Utilities are one of the most vulnerable sectors to rising interest rates. Utilities have been on a notable uptrend in the last few weeks. In fact, utilities (IDU) gained momentum after the Fed delivered a rate hike in June. Currently, the Utilities Select Sector SPDR ETF (XLU) is trading 3% above its 50-day and 200-day moving average levels. The premium against both of these support levels indicates strength in XLU. The moving average level around $51.5 will likely act as a support for XLU in the short term. XLU closed at $53.0 on August 10.
