With a price-to-earnings (or "P/E") ratio of 11.2x Petronet LNG Limited (NSE:PETRONET) may be sending very bullish signals at the moment, given that almost half of all companies in India have P/E ratios greater than 26x and even P/E's higher than 49x are not unusual. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.
Petronet LNG hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It seems that many are expecting the dour earnings performance to persist, which has repressed the P/E. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

The only time you'd be truly comfortable seeing a P/E as depressed as Petronet LNG's is when the company's growth is on track to lag the market decidedly.
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 7.2%. Regardless, EPS has managed to lift by a handy 6.0% in aggregate from three years ago, thanks to the earlier period of growth. Although it's been a bumpy ride, it's still fair to say the earnings growth recently has been mostly respectable for the company.
Turning to the outlook, the next three years should generate growth of 6.6% per year as estimated by the analysts watching the company. Meanwhile, the rest of the market is forecast to expand by 20% per annum, which is noticeably more attractive.
In light of this, it's understandable that Petronet LNG's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.
Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.
We've established that Petronet LNG maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. It's hard to see the share price rising strongly in the near future under these circumstances.
