest Rate options • Foreign Currency options
