Immuno-Biological Laboratories Co., Ltd. (TSE:4570) Shares May Have Slumped 47% But Getting In Cheap Is Still Unlikely

Listen to the news

Immuno-Biological Laboratories Co., Ltd. (TSE:4570) shares have retraced a considerable 47% in the last month, reversing a fair amount of their solid recent performance. Of course, over the longer-term many would still wish they owned shares as the stock's price has soared 255% in the last twelve months.

In spite of the heavy fall in price, Immuno-Biological Laboratories' price-to-earnings (or "P/E") ratio of 48x might still make it look like a strong sell right now compared to the market in Japan, where around half of the companies have P/E ratios below 14x and even P/E's below 10x are quite common. Nonetheless, we'd need to dig a little deeper to determine if there is a rational basis for the highly elevated P/E.

Immuno-Biological Laboratories certainly has been doing a great job lately as it's been growing earnings at a really rapid pace. The P/E is probably high because investors think this strong earnings growth will be enough to outperform the broader market in the near future. If not, then existing shareholders might be a little nervous about the viability of the share price.

Is There Enough Growth For Immuno-Biological Laboratories?

In order to justify its P/E ratio, Immuno-Biological Laboratories would need to produce outstanding growth well in excess of the market.

Retrospectively, the last year delivered an exceptional 38% gain to the company's bottom line. However, the latest three year period hasn't been as great in aggregate as it didn't manage to provide any growth at all. Accordingly, shareholders probably wouldn't have been overly satisfied with the unstable medium-term growth rates.

Weighing that recent medium-term earnings trajectory against the broader market's one-year forecast for expansion of 8.9% shows it's noticeably less attractive on an annualised basis.

In light of this, it's alarming that Immuno-Biological Laboratories' P/E sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates and are hoping for a turnaround in the company's business prospects. Only the boldest would assume these prices are sustainable as a continuation of recent earnings trends is likely to weigh heavily on the share price eventually.

What We Can Learn From Immuno-Biological Laboratories' P/E?

Even after such a strong price drop, Immuno-Biological Laboratories' P/E still exceeds the rest of the market significantly. 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.

Our examination of Immuno-Biological Laboratories revealed its three-year earnings trends aren't impacting its high P/E anywhere near as much as we would have predicted, given they look worse than current market expectations. When we see weak earnings with slower than market growth, 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.
