As you know the GameStop stock has been surging. Its ticker is GME. Interestingly enough, the same ticker belongs to GME Resources Ltd.. GME Resources is based in Australia. Since Wednesday, GME Resources popped over 80% and then dropped to a little higher than what it had been trading at on the beginning of Wednesday. This happened even though they trade on different security exchanges.

It might be wise to double check what securities exchange your stock is on before you purchase.
