Although it’s not as large as the US biotech industry, the Canadian biotech market is still making a name for itself on the global investment stage in terms of size and opportunities.
In recent years, the biotech sector worldwide has become a “real industry” that brought “spectacular” returns for mid-cap companies in 2020, according to Jessica Chutter, managing director and chairman of biotechnology investment banking with Morgan Stanley (NYSE:MS).
Much of the growth in biotech is attributable to technology advancements in drug research and development, said Chutter, who was speaking at a virtual event hosted by the Globe and Mail.
Also speaking during the event, Brian Bloom, co-founder, chairman and CEO of Toronto-based investment firm Bloom Burton & Co., said Canada accounts for approximately 3 percent of the biotech sector’s global market capitalization. Bloom noted that Canadian biotech companies raised an impressive US$3.2 billion in financing for 2020. That’s out of more than US$110 billion globally.
Unsurprisingly, many top Canadian biotech stocks have performed well against that backdrop, and have continued that solid performance into 2021 — in fact, analysts expect this year to be another period of stellar growth for the biotech industry, including in Canada.
