One problem with the S&P 500 is that it's a weighted index, meaning that larger companies contribute more to its performance. These days, massive tech stocks like ( 0.33%) and Microsoft make up a disproportionate amount of the index's weight.The Invesco S&P 500 Equal Weight ETF takes a different approach. It invests in the exact same 500 companies as other S&P 500 ETFs, but it invests an equal amount of money into each one. In other words, all 500 of the companies in the index get a 0.2% weighting in the fund -- no more, no less. This can be a good ETF to consider if you want a broad index fund but aren't comfortable with a large percentage of your performance dependent on just a handful of stocks., The SPDR Portfolio S&P 500 Growth ETF offers a more tactical approach to the S&P 500 by focusing solely on the growth stocks in the index.

The ETF charges 0.0945% per year in annual fees..
