What Orient Green Power Company Limited's (NSE:GREENPOWER) 30% Share Price Gain Is Not Telling You

Orient Green Power Company Limited (NSE:GREENPOWER) shares have had a really impressive month, gaining 30% after a shaky period beforehand. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 28% in the last twelve months.

Since its price has surged higher, Orient Green Power may be sending very bearish signals at the moment with a price-to-earnings (or "P/E") ratio of 50.7x, since almost half of all companies in India have P/E ratios under 29x and even P/E's lower than 16x are not unusual. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so lofty.

For instance, Orient Green Power's receding earnings in recent times would have to be some food for thought. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is Orient Green Power's Growth Trending?

There's an inherent assumption that a company should far outperform the market for P/E ratios like Orient Green Power's to be considered reasonable.

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 26%. This means it has also seen a slide in earnings over the longer-term as EPS is down 50% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 23% shows it's an unpleasant look.

In light of this, it's alarming that Orient Green Power's P/E sits above the majority of other companies. 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. There's a very good chance existing shareholders are setting themselves up for future disappointment if the P/E falls to levels more in line with the recent negative growth rates.

The Bottom Line On Orient Green Power's P/E

Shares in Orient Green Power have built up some good momentum lately, which has really inflated its P/E. 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 Orient Green Power revealed its shrinking earnings over the medium-term aren't impacting its high P/E anywhere near as much as we would have predicted, given the market is set to grow. Right now we are increasingly uncomfortable with the high P/E as this earnings performance is highly unlikely to support such positive sentiment for long. If recent medium-term earnings trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
