Data Storage (NASDAQ:DTST) has had a great run on the share market with its stock up by a significant 11% over the last week. However, we decided to pay attention to the company's fundamentals which don't appear to give a clear sign about the company's financial health. In this article, we decided to focus on Data Storage's ROE.

Return on equity or ROE is an important factor to be considered by a shareholder because it tells them how effectively their capital is being reinvested. In other words, it is a profitability ratio which measures the rate of return on the capital provided by the company's shareholders.

How Do You Calculate Return On Equity?

The formula for ROE is:

Return on Equity = Net Profit (from continuing operations) ÷ Shareholders' Equity

So, based on the above formula, the ROE for Data Storage is:

3.0% = US$610k ÷ US$20m (Based on the trailing twelve months to March 2024).

The 'return' is the yearly profit. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.03 in profit.

What Has ROE Got To Do With Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. We now need to evaluate how much profit the company reinvests or "retains" for future growth which then gives us an idea about the growth potential of the company. Assuming all else is equal, companies that have both a higher return on equity and higher profit retention are usually the ones that have a higher growth rate when compared to companies that don't have the same features.

A Side By Side comparison of Data Storage's Earnings Growth And 3.0% ROE

It is hard to argue that Data Storage's ROE is much good in and of itself. Even compared to the average industry ROE of 12%, the company's ROE is quite dismal. Given the circumstances, the significant decline in net income by 50% seen by Data Storage over the last five years is not surprising. However, there could also be other factors causing the earnings to decline. For instance, the company has a very high payout ratio, or is faced with competitive pressures.

So, as a next step, we compared Data Storage's performance against the industry and were disappointed to discover that while the company has been shrinking its earnings, the industry has been growing its earnings at a rate of 8.8% over the last few years.

Earnings growth is a huge factor in stock valuation. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. Doing so will help them establish if the stock's future looks promising or ominous.

Is Data Storage Efficiently Re-investing Its Profits?

Data Storage doesn't pay any regular dividends, meaning that potentially all of its profits are being reinvested in the business, which doesn't explain why the company's earnings have shrunk if it is retaining all of its profits. It looks like there might be some other reasons to explain the lack in that respect. For example, the business could be in decline.

Conclusion

In total, we're a bit ambivalent about Data Storage's performance. While the company does have a high rate of profit retention, its low rate of return is probably hampering its earnings growth.
