Here's Why We Think Protia (KOSDAQ:303360) Might Deserve Your Attention Today

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.

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 Protia (KOSDAQ:303360). 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 Protia 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. Therefore, there are plenty of investors who like to buy shares in companies that are growing EPS. It certainly is nice to see that Protia has managed to grow EPS by 24% per year over three years. If growth like this continues on into the future, then shareholders will have plenty to smile about.

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 music to the ears of Protia shareholders is that EBIT margins have grown from 2.5% to 19% in the last 12 months and revenues are on an upwards trend as well. Both of which are great metrics to check off for potential growth.
