Once a scenario starts, open the stocks page. Find oil refinery cities to invest in (for example, Marseilles or New Orleans). Notice that each should be worth $100 a share, with 49,000 shares available. Purchase as much refinery stock as possible with your starting capital of $4,000,000. The stock price should jump over $10. Quickly sell that stock. The stock prices will then drop back down to $100. Repeat this process until the stock price stops jumping to make an easy early profit.
