Hi David,
In theory the answer is yes but in reality, the ETFs are more of a derivative of the underlying stock prices, for example the commonly referenced URNM ETF which is traded on the ASX is made up of 42 stocks, with the 5 largest holdings being Cameco Corp, NAC Kazatomprom, Sprott Physical Uranium, Energy Fuels Canada and Uranium Energy Corp, a very diverse group of companies.
Traders who are looking for shorts are generally very stock specific with Boss Energy (BOE) and Paladin (PDN) the two most shorted stocks on the ASX at present with their operational issues driving these positions as much as their exposure to uranium which itself is mildly higher in 2025, while the URNM ETF has almost doubled from its April low.
Hence our answer is no, the volumes are high because the ETF/sector has been volatile through 2024/5.
