The Globe and Mail reports in its Wednesday, July 5, edition that TD Securities recently produced a list of Canadian-listed exchange traded funds with the most exposure to artificial intelligence. The Globe's Rob Carrick writes that the funds were listed in various categories, including thematic ETFs and broad market ETFs. Among thematic ETFs, the funds mentioned by TD include: Horizons Robotics and Automation Index ETF; Evolve FANGMA Index ETF; Horizons Global Metaverse Index; Evolve Cloud Computing Index Fund; and BMO MSCI Next Gen Internet Innovation Index. Mr. Carrick says most of these funds are quite small, which means investors should keep an eye on trading volumes and bid-ask spreads. Wide spreads suggest you will pay a premium price to buy and you may have trouble selling at a competitive price if AI loses momentum as an investing theme. Broad-market ETFs mentioned by TD included the TD Global Technology Leaders Index ETF and Nasdaq 100 ETFs from BMO, Horizons, iShares and Invesco. While AI has the potential to become a powerful force in the economy, we are in the early stages of seeing which companies can participate in the sector profitably. Expect to see some AI stocks rise and fall.
