Most readers would already be aware that Quanex Building Products' (NYSE:NX) stock increased significantly by 14% over the past month. Since the market usually pay for a company's long-term fundamentals, we decided to study the company's key performance indicators to see if they could be influencing the market. Particularly, we will be paying attention to Quanex Building Products' ROE today.

Return on Equity or ROE is a test of how effectively a company is growing its value and managing investors' money. In simpler terms, it measures the profitability of a company in relation to shareholder's equity.

How Do You Calculate Return On Equity?

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 Quanex Building Products is:

13% = US$74m ÷ US$594m (Based on the trailing twelve months to July 2024).

The 'return' is the amount earned after tax over the last twelve months. That means that for every $1 worth of shareholders' equity, the company generated $0.13 in profit.

Why Is ROE Important For Earnings Growth?

So far, we've learned that ROE is a measure of a company's profitability. 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 Quanex Building Products' Earnings Growth And 13% ROE

At first glance, Quanex Building Products seems to have a decent ROE. Yet, the fact that the company's ROE is lower than the industry average of 19% does temper our expectations. However, we are pleased to see the impressive 41% net income growth reported by Quanex Building Products over the past five years. We believe that there might be other aspects that are positively influencing the company's earnings growth. For example, it is possible that the company's management has made some good strategic decisions, or that the company has a low payout ratio. However, not to forget, the company does have a decent ROE to begin with, just that it is lower than the industry average. So this also does lend some color to the high earnings growth seen by the company.

Next, on comparing with the industry net income growth, we found that Quanex Building Products' growth is quite high when compared to the industry average growth of 18% in the same period, which is great to see.

Earnings growth is an important metric to consider when valuing a stock. What investors need to determine next is if the expected earnings growth, or the lack of it, is already built into the share price. This then helps them determine if the stock is placed for a bright or bleak future. What is NX worth today?
