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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. 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 Tate & Lyle (LON:TATE). 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.
