U2Bio Co., Ltd. (KOSDAQ:221800) Stock Rockets 64% As Investors Are Less Pessimistic Than Expected

Simply Wall St

U2Bio Co., Ltd. (KOSDAQ:221800) shares have continued their recent momentum with a 64% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 97%.

After such a large jump in price, when almost half of the companies in Korea's Healthcare industry have price-to-sales ratios (or "P/S") below 1.9x, you may consider U2Bio as a stock probably not worth researching with its 3x P/S ratio. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's as high as it is.

What Does U2Bio's P/S Mean For Shareholders?

For example, consider that U2Bio's financial performance has been poor lately as its revenue has been in decline. Perhaps the market believes the company can do enough to outperform the rest of the industry in the near future, which is keeping the P/S ratio high. However, if this isn't the case, investors might get caught out paying too much for the stock.

Although there are no analyst estimates available for U2Bio, take a look at this free data-rich visualisation to see how the company stacks up on earnings, revenue and cash flow.

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

There's an inherent assumption that a company should outperform the industry for P/S ratios like U2Bio's to be considered reasonable.

Retrospectively, the last year delivered a frustrating 2.6% decrease to the company's top line. As a result, revenue from three years ago have also fallen 63% overall. Therefore, it's fair to say the revenue growth recently has been undesirable for the company.

Weighing that medium-term revenue trajectory against the broader industry's one-year forecast for expansion of 17% shows it's an unpleasant look.

With this information, we find it concerning that U2Bio is trading at a P/S higher than 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 heavily on the share price eventually.

The Key Takeaway

U2Bio shares have taken a big step in a northerly direction, but its P/S is elevated as a result. While the price-to-sales ratio shouldn't be the defining factor in whether you buy a stock or not, it's quite a capable barometer of revenue expectations.

We've established that U2Bio currently trades on a much higher than expected P/S since its recent revenues have been in decline over the medium-term. Right now we aren't comfortable with the high P/S as this revenue performance is highly unlikely to support such positive sentiment for long. Should recent medium-term revenue trends persist, it would pose a significant risk to existing shareholders' investments and prospective investors will have a hard time accepting the current value of the stock.

Plus, you should also learn about these 4 warning signs we've spotted with U2Bio (including 2 which are concerning).

Of course, profitable companies with a history of great earnings growth are generally safer bets. So you may wish to see this free collection of other companies that have reasonable P/E ratios and have grown earnings strongly.
