588 SUMMARY Part V: Index Options and Futures This concludes the discussion of index spreading. The above examples are intended to be an overview of the most usable strategies in the complex universe of index spreading. The multitude of strategies involving inter-index and intra-index spreads cannot all be fully described. In fact, one's imagination can be put to good use in designing and implementing new strategies as market conditions change and as the emotion in the marketplace drives the premium on the futures contracts. Often one can discern a usable strategy by observation. Watch how two popu­ lar indices trade with respect to each other and observe how the options on the two indices are related. If, at a later time, one notices that the relationship is changing, perhaps a spread between the indices is warranted. One could use the NASDAQ­ based indices, such as the NASDAQ-100 (NDX) or smaller indices based on it (QQQ or MNX). Sector indices can be used as well. This brings into play a fairly large num­ ber of indices with listed options (few, if any, of which have futures), such as the Semiconductor Index (SOX), the Oil & Gas Index (XOI), the Gold and Silver Index (XAU), etc. The key point to remember is that the index option and futures world is more diverse than that of stock options. Stock option strategies, once learned or observed, apply equally well to all stocks. Such is not the case with index spreading strategies. The diversification means that there are more profit opportunities that are recognized by fewer people than is the case with stock options. The reader is thus challenged to build upon the concepts described in this part of the book.
