Penguin Solutions, Inc. (NASDAQ:PENG) shareholders should be happy to see the share price up 14% in the last month. But that cannot eclipse the less-than-impressive returns over the last three years. After all, the share price is down 40% in the last three years, significantly under-performing the market.

While the last three years has been tough for Penguin Solutions shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

Penguin Solutions became profitable within the last five years. However, it made a loss in the last twelve months, suggesting profit may be an unreliable metric at this stage. Other metrics may better explain the share price move.

Arguably the revenue decline of 9.4% per year has people thinking Penguin Solutions is shrinking. And that's not surprising, since it seems unlikely that EPS growth can continue for long in the absence of revenue growth.

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

A Different Perspective

Penguin Solutions provided a TSR of 5.9% over the last twelve months. Unfortunately this falls short of the market return. On the bright side, that's still a gain, and it's actually better than the average return of 2% over half a decade This could indicate that the company is winning over new investors, as it pursues its strategy. 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. Take risks, for example - Penguin Solutions has 2 warning signs (and 1 which shouldn't be ignored) we think you should know about.
