16  •   The Intelligent Option Investor It is important to note that a stock does not have to cross this line for your option investment to be profitable. We will discuss this dynamic in Chapter 2 when we learn more about the time value of options. Visual Representation of Put Options Now that you understand the conventions we use for our diagrams, let’s think about how we might represent the other type of option, dealing with downside exposure—the put. First, let’s assume that we want to gain expo- sure to the downside potential of a stock. Graphically, we would represent this in the following way: 5/18/2012 - 20 40 60 80 100 120 140 160 180 200 5/20/2013 249 499 Date/Day Count Stock Price 749 999 GREEN First, notice that, in contrast to the diagram of the call option, the directional exposure of a put option is bounded on the downside by $0, so we do not draw an arrow indicating infinite exposure. This is the same downside exposure of a stock because a stock cannot fall below zero dollars per share. In this diagram, the time range for the put option is the same 500 days as for our call option, but the price range at which we have exposure starts at a strike price of $50—the current market price of the stock—making this an at-the-money (ATM) put. If you think about moneyness in terms of a range of exposure, the difference between out of the money (OTM) and in the money (ITM) becomes easy and sensible. Here are examples of differ- ent moneyness cases for put options:
