Greed is good — especially when the stakes are low.

MarketWatch’s Virtual Stock Exchange, which got a long-awaited revamp this week, lets you test-drive your stock-market savvy without the perils of losing your life savings. (MarketWatch and Moneyish share a common publisher, Dow Jones Media Group.)

The VSE simulator lets you build a virtual portfolio and trade stocks while reacting to the market’s whims in real time. It’s customizable, so you can set a starting budget and create your own stock watchlist — and social, so you can talk trash or trade strategy with your friends, family or coworkers. If you’re an educator, your students can get hands-on trading experience. And no one loses any actual money.
