Sundart Holdings Limited (HKG:1568) shareholders that were waiting for something to happen have been dealt a blow with a 32% share price drop in the last month. Instead of being rewarded, shareholders who have already held through the last twelve months are now sitting on a 18% share price drop.

In spite of the heavy fall in price, Sundart Holdings' price-to-earnings (or "P/E") ratio of 2.1x might still make it look like a strong buy right now compared to the market in Hong Kong, where around half of the companies have P/E ratios above 9x and even P/E's above 18x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly reduced P/E.

Sundart Holdings has been doing a good job lately as it's been growing earnings at a solid pace. It might be that many expect the respectable earnings performance to degrade substantially, which has repressed the P/E. If that doesn't eventuate, then existing shareholders have reason to be optimistic about the future direction of the share price.

Does Growth Match The Low P/E?

There's an inherent assumption that a company should far underperform the market for P/E ratios like Sundart Holdings' to be considered reasonable.

If we review the last year of earnings growth, the company posted a worthy increase of 15%. Still, lamentably EPS has fallen 19% in aggregate from three years ago, which is disappointing. 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 21% shows it's an unpleasant look.

In light of this, it's understandable that Sundart Holdings' P/E would sit below the majority of other companies. However, we think shrinking earnings are unlikely to lead to a stable P/E over the longer term, which could set up shareholders for future disappointment. Even just maintaining these prices could be difficult to achieve as recent earnings trends are already weighing down the shares.

The Final Word

Shares in Sundart Holdings have plummeted and its P/E is now low enough to touch the ground. Typically, we'd caution against reading too much into price-to-earnings ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

As we suspected, our examination of Sundart Holdings revealed its shrinking earnings over the medium-term are contributing to its low P/E, given the market is set to grow. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. Unless the recent medium-term conditions improve, they will continue to form a barrier for the share price around these levels.
