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. 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 are always racing against time to reach financial sustainability, so investors in these companies may be taking on more risk than they should.

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 Capital Power (TSE:CPX). While profit isn't the sole metric that should be considered when investing, it's worth recognising businesses that can consistently produce it.

How Quickly Is Capital Power Increasing Earnings Per Share?

If you believe that markets are even vaguely efficient, then over the long term you'd expect a company's share price to follow its earnings per share (EPS) outcomes. That makes EPS growth an attractive quality for any company. Recognition must be given to the that Capital Power has grown EPS by 41% per year, over the last three years. While that sort of growth rate isn't sustainable for long, it certainly catches the eye of prospective investors.

One way to double-check a company's growth is to look at how its revenue, and earnings before interest and tax (EBIT) margins are changing. Capital Power shareholders can take confidence from the fact that EBIT margins are up from 13% to 26%, and revenue is growing. Ticking those two boxes is a good sign of growth, in our book.

Are Capital Power Insiders Aligned With All Shareholders?

Investors are always searching for a vote of confidence in the companies they hold and insider buying is one of the key indicators for optimism on the market. This view is based on the possibility that stock purchases signal bullishness on behalf of the buyer. However, insiders are sometimes wrong, and we don't know the exact thinking behind their acquisitions.

While Capital Power insiders did net CA$2.1m selling stock over the last year, they invested CA$3.1m, a much higher figure. You could argue that level of buying implies genuine confidence in the business. It is also worth noting that it was Senior VP & Chief Commercial Officer Bryan DeNeve who made the biggest single purchase, worth CA$2.1m, paying CA$44.17 per share.
