bespoke<> S&P 500 Sector Weightings

Wednesday, June 16, 2010 at 11:39AM

Below we take a look at historical and current sector weightings of the S&P 500. Technology is currently the biggest sector in the index at 18.9%, and it has been the biggest since it overtook the Financial sector early on in the financial crisis. There has been quite a bit of movement in sector weightings in recent years. At the bear market low in March 2009, the Financial sector made up just 8.9% of the index. It has charged back since then and has nearly doubled its weighting to 16.3%. Consumer Discretionary, Industrials, and Technology are the only other sectors that have increased their weightings during the current bull market. Health Care has really dropped off, going from 16.1% at the bear market low to its current level of 11.8%. Energy has also dropped quite a bit from 14.3% to 11%. There are now five sectors with weightings that are between 10.5% and 11.8%. Utilities, Materials, and Telecom continue to have very low weightings, and combined they still make up less than the 7th largest sector. The performance of any of these three sectors has a very minimal impact on the overall direction of the market.
