Where Does The Stock Market Go From Here? Sector Weightings Can Help

 | Nov 09, 2014 01:37AM ET

The ever-elusive $64,000 question of “Where does the stock market go from here?” is as popular a question today as it was a century ago. All you have to do is turn on CNBC to find an endless number of analysts, strategists, journalists, economists, and other talking heads guessing on the direction of stock prices. So many people are looking to make a quick buck or get a hot tip, but unfortunately investing is like dieting…it takes hard work and there are no simple solutions. As much as the pundits would like to make this investment game sound like a scientific certainty, in reality there is a lot of subjective art, experience, and luck that goes into successful investment outcomes. Consistent followers of Investing Caffeine understand there are a number of tools I use to guide me on the direction and level of stock prices, and three of my toolbox gizmos include the following:

  • Earnings (Stock prices positively correlated)
  • Interest Rates (Stock prices inversely correlated)
  • Sentiment (Stock prices inversely correlated)

While these and other devices (see ) are great for guesstimating the direction of longer-term stock prices, sector weightings are also great tools for identifying both overheated and unloved segments of the market. Take an extreme example, such as the S&P 500 Technology historical sector weighting in the year 2000. As you can see from the Bespoke Investment charts, the Technology sector went from about a 5% weighting of the overall market in the early 1990s to around 36% at the 2000 peak before dropping back down to 15% after the Tech Bubble burst. If you fast forward to the 2008-2009 Financial Crisis, we saw a similar “bubblicious” phenomenon rupture in the Financial sector. During 1980 the Financial segment accounted for approximately 5% of the total S&P 500 Index market capitalization in 1980 and skyrocketed to a peak of 23% in 2007, thanks in large part to a three decade bull-run in declining interest rates coupled with financial regulators asleep at the oversight switch.
