There's Reason For Concern Over Walsin Lihwa Corporation's (TWSE:1605) Massive 26% Price Jump

Walsin Lihwa Corporation (TWSE:1605) shares have had a really impressive month, gaining 26% after a shaky period beforehand. Unfortunately, the gains of the last month did little to right the losses of the last year with the stock still down 20% over that time.

Since its price has surged higher, given close to half the companies in Taiwan have price-to-earnings ratios (or "P/E's") below 21x, you may consider Walsin Lihwa as a stock to avoid entirely with its 34.1x 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 Walsin Lihwa's financial performance has been poor lately as its earnings have been in decline. One possibility is that the P/E is high because investors think the company will still do enough to outperform the broader market in the near future. If not, then existing shareholders may be quite nervous about the viability of the share price.

How Is Walsin Lihwa's Growth Trending?

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

If we review the last year of earnings, dishearteningly the company's profits fell to the tune of 44%. As a result, earnings from three years ago have also fallen 76% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Comparing that to the market, which is predicted to deliver 25% growth in the next 12 months, the company's downward momentum based on recent medium-term earnings results is a sobering picture.

With this information, we find it concerning that Walsin Lihwa is trading at a P/E higher than the market. It seems most investors are ignoring the recent poor growth rate and are hoping for a turnaround in the company's business prospects. 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 Walsin Lihwa have built up some good momentum lately, which has really inflated its P/E. 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.

We've established that Walsin Lihwa 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.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 4 warning signs with Walsin Lihwa (at least 2 which are significant), and understanding these should be part of your investment process.
