For beginners, it can seem like a good idea (and an exciting prospect) to buy a company that tells a good story to investors, even if it currently lacks a track record of revenue and profit. 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 can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

In contrast to all that, many investors prefer to focus on companies like Descartes Systems Group (TSE:DSG), which has not only revenues, but also profits. Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Descartes Systems Group with the means to add long-term value to shareholders.
