The news recently reports dismal economic numbers. At the same time, they report record gains for the stock market. What is going on?
If you break the S&P 500 index down by sector, you can see numbers that make more sense given the current economic climate: Year-to Date numbers for some of the worst performing areas (shown in Figure 1) include: Department stores down -62.6%; Airlines down 55%; Travel services at -51.4%; Oil & gas equipment/services not doing well at -50.5%; Resorts and casinos with -45.4%; and Hotel REITS at -41.9%. Meanwhile, the top ten technology companies in the index have gained more than 37%.
Figure 1: The S&P 500 Index vs. Selected Sector Performance
The S&P 500 is what’s called a “market-capitalization index”. Market capitalization reflects the size of a company. A larger company means its returns count for more in the index. Here, department stores fell 62.3%, but on a market-cap basis they are only 0.01% of the S&P 500. In contrast, the sectors that currently drive the positive returns in the S&P500 come from four areas –internet content, software infrastructure, consumer electronics and internet retailers. These account for more than $8 trillion in market value – that’s almost one quarter of the total value of the market.
When comparing the total returns (total returns includes the stock price and the dividends) of the standard, market-cap weighted S&P 500, the return is up 2.38% for the year. If we compare that to the equal weight S&P 500, we can see the returns are at -6.45% for the year. See Figure 2.

Many people “just buy an index” but do not fully understand what they are buying.
