HEU follows top Canadian Energy players like Suncor and Canadian Natural Resources with some smaller ones on a 2x leveraged basis.
NRGU follows big US Oil players like Exxon, EOG and so forth . It follows the 10 biggest US oil companies at 10% per stock on a 3x leveraged basis.
Both are good plays for 2020 that use a leveraged return profile.
It is important to be patient. A quick spike in oil may not always equate to some epic rise in energy stocks. Similar to Gold stocks, it took at-least 4-5 weeks of elevated Gold prices for the mining sector to take off - the same will be true for the energy sector.
