There are 11 sectors making up the S&P 500 I:GSPC  . Each can be traded separately using an exchange-traded fund. Since the presidential election, the ETFs for materials, industrial, energy, financial and transportation provided stock market leadership. The industrial and transportation sector ETFs slowed down last week without setting new highs. Meanwhile, consumer discretionary and technology joined the leadership parade setting new 2016 highs.

Last week, the S&P 500 experienced additional upside and set an all-time intraday high of 2,277.53 on Dec. 13. The lagging sectors continue to be the "safety sectors" ETFs as real estate, consumer staples, health care and utilities.

Here's this week's scorecard for the 11 exchange-traded funds that represent each of the sectors of the S&P 500.
