"I posed the question earlier, if the stock is such a good buy why don't the US investors buy on the ASX like we are being asked to do on the NASDAQ with this change."
As an ordinary dad and mom investor, I know Microsoft, Amazon, Tesla are good companies but I am not freely to invest via my broker (e. NAB, ComSec), I guess there are hurdles/thresholds you need to fulfill investor such as a minimal amount. However if they are listed in ASX with their full shares available I will definitely buy their shares.
