Investors are often guided by the idea of discovering 'the next big thing', even if that means buying 'story stocks' without any revenue, let alone profit. But as Peter Lynch said in One Up On Wall Street, 'Long shots almost never pay off.' Loss making companies can act like a sponge for capital - so investors should be cautious that they're not throwing good money after bad.

Despite being in the age of tech-stock blue-sky investing, many investors still adopt a more traditional strategy; buying shares in profitable companies like Powermatic Data Systems (SGX:BCY). 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.

How Quickly Is Powermatic Data Systems Increasing Earnings Per Share?

Careful consideration of revenue growth and earnings before interest and taxation (EBIT) margins can help inform a view on the sustainability of the recent profit growth.
