More gains could be on the way for the $337.4 million CGW, which tracks the S&P Global Water NR Index.

“CGW looks great on the daily chart, as it has been tightening up the past three weeks while holding the rising 50-day MA. This week’s action is very tight and could possibly lead to a breakout next week,” said Deron Wagner of Morpheus Trading Group.

Although CGW currently labors slightly below its 50-day moving average, the ETF is trading 8% above its 200-day line.

CGW also offers ample developed market exposure. After the 37.8% allocation to the U.S., CGW devotes a combine 34% of its weight to the U.K., France and Switzerland.
