Marin Katusa, former chief investment strategist at Casey Research and recent founder of Katusa Research, is very well versed in the energy sector. It's thus no surprise that those interested in the oil, gas and uranium spaces made sure to listen in on his keynote presentation at the recent Canadian Investor Conference. Here's a look at what he said about uranium market trends during his talk, and how he believes investors can use those trends to hone in on good companies to invest in. Focus on North America… Katusa told investors that when looking at uranium companies, the two areas they really need to focus on are Canada and the US. "Do you really think that a junior mining company in Canada has a chance in Africa or in Russia, where you compete with the Chinese and the Russians who don't follow the rules or laws that the Canadian or American securities rules follow? Not a chance," he quipped. Looking at what North American uranium companies have going on, Katusa said that the "Athabasca Basin is all about 'grade is king,' and the Southwest US is all about low-cost in-situ recovery (ISR)." One tip he gave is to keep an eye on reclamation costs when it comes to ISR. …but don't forget RLI In terms of producers, Katusa believes it's also important to keep an eye on reserve life index (RLI), which provides a measurement of the life span of a company's assets. In a report on his website, he states that RLI can be calculated by "look[ing] at total reserves divided by nameplate capacity." Explaining further, Katusa said, "when you are invested in a company and they bring something into production, and you are depleting your reserves in a low market and you hedge yourself, you have zero upside. That is why I have been saying for years to stay away from these hedge producers in a bad market." He added, "why be hedged in an underfeeding market where you are depressed? I think it is the stupidest thing that all of these producers have been doing."
