+Cbapter 30: Stock Index Hedging Strategies 547 
+paid out and, if the market stabilizes, the time value decay will cause a loss on the 
+puts. If one actually suspects that such a stabilization might occur, he should use 
+futures against his position instead of puts or calls. 
+INDEX ARBITRAGE 
+As previously stated, index arbitrage consists of buying virtually all of the stocks in an 
+index and selling futures against them, or vice versa. Whenever the futures on an 
+index are mispriced, as determined by comparing their actual value with their fair 
+value, there may be opportunities for arbitrage if the mispricing is large enough. 
+When futures are extremely overpriced: buy stocks, sell futures; or when futures are 
+underpriced: sell stocks, buy futures. In either case, the arbitrageur is attempting to 
+capture the differential between the fair value price of the futures contract and the 
+price at which he actually buys or sells the index. First, we will examine fully hedged 
+situations - ones in which the entire index is bought or sold. After that, we will exam­
+ine smaller sets of stocks that are designed to simulate the performance of the entire 
+index. 
+Hedging indices which contain fewer stocks is easier than hedging larger 
+indices. Hedging a price-weighted index is probably the simplest type of hedge. As 
+examples, the same sample indices that were constructed in the previous chapter will 
+be used. 
+Whenever futures or index options trade on an index, it is possible to set up 
+market baskets for arbitrage. The trader should determine, in advance, how many 
+shares of each stock he will buy or sell in order to duplicate the index. In a price­
+weighted index, of course, he will buy the same number of shares of each stock. In a 
+capitalization-weighted index, he will be buying different numbers of shares of each 
+stock. Let us first look at how the number of shares to buy is determined. Then we 
+will discuss some of the nuances, such as monitoring bids and offers of the indices, 
+order execution, and others. 
+HOW MANY SHARES TO BUY 
+In advance of actually trading the stocks and futures or options, one should deter­
+mine exactly how many shares of each stock he will be buying in each index he plans 
+to arbitrage. Normally, one would decide in advance how many futures contracts or 
+option contracts he will trade at one time. Then the number of shares of stock to be 
+bought as a hedge can be determined as well. Essentially, one is going to hedge equal 
+dollar amounts - that is, he will buy enough stocks to offset the total dollar amount 
+represented by the index.
