Weight loss drugs have drawn investor interest and shaken up other sectors in the past year or so.
Novo Nordisk and Eli Lilly were two early winners of this trend, as their drugs dominate the weight loss drug market.
Yuri Khodjamirian, fund manager at Tema ETFs, said both companies are a "very powerful duopoly."
They're a lot more risky than the bigger ones who already have drugs on the market," Khodjamirian said.
Tema ETFs offers actively managed exchange-traded funds, with a focus on health care and life sciences.
