It is hard to get excited after looking at Aehr Test Systems' (NASDAQ:AEHR) recent performance, when its stock has declined 31% over the past month. But if you pay close attention, you might gather that its strong financials could mean that the stock could potentially see an increase in value in the long-term, given how markets usually reward companies with good financial health. Particularly, we will be paying attention to Aehr Test Systems' ROE today.

ROE or return on equity is a useful tool to assess how effectively a company can generate returns on the investment it received from its shareholders. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

How To Calculate Return On Equity?

ROE can be calculated by using the formula:

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

So, based on the above formula, the ROE for Aehr Test Systems is:

24% = US$29m ÷ US$122m (Based on the trailing twelve months to August 2024).

The 'return' is the profit over the last twelve months. Another way to think of that is that for every $1 worth of equity, the company was able to earn $0.24 in profit.

What Is The Relationship Between ROE And Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. Based on how much of its profits the company chooses to reinvest or "retain", we are then able to evaluate a company's future ability to generate profits. 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.
