Sometimes there really isn’t too much going on in the market, and as I write this the S&P 500 (SPX) is literally unchanged so today is one of those days.
One question we get a lot is what sectors make up the S&P 500, and how the current construction of the index by sector percentage compares to history. Figure 1 shows the current sector percentages in the SPX with the historical mean since 1989 in parenthesis. To show an example, the Technology sector currently makes up 20.6% of the SPX vs. a historical mean of 14.7%. This is just an FYI so that when you hear about a sector that is catching investors attention either way, you can see how it stacks up relative to its history.
