+Chapter 30: Stock Index Hedging Strategies 541 
+or adjusted capitalization, in order to compensate for the higher volatility of the port­
+folio. 
+A similar process can be used for far larger portfolios. The estimate of volatili­
+ty is, of course, crucial in these calculations, but as long as one is consistent in the 
+source from which he is extracting his volatilities, he should have a reasonable hedge. 
+There is no way to judge the future performance of a portfolio of stocks versus the 
+ZYX Index. Thus, one has to expect a rather large tracking error. In this type of 
+hedge, one hopes to keep the tracking error down to a few percent, which could be 
+several points in the futures contracts over a long enough period of time. Of course, 
+the tracking error can work in one's favor also. The main point to recognize here is 
+that the vast majority of the risk of owning the portfolios has been eliminated by sell­
+ing the futures contracts. The upside profit potential of the portfolios has been elim­
+inated as well, but the premise was that the investor was bearish on the market. 
+Note that if the futures are overpriced when one enacts his bearishly-oriented 
+portfolio hedge, he will gain an additional advantage. This will act to offset some neg­
+ative tracking error, should such tracking error occur. However, there is no guaran­
+tee that overpriced futures will be available at the time that the investor or portfolio 
+manager decides to tum bearish. It is better to sell the futures and establish the 
+hedge at the time one turns bearish, rather than to wait and hope that they will 
+acquire a large premium before one sells them. 
+HEDGING PORTFOLIOS WITH INDEX OPTIONS 
+As mentioned earlier, one could substitute options for futures wherever appropriate. 
+If he were going to sell futures, he could sell calls and buy puts instead. In this sec­
+tion, we are also going to take a more sophisticated look at using index options against 
+stock portfolios. 
+First, let us examine how the investor from the previous example might use 
+index options to hedge his portfolio. 
+Example: Suppose that an investor owns the same portfolio as in the previous exam­
+ple: 3,000 COCO, 5,000 UTIL, and 2,000 OIL. He decides to hedge with index 
+UVX, which has options worth $100 per point. Assume that the volatility of the UVX 
+is 15%. This investor would then compute his total adjusted capitalization in the same 
+manner as in the previous example, again arriving at a figure of $720,000. 
+Suppose that the UVX Index is at 175.60. This investor would want to hedge his 
+$720,000 of adjusted capitalization with 4,100 "shares" of UVX ($720,000 + 175.60). 
+Since a 1-point move in UVX options is worth $100, this means that one would sell 
+41 UVX calls and buy 41 UVX puts. He would probably use the 175 strike or possi-
