Tesla is the most-traded stock in week two of our global challenge

Now we're about half-way through, more than 100,000 moomoo users are competing in our global paper-trading challenge.

It's a huge number, and there's thousands of Australians among them.

But we're not keeping up our strong performance from week one.

When we look at the entrants from each of the competing seven nations, Asia has taken all top three spots, with Malaysia, Singapore and Hong Kong in the lead.

To note, 67.4% of Malaysian entrants are recording positive returns in the challenge!

And that means Australia has been bumped from last week's number two rank into the bottom four. (Just as Japan was dethroned from its leading position.)

But we're only half-way through. So in a few days we'll see how the nations have performed for week three, and maybe the Aussies will regain some lost ground. Remember, there's US$20,000 on offer every week of the five-week challenge, which means you can start anytime and still win.

The leaderboard shows the global leading entrant in the challenge has made 638% return on their initial virtual funds in the past two and a half weeks – with the top 10 all above 430% in returns. The Australian leader is up 148% in returns.

(For the weekly tally, keeping in mind we're only half way through week three, the global leader has made a 51% gain.)

Sign up and get involved. You've got literally nothing to lose and potentially a lot to gain. Even if you don't win, it's the most engaging way to sharpen up your investing skills.
