HF Sinclair Corporation's (NYSE:DINO) price-to-earnings (or "P/E") ratio of 7.5x might make it look like a strong buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 17x and even P/E's above 32x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

Recent times haven't been advantageous for HF Sinclair as its earnings have been falling quicker than most other companies. The P/E is probably low because investors think this poor earnings performance isn't going to improve at all. If you still like the company, you'd want its earnings trajectory to turn around before making any decisions. Or at the very least, you'd be hoping the earnings slide doesn't get any worse if your plan is to pick up some stock while it's out of favour.

How Is HF Sinclair's Growth Trending?

HF Sinclair's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Retrospectively, the last year delivered a frustrating 42% decrease to the company's bottom line. This has erased any of its gains during the last three years, with practically no change in EPS being achieved in total. So it appears to us that the company has had a mixed result in terms of growing earnings over that time.

Looking ahead now, EPS is anticipated to slump, contracting by 8.7% per year during the coming three years according to the twelve analysts following the company. With the market predicted to deliver 10% growth per year, that's a disappointing outcome.

With this information, we are not surprised that HF Sinclair is trading at a P/E lower than the market. However, shrinking earnings are unlikely to lead to a stable P/E over the longer term. There's potential for the P/E to fall to even lower levels if the company doesn't improve its profitability.

The Bottom Line On HF Sinclair's P/E

We'd say the price-to-earnings ratio's power isn't primarily as a valuation instrument but rather to gauge current investor sentiment and future expectations.

As we suspected, our examination of HF Sinclair's analyst forecasts revealed that its outlook for shrinking earnings is contributing to its low P/E. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
