One of the most striking lessons of the 1980s is that all markets are interrelated—financial and nonfinancial, domestic and international. The U.S. stock market doesn't trade in a vacuum; it is heavily influenced by the bond market. Bond prices are very much affected by the direction of commodity markets, which in turn depend on the trend of the U.S. dollar. Overseas markets are also impacted by and in turn have an impact on the U.S. markets. Events of the past decade have made it clear that markets don't move in isolation. As a result, the concept of technical analysis is now evolving to take these intermarket relationships into consideration. Intermarket technical analysis refers to the application of technical analysis to these intermarket linkages.

The idea behind intermarket analysis seems so obvious that it's a mystery why we haven't paid more attention to it sooner. It's not unusual these days to open a financial newspaper to the stock market page only to read about bond prices and the dollar. The bond page often talks about such things as the price of gold and oil, or sometimes even the amount of rain in Iowa and its impact on soybean prices. Reference is frequently made to the Japanese and British markets. The financial markets haven't really changed, but our perception of them has. Think back to 1987 when the stock market took its terrible plunge. Remember how all the other world equity markets plunged as well. Remember how those same world markets, led by the Japanese stock market, then led the United States out of those 1987 doldrums to record highs in 1989 (see Figure 1.1). Turn on your favorite business show any morning and you'll get a recap of the overnight developments that took place overseas in the U.S. dollar, gold and oil, treasury bond prices, and the foreign stock markets. The world continued trading while we slept and, in many cases, already determined how our markets were going to open that morning.

A COMPARISON Of THE WORLD'S THREE LARGEST EQUITY MARKETS: THE UNITED STATES, JAPAN, AND BRITAIN. GLOBAL MARKETS COLLAPSED TOGETHER IN 1987. THE SUBSEQUENT GLOBAL STOCK MARKET RECOVERY THAT LASTED THROUGH THE END OF 1989 WAS LED BY THE JAPANESE MARKET.

ALL MARKETS ARE RELATED

What this means for us as traders and investors is that it is no longer possible to study any financial market in isolation, whether it's the U.S. stock market or gold futures. Stock traders have to watch the bond market. Bond traders have to watch the commodity markets. And everyone has to watch the U.S. dollar. Then there's the Japanese stock market to consider. So who needs intermarket analysis? I guess just about everyone; since all sectors are influenced in some way, it stands to reason that anyone interested in any of the financial markets should benefit in some way from knowledge of how intermarket relationships work.

IMPLICATIONS FOR TECHNICAL ANALYSIS

Technical analysis has always had an inward focus. Emphasis was placed on a particular market to which a host of internal technical indicators were applied. There was a time when stock traders didn't watch bond prices too closely, when bond traders didn't pay too much attention to commodities. Study of the dollar was left to interbank traders and multinational corporations. Overseas markets were something we knew existed, but didn't care too much about.

It was enough for the technical analyst to study only the market in question. To consider outside influences seemed like heresy. To look at what the other markets were doing smacked of fundamental or economic analysis. All of that is now changing. Intermarket analysis is a step in another direction. It uses information in related markets in much the same way that traditional technical indicators have been employed. Stock technicians talk about the divergence between bonds and stocks in much the same way that they used to talk about divergence between stocks and the advance/decline line.

Markets provide us with an enormous amount of information. Bonds tell us which way interest rates are heading, a trend that influences stock prices. Commodity prices tell us which way inflation is headed, which influences bond prices and interest rates. The U.S. dollar largely determines the inflationary environment and influences which way commodities trend. Overseas equity markets often provide valuable clues to the type of environment the U.S. market is a part of. The job of the technical trader is to sniff out clues wherever they may lie. If they lie in another market, so be it. As long as price movements can be studied on price charts, and as long as it can be demonstrated that they have an impact on one another, why not take whatever useful information the markets are offering us? Technical analysis is the study of market action. No one ever said that we had to limit that study to only the market or markets we're trading.

Intermarket analysis represents an evolutionary step in technical analysis. Intermarket work builds on existing technical theory and adds another step to the analytical process. Later in this chapter, I'll discuss why technical analysis is uniquely suited to this type of investigative work and why technical analysis represents the preferred vehicle for intermarket analysis.
