In this article, I’ll talk about one of the best Canadian stocks you can buy right now that Bay Street analysts expect to more than double in 2023. Bay Street analysts expect this Canadian stock to double in 2023 If you don’t know it already, Ballard Power Systems (TSX:BLDP) is a Burnaby-headquartered company with a market cap of $2.4 billion. After delivering an outstanding return of more than 800% in 2019 and 2020 combined, this Canadian stock tanked by 78% in the next two years, as its weak sales in China and Europe continued to hurt investors’ sentiments.

According to Bay Street analysts’ consensus data, Ballard Power’s share prices could reach $17.03 per share in the next 12 months, reflecting an outstanding 111% upside potential from its current market price. What could help it soar in 2023 and beyond? Whether you’re picking a stock yourself or based on analysts’ views, you must always pay attention to the stock’s ongoing financial growth trends and future growth prospects. So, now, let me give you some key reasons Ballard Power Systems could be a great Canadian stock to consider in 2023. Ballard Power Systems has more than four decades of experience designing, developing, and manufacturing proton exchange membrane fuel cells. Such fuel cells are mainly used in a variety of electric mobility solutions like buses, trucks, trains, and marine vessels. The company has a geographically well-diversified business model. Based on its 2021 financial figures, Ballard Power made nearly 41% of its total revenue from Europe, 37% from China, and the remaining from North America and other countries. While Ballard Power’s revenues have declined in the last couple of quarters, analysts expect its sales to grow by around 22% in 2023 to US$108.8 million. After increasing its focus on product standardization in recent years, the company expects to achieve increased manufacturing and supply chain efficiency along with economies of scale in the coming years. Moreover, the demand for clean energy is continuing to surge, which could boost the demand for Ballard’s fuel cells going forward and speed up its financial growth. These could be some of the key reasons why BLDP stock could help you get outstanding returns on investments if you buy it now.
