Should Weakness in Planoptik AG's (ETR:P4O) Stock Be Seen As A Sign That Market Will Correct The Share Price Given Decent Financials?

It is hard to get excited after looking at Planoptik's (ETR:P4O) recent performance, when its stock has declined 13% over the past month. But if you pay close attention, you might find that its key financial indicators look quite decent, which could mean that the stock could potentially rise in the long-term given how markets usually reward more resilient long-term fundamentals. Specifically, we decided to study Planoptik's ROE in this article.

Return on equity or ROE is a key measure used to assess how efficiently a company's management is utilizing the company's capital. Simply put, it is used to assess the profitability of a company in relation to its equity capital.

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 Planoptik is:

5.5% = €700k ÷ €13m (Based on the trailing twelve months to December 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 €0.05 in profit.

Why Is ROE Important For Earnings Growth?

We have already established that ROE serves as an efficient profit-generating gauge for a company's future earnings. Depending on how much of these profits the company reinvests or "retains", and how effectively it does so, we are then able to assess a company’s earnings growth potential. Generally speaking, other things being equal, firms with a high return on equity and profit retention, have a higher growth rate than firms that don’t share these attributes.

Planoptik's Earnings Growth And 5.5% ROE

When you first look at it, Planoptik's ROE doesn't look that attractive. Next, when compared to the average industry ROE of 14%, the company's ROE leaves us feeling even less enthusiastic. Despite this, surprisingly, Planoptik saw an exceptional 35% net income growth over the past five years. Therefore, there could be other reasons behind this growth. For instance, the company has a low payout ratio or is being managed efficiently.

Next, on comparing with the industry net income growth, we found that Planoptik's growth is quite high when compared to the industry average growth of 28% in the same period, which is great to see.

Earnings growth is an important metric to consider when valuing a stock. The investor should try to establish if the expected growth or decline in earnings, whichever the case may be, is priced in. This then helps them determine if the stock is placed for a bright or bleak future. One good indicator of expected earnings growth is the P/E ratio which determines the price the market is willing to pay for a stock based on its earnings prospects. So, you may want to check if Planoptik is trading on a high P/E or a low P/E, relative to its industry.

Is Planoptik Efficiently Re-investing Its Profits?

Planoptik doesn't pay any regular dividends to its shareholders, meaning that the company has been reinvesting all of its profits into the business. This is likely what's driving the high earnings growth number discussed above.

Summary

On the whole, we do feel that Planoptik has some positive attributes. Even in spite of the low rate of return, the company has posted impressive earnings growth as a result of reinvesting heavily into its business. While we won't completely dismiss the company, what we would do, is try to ascertain how risky the business is to make a more informed decision around the company.
