HG Semiconductor Limited (HKG:6908) shareholders are no doubt pleased to see that the share price has bounced 25% in the last month, although it is still struggling to make up recently lost ground. Still, the 30-day jump doesn't change the fact that longer term shareholders have seen their stock decimated by the 79% share price drop in the last twelve months.

Following the firm bounce in price, given around half the companies in Hong Kong's Semiconductor industry have price-to-sales ratios (or "P/S") below 1.3x, you may consider HG Semiconductor as a stock to avoid entirely with its 4.9x P/S ratio. However, the P/S might be quite high for a reason and it requires further investigation to determine if it's justified.

What Does HG Semiconductor's Recent Performance Look Like?

For instance, HG Semiconductor's receding revenue in recent times would have to be some food for thought. It might be that many expect the company to still outplay most other companies over the coming period, which has kept the P/S from collapsing. However, if this isn't the case, investors might get caught out paying too much for the stock.

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

HG Semiconductor's P/S ratio would be typical for a company that's expected to deliver very strong growth, and importantly, perform much better than the industry.

In reviewing the last year of financials, we were disheartened to see the company's revenues fell to the tune of 4.5%. As a result, revenue from three years ago have also fallen 54% overall. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 8.4% shows it's an unpleasant look.

In light of this, it's alarming that HG Semiconductor's P/S sits above the majority of other companies. 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/S falls to levels more in line with the recent negative growth rates.

What We Can Learn From HG Semiconductor's P/S?

Shares in HG Semiconductor have seen a strong upwards swing lately, which has really helped boost its P/S figure. Using the price-to-sales 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 HG Semiconductor currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. With a revenue decline on investors' minds, the likelihood of a souring sentiment is quite high which could send the P/S back in line with what we'd expect. Unless the recent medium-term conditions improve markedly, investors will have a hard time accepting the share price as fair value.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 5 warning signs with HG Semiconductor (at least 2 which make us uncomfortable), and understanding these should be part of your investment process.
