Shares in small Australian nickel and cobalt explorer GME Resources jumped as much as 53 percent on Thursday, apparently driven by the similarity of its stock ticker code to US retail investor darling GameStop.
GME Resources stock closed up 13 percent at 8.5 Australian cents, or a gain of one cent on the day, giving up most of its gains of four cents in early trade, when it reached A$0.115 ($0.0878). It rose 14 percent on Wednesday.
"There are people buying the stock for shits and giggles, just because of the ticker symbol," said market analyst Kyle Rodda of brokerage IG Markets in Melbourne.
"It's all caught up in this GameStop dynamic," he said.
"It's got nothing to do with the company and entirely to do with this mad phenomenon that we're seeing at the moment where these Redditers looking to swarm into these stocks and play around with the market a little bit for their own amusement."
Shares of US videogame retailer GameStop have soared about 17-fold since January 12 as small investors, organising on social media, have piled in and forced professional short-sellers to abandon their positions with heavy losses.
A spokesman for GME Resources was not available for comment. However, Managing Director Peter Sullivan told the Sydney Morning Herald newspaper the surge caught him by surprise.
"When I opened my share tracking app and saw it was at 9.4 cents, I was stunned," he told the paper. "It just went bang, and I thought: 'Well, what's going on here? Is there something about my own company that I don't know?'"
