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. Unfortunately, these high risk investments often have little probability of ever paying off, and many investors pay a price to learn their lesson. 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 Cantaloupe (NASDAQ:CTLP). While this doesn't necessarily speak to whether it's undervalued, the profitability of the business is enough to warrant some appreciation - especially if its growing.

How Fast Is Cantaloupe Growing Its Earnings Per Share?

Investors and investment funds chase profits, and that means share prices tend rise with positive earnings per share (EPS) outcomes. Which is why EPS growth is looked upon so favourably. It's an outstanding feat for Cantaloupe to have grown EPS from US$0.00014 to US$0.16 in just one year. Even though that growth rate may not be repeated, that looks like a breakout improvement.

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. The good news is that Cantaloupe is growing revenues, and EBIT margins improved by 4.1 percentage points to 5.7%, over the last year. That's great to see, on both counts.

Are Cantaloupe 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.
