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. Sometimes these stories can cloud the minds of investors, leading them to invest with their emotions rather than on the merit of good company fundamentals. A loss-making company is yet to prove itself with profit, and eventually the inflow of external capital may dry up.
So if this idea of high risk and high reward doesn’t suit, you might be more interested in profitable, growing companies, like Japan Insulation (TSE:5368). Even if this company is fairly valued by the market, investors would agree that generating consistent profits will continue to provide Japan Insulation with the means to add long-term value to shareholders.

Japan Insulation’s Earnings Per Share Are Growing
The market is a voting machine in the short term, but a weighing machine in the long term, so you’d expect share price to follow earnings per share (EPS) outcomes eventually. That makes EPS growth an attractive quality for any company. We can see that in the last three years Japan Insulation grew its EPS by 13% 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 music to the ears of Japan Insulation shareholders is that EBIT margins have grown from 8.3% to 11% 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.
