Like a puppy chasing its tail, some new investors often chase 'the next big thing', even if that means buying 'story stocks' without revenue, let alone profit. But as Warren Buffett has mused, 'If you've been playing poker for half an hour and you still don't know who the patsy is, you're the patsy.' When they buy such story stocks, investors are all too often the patsy.

In contrast to all that, I prefer to spend time on companies like National Aluminium (NSE:NATIONALUM), which has not only revenues, but also profits. While profit is not necessarily a social good, it's easy to admire a business that can consistently produce it. In comparison, loss making companies act like a sponge for capital - but unlike such a sponge they do not always produce something when squeezed.

As one of my mentors once told me, share price follows earnings per share (EPS). Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. Over the last three years, National Aluminium has grown EPS by 16% per year. That's a good rate of growth, if it can be sustained.

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. The good news is that National Aluminium is growing revenues, and EBIT margins improved by 20.4 percentage points to 22%, over the last year. Ticking those two boxes is a good sign of growth, in my book.

While it's always good to see growing profits, you should always remember that a weak balance sheet could come back to bite. So check National Aluminium's balance sheet strength, before getting too excited.

I like company leaders to have some skin in the game, so to speak, because it increases alignment of incentives between the people running the business, and its true owners. So it is good to see that National Aluminium insiders have a significant amount of capital invested in the stock. To be specific, they have ₹2.5b worth of shares. That shows significant buy-in, and may indicate conviction in the business strategy. Despite being just 1.4% of the company, the value of that investment is enough to show insiders have plenty riding on the venture.

It's good to see that insiders are invested in the company, but are remuneration levels reasonable? A brief analysis of the CEO compensation suggests they are. I discovered that the median total compensation for the CEOs of companies like National Aluminium with market caps between ₹150b and ₹481b is about ₹44m.

The National Aluminium CEO received total compensation of just ₹4.9m in the year to . That's clearly well below average, so at a glance, that arrangement seems generous to shareholders, and points to a modest remuneration culture. CEO compensation is hardly the most important aspect of a company to consider, but when its reasonable that does give me a little more confidence that leadership are looking out for shareholder interests. It can also be a sign of a culture of integrity, in a broader sense.

One positive for National Aluminium is that it is growing EPS. That's nice to see. Earnings growth might be the main game for National Aluminium, but the fun does not stop there. With a meaningful level of insider ownership, and reasonable CEO pay, a reasonable mind might conclude that this is one stock worth watching. You should always think about risks though.
