The excitement of investing in a company that can reverse its fortunes is a big draw for some speculators, so even companies that have no revenue, no profit, and a record of falling short, can manage to find investors. But the reality is that when a company loses money each year, for long enough, its investors will usually take their share of those losses. Loss-making companies are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

So if this idea of high risk and high reward doesn't suit, you might be more interested in profitable, growing companies, like Park-Ohio Holdings (NASDAQ:PKOH). Now this is not to say that the company presents the best investment opportunity around, but profitability is a key component to success in business.
