KOL was one of a small number of ETFs to hit a 52-week high yesterday and while the ETF’s run higher has been mostly unabated this year, some traders see KOL close to encountering its first significant resistance area.

“VanEck Vectors Coal ETF’s run has been as consistent as they come, as the nine-month trading channel clearly depicts,” according to an Instinet note posted by Ben Levisohn of Barron’s. “This makes the ETF extended from a daily chart perspective. But the move is barely noticeable from a very long-term view point.”

Looking ahead, the coal industry’s good fortune is ultimately tied to restrictions on China’s output, UBS Group AG said, also raising its coking-coal forecasts for this year and the next.

“So, while standing in front of this trend has proven fruitless thus far in 2016, VanEck Vectors Coal ETF is now approaching the first real resistance zone. The 12 – 15 zone is book ended by a five year downtrend line and the 2013 lows. If VanEck Vectors Coal ETF is going to slow down any time soon, that area seems like a logical place for it to happen,” according to the Instinet note posted by Barron’s.
