Hi all, am a long term stockholder of GXY/Allkem and have made good and bad decision along the last 8-9 years with this stock but obviously have profited substantially. Not being familiar with the AUS stock- and derivatives market I have the following question:
Is there a market for derivatives on the stock? If yes, which one? How liquid is it and have you yourself made experience with short selling calls (or similar instruments) on the stock. Thanks
