The Wall Street Game
I have always found the stock market more interesting when an idea can be tested rather than simply discussed.
That is why I built the Wall Street Game. The idea is simple. Every player begins with $100 million in game money, but the share prices are real. You can buy and sell stocks, follow how your decisions develop and see what would have happened—without risking any actual money. There are many applications where you can make “paper“ trading, this app has three important differentiators:
- You don’t need an actual account - we’re all for privacy here in the EU, just enter a passkey and remember it. That’s it. no email no address no phone numbers.
- Every one starts at 100 million. So dollar per dollar we can compare which strategy is the best - all of you great investors out there - lets see what you can do.
- Everyone can see the leaderboard which accounts are doing better then the others - if its one of my experiments you can read a post about what strategy I used if if someone else’s just see how it does and what stocks he bought.
For me, the most useful part is the freedom to experiment. I can try one way of investing, follow a completely different idea elsewhere and then compare the results over time. Instead of saying that a particular approach should work, I can put it into the game and watch what actually happens.
I have developed several potential portfolios, each of which I will discuss in more detail—including why I made certain decisions. Some are deliberately simple: I choose a few stocks that I think may perform well, buy them and see what happens. Others are more systematic, such as evaluating the market each week and selecting stocks using mathematical analysis rather than instinct alone.
It also makes market decisions more honest. Looking backwards, it is always easy to explain why a stock rose or fell. The game asks you to make the decision first. Once it has been recorded, the market provides the answer.
Of course, it is still a game. It is not financial advice, and success with imaginary money does not guarantee success with real money. But it is a useful place to learn, test ideas and sometimes discover that the market behaves very differently from the way you expected and as always have some fun doing it.
