Shareholders in Castellum (STO:CAST) are in the red if they invested five years ago

Ideally, your overall portfolio should beat the market average. But every investor is virtually certain to have both over-performing and under-performing stocks. So we wouldn't blame long term Castellum AB (publ) (STO:CAST) shareholders for doubting their decision to hold, with the stock down 51% over a half decade.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

We know that Castellum has been profitable in the past. 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.

Revenue is actually up 15% over the time period. So it seems one might have to take closer look at the fundamentals to understand why the share price languishes. After all, there may be an opportunity.

What About The Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between Castellum's total shareholder return (TSR) and its share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Castellum's TSR of was a loss of 34% for the 5 years. That wasn't as bad as its share price return, because it has paid dividends.

A Different Perspective

While the broader market gained around 17% in the last year, Castellum shareholders lost 3.9%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. However, the loss over the last year isn't as bad as the 6% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. 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.
