Shares in Sparc Tech rose by 21.43 per cent over last week’s trading days, with its valuation having doubled over the past year to $40 million.
The green hydrogen innovator last week announced it had obtained a dual listing on the OTCQB Venture Market in the United States, expanding its pool of potential investors.
The OTCQB Venture Market is for early-stage and developing US and international companies, and Sparc Tech will continue to use the Australian Stock Exchange as its primary exchange.
“Our decision to uplist on the OTCQB Venture Market is a result of strong interest from North American retail and high net wealth investors, which has been particularly evident over the past couple of months,” Sparc Tech managing director Nick O’Loughlin said.
“A listing on OTCQB aligns Sparc with a number of our international graphene peers and provides North American investors with the ability to trade Sparc shares in US dollars in a local timezone.”
In the Losers list was 1414 Degrees, which saw shares drop by 22.22 per cent over the trading week despite announcing a new partnership with a manufacturer of drones for the Ukrainian defence force.
Overall, for the year 1414 Degrees is one of the top performers, with shares up 268.42 per cent over the year to date.
And Altitude Minerals also fell by 23.08 per cent, making it the biggest Loser of the week.
