Key Points
  • The Energy Select Sector SPDR fund is trading at its highest levels in nearly three years.
  • The basket of energy stocks is breaking out at the same time that crude oil prices are rising to their highest levels since November 2014.
  • The rally in energy stocks could continue despite the long-term trend, according to one trader.

A closely followed basket of energy stocks hit a nearly three-year high Thursday and could keep rising despite long-term market trends.

The Energy Select Sector SPDR exchange-traded fund — better known by its ticker symbol XLE — rose as high as $78.83 on Thursday. At that level, it's trading at its highest since June 3, 2015, when it topped out at $79.07.

Energy stocks are finally breaking out for several reasons, but the run-up in oil prices is supporting the sector in the near term. Brent crude oil on Thursday went above $80 a barrel for the first time since November 2014, fueled by geopolitical uncertainty after the Trump administration restored sanctions on major crude exporter Iran.

The XLE has now crossed two significant thresholds, according to Roberto Friedlander, head of energy trading at Seaport Global Securities.

First, the XLE topped January's high of $78.39 at the same time and U.S. crude are hitting 3½-year highs. Second, the fund is breaking above the upper Bollinger Band. The so-called Bollinger Bands represent a range that indicates when prices for an asset are either looking expensive or have potentially become undervalued.

Rising above the upper Bollinger band often sets up a sell-off that knocks the asset price back within the range. However, it's possible that history will not be a guide in today's market because investors are still not holding a lot of energy stocks, according to Friedlander.

"There are a lot of longer-term money managers still underweight energy as a whole," he said. "I think this could keep going for a while."

The XLE is now on pace for its 10th straight day of gains, a feat it has not accomplished since it notched a 10-day winning streak in July 2006. The fund is also on pace for its sixth straight week of advances, its longest week-to-week stretch since September.
