Tonight, the highly anticipated Iowa presidential caucus will take place. A victory by Senator Bernie Sanders of Vermont or Senator Elizabeth Warren of Massachusetts will likely continue to pressure many of the leading healthcare stocks. Recently, Senator Bernie Sanders has taken a lead in the polls and this has already caused a two week decline in the Health Care Select Sector SPDR Fund (NYSEARCA:XLV).

This leading ETF peaked on January 21, 2020 at $105.08 a share, exactly as Senator Sanders solidified his current lead. All traders and investors will now be following tonight’s contest. There are only 41 delegates up for grabs tonight, but it does set the tone for the politicians as they move on to the New Hampshire primary on Feb. 11, 2020.
