Ritamix Global Limited (HKG:1936) shares have had a really impressive month, gaining 28% after a shaky period beforehand. Still, the 30-day jump doesn't change the fact that longer term shareholders have seen their stock decimated by the 65% share price drop in the last twelve months.

Since its price has surged higher, given close to half the companies in Hong Kong have price-to-earnings ratios (or "P/E's") below 9x, you may consider Ritamix Global as a stock to avoid entirely with its 16x P/E ratio. 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 example, consider that Ritamix Global's financial performance has been pretty ordinary lately as earnings growth is non-existent. One possibility is that the P/E is high because investors think the benign earnings growth will improve to outperform the broader market in the near future. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

What Are Growth Metrics Telling Us About The High P/E?

The only time you'd be truly comfortable seeing a P/E as steep as Ritamix Global's is when the company's growth is on track to outshine the market decidedly.

If we review the last year of earnings, the company posted a result that saw barely any deviation from a year ago. Whilst it's an improvement, it wasn't enough to get the company out of the hole it was in, with earnings down 3.3% overall from three years ago. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 22% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

In light of this, it's alarming that Ritamix Global'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 Key Takeaway

Shares in Ritamix Global have built up some good momentum lately, which has really inflated its P/E. Generally, our preference is to limit the use of the price-to-earnings ratio to establishing what the market thinks about the overall health of a company.

We've established that Ritamix Global currently trades on a much higher than expected P/E since its recent earnings have been in decline over the medium-term. When we see earnings heading backwards and underperforming the market forecasts, we suspect the share price is at risk of declining, sending the high P/E lower. Unless the recent medium-term conditions improve markedly, it's very challenging to accept these prices as being reasonable.
