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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. A loss-making company is yet to prove itself with profit, and eventually the inflow of external capital may dry up.

In contrast to all that, many investors prefer to focus on companies like TransAlta (TSE:TA), which has not only revenues, but also profits. While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

TransAlta's Improving Profits

TransAlta has undergone a massive growth in earnings per share over the last three years. So much so that this three year growth rate wouldn't be a fair assessment of the company's future. So it would be better to isolate the growth rate over the last year for our analysis. Impressively, TransAlta's EPS catapulted from CA$0.95 to CA$1.90, over the last year. Year on year growth of 100% is certainly a sight to behold.

Top-line growth is a great indicator that growth is sustainable, and combined with a high earnings before interest and taxation (EBIT) margin, it's a great way for a company to maintain a competitive advantage in the market. We note that while EBIT margins have improved from 23% to 32%, the company has actually reported a fall in revenue by 9.4%. While not disastrous, these figures could be better.

Are TransAlta Insiders Aligned With All Shareholders?

It's pleasing to see company leaders with putting their money on the line, so to speak, because it increases alignment of incentives between the people running the business, and its true owners. TransAlta followers will find comfort in knowing that insiders have a significant amount of capital that aligns their best interests with the wider shareholder group. Indeed, they hold CA$17m worth of its stock. That's a lot of money, and no small incentive to work hard. While their ownership only accounts for 0.4%, this is still a considerable amount at stake to encourage the business to maintain a strategy that will deliver value to shareholders.

Does TransAlta Deserve A Spot On Your Watchlist?

TransAlta's earnings have taken off in quite an impressive fashion. That EPS growth certainly is attention grabbing, and the large insider ownership only serves to further stoke our interest. At times fast EPS growth is a sign the business has reached an inflection point, so there's a potential opportunity to be had here. So based on this quick analysis, we do think it's worth considering TransAlta for a spot on your watchlist. Still, you should learn about the 3 warning signs we've spotted with TransAlta (including 1 which is potentially serious).
