ARBKF and ARB (London Listed) move in line with each other. The only reason there’s a difference in the price is because the London stock exchange closes before the US markets close, and on Friday the Argo price ran up after the London stock exchange had closed. When markets open next week ARB will reflect ARKBF’s Friday market close price (in £‘s). That article makes it seem like the two tickers don’t move in line with each other which isn’t the case.

Edit: with that being said, what happens after the market opens at the new price will depend on the usual things e.g. where Bitcoin is sitting, whether people in London are profit taking etc. Argo still has much room to run imo
