+106 Part II: Call Option Strategies 
+such an analysis for themselves, the details of computing a stock's volatility and pre­
+dicting the call prices are provided in Chapter 28 on mathematical techniques. 
+OVERPRICED OR UNDERPRICED CALLS 
+Formulae exist that are capable of predicting what a call should be selling for, based 
+on the relationship of the stock price and the striking price, the time remaining to 
+expiration, and the volatility of the underlying stock. These are useful, for example, 
+in performing the second step in the foregoing analysis, estimating the call price after 
+an advance in the underlying stock. In reality, a call's actual price may deviate some­
+what from the price computed by the formula. If the call is actually selling for more 
+than the "fair" ( computed) price, the call is said to be overvalued. An undervalued 
+call is one that is actually trading at a price that is less than the "fair" price. 
+If the calls are truly overpriced, there may be a strategy that can help reduce 
+their cost while still preserving upside profit potential. This strategy, however, 
+requires the addition of a put spread to the call purchase, so it is beyond the scope 
+of the subject matter at the current time. It is described in Chapter 23 on spreads 
+combining calls and puts. 
+Generally, the amount by which a call is overvalued or undervalued may be only 
+a small fraction of a point, such as 10 or 20 cents. In theory, the call buyer who pur­
+chases an undervalued call has gained a slight advantage in that the call should return 
+to its "fair" value. However, in practice, this information is most useful only to mar­
+ket-makers or firm traders who pay little or no commissions for trading options. The 
+general public cannot benefit directly from the knowledge that such a small discrep­
+ancy exists, because of commission costs. 
+One should not base his call buying decisions merely on the fact that a call is 
+underpriced. It is small solace to the call buyer to find that he bought a "cheap" call 
+that subsequently declined in price. The method of ranking calls for purchase that 
+has been described does, in fact, give some slight benefit to underpriced calls. 
+However, under the recommended method of analysis, a call will not automatically 
+appear as an attractive purchase just because it is slightly undervalued. 
+TIME VALUE PREMIUM IS A MISNOMER 
+This is a topic that will be mentioned several times throughout the book, most 
+notably in conjunction with volatility trading. It is introduced here because even the 
+inexperienced option trader must understand that the portion of an option's price 
+that is not intrinsic value - the part that we routinely call "time value premium" - is 
+really composed of much more than just time value. Yes, time will eventually wear
