Since April 30, 1945, the S&P 500 rose in price an average 1.4% from May through October, compared to an average 6.8% from November through April, writes Todd Rosenbluth, S&P Global Market Intelligence Director of ETF Research, in a research note.

“From the bad news perspective comes the massive volatility and uncertainty evident in the stock market in the opening months of 2016. The Standard & Poor’s (S&P) 500 Index barely managed a positive gain of 1% for the first quarter of the year. These market conditions signal that investing in growth stocks is a riskier endeavor, and many investors are instead looking to adopt a defensive stance or hedging their investments by securing some dividend income. The Consumer Staples Select Sector SPDR ETF fulfills both of those desires; consumer staples stocks are generally considered a defensive investment, one with relatively lower volatility. Many consumer staples stocks, including this ETF, offer a solid dividend yield,” according to Investopedia.

Staples ETFs such as XLP, the largest consumer staples ETF on the market, and rivals, including the Vanguard Consumer Staples ETF (NYSEArca: VDC) and the Fidelity MSCI Consumer Staples Index ETF (NYSEArca: FSTA), could be investor favorites if polls show a highly competitive presidential election as the summer months drag along.

“When equity market uncertainty rises, Consumer Staples typically outperforms while Information Technology lags. From a factor perspective, the past decade shows that when equity market uncertainty increases, stocks with high dividend yield and low volatility outperform. In contrast, both high growth stocks and low valuation companies underperform their respective counterparts,” according to part of a Goldman Sachs note posted by Ben Levisohn of Barron’s.
