The brand new YoWorld Stock Market is now available. Keep reading for more information on how to use it!
Head to the Bank or click the Stocks tab:

The Stock Market looks like this:

The ticker shows each company's change from the last 24 hours.
Use the Market tab to see all available stocks, and the Portfolio tab to see what you own.

The Market tab
The Market tab shows you all of the available stocks. From this tab, you can see a stock's current value, and how how much it's changed in the last 6 hours. Click on any heading (ID, Business, Current Value, Change, Change %) to sort stocks by that heading!

Click a stock to find more details about it! You'll be able to see a handy graph with its historical values to help you choose which stocks you want to buy. Check on a company's last hour, 6 hours, 1 day, 5 days. or 1 month (once they've been around long enough) to make better investments!

The Portfolio tab
The Portfolio tab is similar to the Market tab, but it only includes stocks that you already own. You can own up to 100 shares of each stock at a time. It will also show you the current profit that you would make if you sold your stocks right then.

But remember! There is 0.25% transaction fee per sale of shares (a minimum of 10 YoCoins). The "Total Value" column is before the fee, but the "Total Earn" value (next to the Sell button) is after the fee. Make sure that Total Earn is more than you paid for your shares to profit!
The idea is to buy shares when the value is low, then sell when the value is high! Any stocks you buy come with a risk, because stocks can lose value too... Decide how much you want to risk, and you could make lots of YoCoins if you're a savvy investor!
