Q: Hi, My current exposure to the health care sector is less than 2%. I am considering increasing my position to approximately 5% by means of etf (I currently own GUD and GILD approx 1% each). I am considering XLV or IBB for etfs. Which of these (or) any other etf you would recommend? I noted that IBB seems more volatile than XLV when I compared them..I was wondering why?
