Strong company. This is the main company for Moomoo, the popular brokerage that is marketing heavily here in Canada in an attempt to grow.
If I am being completely honest, if I wanted exposure to a brokerage I'd likely choose Interactive Brokers (IBKR). It is a better operated broker and is also located in the United States. This is a bit biased in my regard, but I do not like exposure to companies operating primarily in China, especially a financial company which is prone to regulatory changes.
I think it's a great company, if you're comfortable with that exposure. It is trading at only 13x forward earnings, nearly half of something like IBKR. But, that China exposure is likely going to be the reasoning for that.
