What Swelect Energy Systems Limited's (NSE:SWELECTES) 25% Share Price Gain Is Not Telling You

Swelect Energy Systems Limited (NSE:SWELECTES) shares have continued their recent momentum with a 25% gain in the last month alone. The annual gain comes to 286% following the latest surge, making investors sit up and take notice.

Following the firm bounce in price, Swelect Energy Systems' price-to-earnings (or "P/E") ratio of 66x might make it look like a strong sell right now compared to the market in India, where around half of the companies have P/E ratios below 30x and even P/E's below 17x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

For example, consider that Swelect Energy Systems' financial performance has been poor lately as its earnings have been in decline. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/E from collapsing. If not, then existing shareholders may be quite nervous about the viability of the share price.

What Are Growth Metrics Telling Us About The High P/E?

In order to justify its P/E ratio, Swelect Energy Systems would need to produce outstanding growth well in excess of the market.

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 16%. However, a few very strong years before that means that it was still able to grow EPS by an impressive 64% in total over the last three years. So we can start by confirming that the company has generally done a very good job of growing earnings over that time, even though it had some hiccups along the way.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 24% shows it's noticeably less attractive on an annualised basis.

With this information, we find it concerning that Swelect Energy Systems is trading at a P/E higher than the market. Apparently many investors in the company are way more bullish than recent times would indicate and aren't willing to let go of their stock at any price. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From Swelect Energy Systems' P/E?

The strong share price surge has got Swelect Energy Systems' P/E rushing to great heights as well. It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

Our examination of Swelect Energy Systems revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
