The benchmark Energy Select Sector SPDR (NYSE: XLE ) fell to its lowest levels of 2014 on Friday and is now down more than 16 percent this year. The stock market hit a speed bump this week as plunging crude oil prices continued to pressure the energy sector. This deflation in energy stocks finally made a dent in the broad market as well, with the SPDR S&P 500 ETF (NYSE: SPY ) dropping more than 2 percent this week.
