It's nice to see the Pentanet Limited (ASX:5GG) share price up 19% in a week. But that is minimal compensation for the share price under-performance over the last year. In fact, the price has declined 22% in a year, falling short of the returns you could get by investing in an index fund.

On a more encouraging note the company has added AU$25m to its market cap in just the last 7 days, so let's see if we can determine what's driven the one-year loss for shareholders.

Pentanet wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last year Pentanet saw its revenue grow by 118%. That's well above most other pre-profit companies. Given the revenue growth, the share price drop of 22% seems quite harsh. Our sympathies to shareholders who are now underwater. Prima facie, revenue growth like that should be a good thing, so it's worth checking whether losses have stabilized. Our brains have evolved to think in linear fashion, so there's value in learning to recognize exponential growth. We are, in some ways, simply the wisest of the monkeys.

A Different Perspective

While Pentanet shareholders are down 22% for the year, the market itself is up 9.1%. While the aim is to do better than that, it's worth recalling that even great long-term investments sometimes underperform for a year or more. It's worth noting that the last three months did the real damage, with a 28% decline. This probably signals that the business has recently disappointed shareholders - it will take time to win them back. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
