CoAsia Corporation's (KOSDAQ:045970) 36% Share Price Surge Not Quite Adding Up

CoAsia Corporation (KOSDAQ:045970) shares have continued their recent momentum with a 36% gain in the last month alone. Taking a wider view, although not as strong as the last month, the full year gain of 14% is also fairly reasonable.

Although its price has surged higher, you could still be forgiven for feeling indifferent about CoAsia's P/S ratio of 0.4x, since the median price-to-sales (or "P/S") ratio for the Electronic industry in Korea is also close to 0.8x. However, investors might be overlooking a clear opportunity or potential setback if there is no rational basis for the P/S.

What Does CoAsia's Recent Performance Look Like?

It looks like revenue growth has deserted CoAsia recently, which is not something to boast about. Perhaps the market believes the recent run-of-the-mill revenue performance isn't enough to outperform the industry, which has kept the P/S muted. 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.

How Is CoAsia's Revenue Growth Trending?

There's an inherent assumption that a company should be matching the industry for P/S ratios like CoAsia's to be considered reasonable.

Retrospectively, the last year delivered virtually the same number to the company's top line as the year before. This isn't what shareholders were looking for as it means they've been left with a 17% decline in revenue over the last three years in total. Accordingly, shareholders would have felt downbeat about the medium-term rates of revenue growth.

In contrast to the company, the rest of the industry is expected to grow by 15% over the next year, which really puts the company's recent medium-term revenue decline into perspective.

With this information, we find it concerning that CoAsia is trading at a fairly similar P/S compared to the industry. It seems most investors are ignoring the recent poor growth rate 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 revenue trends is likely to weigh on the share price eventually.

What We Can Learn From CoAsia's P/S?

CoAsia appears to be back in favour with a solid price jump bringing its P/S back in line with other companies in the industry Typically, we'd caution against reading too much into price-to-sales ratios when settling on investment decisions, though it can reveal plenty about what other market participants think about the company.

We find it unexpected that CoAsia trades at a P/S ratio that is comparable to the rest of the industry, despite experiencing declining revenues during the medium-term, while the industry as a whole is expected to grow. Even though it matches the industry, we're uncomfortable with the current P/S ratio, as this dismal revenue performance is unlikely to support a more positive sentiment for long. If recent medium-term revenue trends continue, it will place shareholders' investments at risk and potential investors in danger of paying an unnecessary premium.

It's always necessary to consider the ever-present spectre of investment risk. We've identified 2 warning signs with CoAsia, and understanding them should be part of your investment process.
