FYI: Below is an updated look at sector weightings for the S&P 500. As shown, Technology remains the largest sector of the market at 19.32% -- pretty much a fifth of the market. The Financial sector is the second largest with a weighting of 16.41%, followed by Health Care at 13.89%. Consumer Discretionary ranks fourth at 11.74%, Industrials is in fifth at 10.41%, and Consumer Staples is sixth at 9.80%. The Energy sector currently has a weighting of 9.42%, which is down significantly this year. The bottom three sectors make up just 9% of the index, so together they don't add up to Energy's weighting in seventh place.
