Realtek Semiconductor Corp.'s (TWSE:2379) Popularity With Investors Is Under Threat From Overpricing

It's not a stretch to say that Realtek Semiconductor Corp.'s (TWSE:2379) price-to-earnings (or "P/E") ratio of 20x right now seems quite "middle-of-the-road" compared to the market in Taiwan, where the median P/E ratio is around 21x. Although, it's not wise to simply ignore the P/E without explanation as investors may be disregarding a distinct opportunity or a costly mistake.

Recent times have been advantageous for Realtek Semiconductor as its earnings have been rising faster than most other companies. One possibility is that the P/E is moderate because investors think this strong earnings performance might be about to tail off. If you like the company, you'd be hoping this isn't the case so that you could potentially pick up some stock while it's not quite in favour.

Does Growth Match The P/E?

There's an inherent assumption that a company should be matching the market for P/E ratios like Realtek Semiconductor's to be considered reasonable.

Taking a look back first, we see that the company grew earnings per share by an impressive 55% last year. However, this wasn't enough as the latest three year period has seen a very unpleasant 5.8% drop in EPS in aggregate. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 19% during the coming year according to the analysts following the company. That's shaping up to be materially lower than the 25% growth forecast for the broader market.

With this information, we find it interesting that Realtek Semiconductor is trading at a fairly similar P/E to the market. It seems most investors are ignoring the fairly limited growth expectations and are willing to pay up for exposure to the stock. Maintaining these prices will be difficult to achieve as this level of earnings growth is likely to weigh down the shares eventually.

The Bottom Line On Realtek Semiconductor's P/E

Using the price-to-earnings ratio alone to determine if you should sell your stock isn't sensible, however it can be a practical guide to the company's future prospects.

We've established that Realtek Semiconductor currently trades on a higher than expected P/E since its forecast growth is lower than the wider market. When we see a weak earnings outlook with slower than market growth, we suspect the share price is at risk of declining, sending the moderate P/E lower. Unless these conditions improve, it's challenging to accept these prices as being reasonable.
