First Ship Lease Trust (SGX:D8DU) shares have had a horrible month, losing 54% after a relatively good period beforehand. For any long-term shareholders, the last month ends a year to forget by locking in a 62% share price decline.

Although its price has dipped substantially, there still wouldn't be many who think First Ship Lease Trust's price-to-earnings (or "P/E") ratio of 10.9x is worth a mention when the median P/E in Singapore is similar at about 11x. While this might not raise any eyebrows, if the P/E ratio is not justified investors could be missing out on a potential opportunity or ignoring looming disappointment.

As an illustration, earnings have deteriorated at First Ship Lease Trust over the last year, which is not ideal at all. One possibility is that the P/E is moderate because investors think the company might still do enough to be in line with the broader market in the near future. If not, then existing shareholders may be a little nervous about the viability of the share price.

How Is First Ship Lease Trust's Growth Trending?

The only time you'd be comfortable seeing a P/E like First Ship Lease Trust's is when the company's growth is tracking the market closely.

Retrospectively, the last year delivered a frustrating 72% decrease to the company's bottom line. As a result, earnings from three years ago have also fallen 41% overall. So unfortunately, we have to acknowledge that the company has not done a great job of growing earnings over that time.

Weighing that medium-term earnings trajectory against the broader market's one-year forecast for expansion of 11% shows it's an unpleasant look.

With this information, we find it concerning that First Ship Lease Trust is trading at a fairly similar P/E to the market. Apparently many investors in the company are way less bearish than recent times would indicate and aren't willing to let go of their stock right now. There's a 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.

What We Can Learn From First Ship Lease Trust's P/E?

With its share price falling into a hole, the P/E for First Ship Lease Trust looks quite average now. While the price-to-earnings ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of earnings expectations.
