3. 3  Option overwriting refers to the creation and sale of stock options in conjunction with a stock portfolio.  The most common purpose is to generate additional portfolio income.  The second motivation for writing options is to permit the purchase or sale of stock at a better-than-market price. Overwriting

4.  When investors write call options against stock they already own, the call is said to be covered. Writing Options to Generate Income Initial XYZ stock price = $116 $120 call premium = $6 Stock price at option expiration Profit Loss 10 0 -110 120110 maximum loss = $110 maximum gain = $10 breakeven point = $110 4

5. 5  Improving on the market involves writing deep-in-the-money put or call options that have “substantial” intrinsic value.  Selling stock: Current XYZ stock price = $116 Write $100 call premium @ $18 If option is exercised, total income = $100 + $18 = $118 > income without overwriting = $116 Overwriting : Improving on the Market

6. 6  Buying stock: Current Intel stock price = $67 Write $75 put premium @ $9 If option is exercised, total cost = $75 - $9 = $66 < cost without overwriting = $67  Deep-in-the-money options can be used to improve a buying or selling price at the cost of a slight increase in risk.

7. 7  Portfolio protection basically involves adding adding components to a portfolio such that a floor value is established below which the value of the portfolio will not fall.  Writing covered calls provide downside protection up to the amount of the premium.  If an investor owns shares of a particular stock (long stock position) and buys a put on that same stock (long put position), the put is called a protective put. Portfolio Protection

8. 8  Using index options : An index put can protect a diversified stock portfolio against a market downturn. If market prices decline, a gain on the puts can largely offset the losses on the stock portfolio.  Using index futures contracts : A short futures position can help offset a long stock position. If the market falls, a gain in the futures market can largely offset the loss on the stock portfolio, and vice versa if the market rises. Portfolio Protection
