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 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.

If this kind of company isn't your style, you like companies that generate revenue, and even earn profits, then you may well be interested in Cabot (NYSE:CBT). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

Cabot's Improving Profits

In the last three years Cabot's earnings per share took off; so much so that it's a bit disingenuous to use these figures to try and deduce long term estimates. Thus, it makes sense to focus on more recent growth rates, instead. Impressively, Cabot's EPS catapulted from US$2.51 to US$5.36, over the last year. It's not often a company can achieve year-on-year growth of 114%.

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. It seems Cabot is pretty stable, since revenue and EBIT margins are pretty flat year on year. While this doesn't ring alarm bells, it may not meet the expectations of growth-minded investors.
