Saia (NASDAQ:SAIA) has had a great run on the share market with its stock up by a significant 15% over the last three months. Given that the market rewards strong financials in the long-term, we wonder if that is the case in this instance. Particularly, we will be paying attention to Saia's ROE today.

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 simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Is ROE Calculated?

Return on equity 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 Saia is:

17% = US$375m ÷ US$2.2b (Based on the trailing twelve months to September 2024).

The 'return' refers to a company's earnings over the last year. One way to conceptualize this is that for each $1 of shareholders' capital it has, the company made $0.17 in profit.

What Has ROE Got To Do With Earnings Growth?

Thus far, we have learned that ROE measures how efficiently a company is generating its profits. 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.
