Why Investors Shouldn't Be Surprised By Unimicron Technology Corp.'s (TWSE:3037) 28% Share Price Surge

Unimicron Technology Corp. (TWSE:3037) shareholders would be excited to see that the share price has had a great month, posting a 28% gain and recovering from prior weakness. Looking further back, the 14% rise over the last twelve months isn't too bad notwithstanding the strength over the last 30 days.

Following the firm bounce in price, given close to half the companies in Taiwan have price-to-earnings ratios (or "P/E's") below 21x, you may consider Unimicron Technology as a stock to avoid entirely with its 33.8x P/E ratio. However, the P/E might be quite high for a reason and it requires further investigation to determine if it's justified.

Unimicron Technology hasn't been tracking well recently as its declining earnings compare poorly to other companies, which have seen some growth on average. It might be that many expect the dour earnings performance to recover substantially, which has kept the P/E from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Unimicron Technology's Growth Trending?

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

Taking a look back first, the company's earnings per share growth last year wasn't something to get excited about as it posted a disappointing decline of 52%. This means it has also seen a slide in earnings over the longer-term as EPS is down 26% in total over the last three years. Accordingly, shareholders would have felt downbeat about the medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 109% during the coming year according to the analysts following the company. Meanwhile, the rest of the market is forecast to only expand by 24%, which is noticeably less attractive.

In light of this, it's understandable that Unimicron Technology's P/E sits above the majority of other companies. It seems most investors are expecting this strong future growth and are willing to pay more for the stock.

The Bottom Line On Unimicron Technology's P/E
