Are Defensive Sectors Still Defensive?

It's no secret that defensive industry sectors like consumer staples and utilities have been leading major U.S. stock market benchmarks to all-time new highs. But have stocks in these sectors become overvalued?

The Consumer Staples Select Sector SPDR ETF (NYSEARCA:XLP) tracks 42 companies within the S&P 500 involved in food and beverage, drug retailing,  household, and personal consumer products.

Among the stocks within XLP that have valuations exceeding the broader market include Hershey (NYSE:HSY) with a P/E ratio of 29, Colgate-Palmolive (NYSE:CL) at 23, and Kellogg Co. (NYSE:K) at 23. By comparison, the SPDR S&P 500 ETF (NYSEARCA:SPY) carries a P/E ratio of around 15.

The list of boring consumer stocks selling at a premium to the market has pushed the entire staples sector to a P/E level over 17, according to Alta Vista Research. That makes XLP the richest valued sector among the SPDR ETFs tracking the other eight S&P 500 sectors.

The P/E or price earnings ratio measures stock valuations. It's calculated by taking a stock's market price divided by its annual earnings per share.

For instance, if a company is currently trading at $40 a share and earnings over the last 12 months were $1.50 per share, the P/E ratio for the stock would be 26.66 ($40/$1.50).

Currently, consumer staples represent around 11.15% of the S&P 500. Another defensive sector, utilities (NYSEARCA:XLU) which makes up just 3.65% of the S&P 500, also trades at a premium. The Utilities Select Sector SPDR ETF (XLU) owns 31 stocks involved in generating and distributing both electric and natural gas power.  XLU has gained 18.48% since the beginning of the year and has a P/E ratio of 16.7. 

Overstretched valuations alone are not necessarily a sell signal. But properly used in conjunction with other indicators, it most certainly raises cautionary red flags.
