+Option Fundamentals   • 15
+In this sold call example, we again see the shaded area representing 
+the exposure range. We also see that the exposure is limited to 500 days 
+and that it starts at the $60 strike price. The big difference we see between 
+this diagram and the one before it is that when we gained upside exposure 
+by buying a call, we had potentially profitable exposure infinitely upward; 
+in the case of a short call, we are accepting the possibility of an infinite 
+loss. Needless to say, the decision to accept such risk should not be taken 
+lightly. We will discuss in what circumstances an investor might want to 
+accept this type of risk and what techniques might be used to manage that 
+risk later in this book. For right now, think of this diagram as part of an 
+explanation of how options work, not why someone might want to use this 
+particular strategy.
+Let’s go back to the example of a long call because it’s easier for 
+most people to think of call options this way. Recall that you must pay a  
+premium if you want to gain exposure to a stock’s directional potential. In 
+the diagrams, you will mark the amount of premium you have to pay as a 
+straight line, as can be seen here:

+I have labeled the straight line the “Breakeven line” for now and have as-
+sumed that the option’s premium totals $2.50. 
+Y ou can think of the breakeven line as a hurdle the stock must cross 
+by expiration time. If, at expiration, the stock is trading for $61, you have 
+the right to purchase the shares for $60. Y ou make a $1 profit on this trans-
+action, which partially offsets the original $2.50 cost of the option.
