Weibo Corporation's (NASDAQ:WB) price-to-earnings (or "P/E") ratio of 7x might make it look like a strong buy right now compared to the market in the United States, where around half of the companies have P/E ratios above 19x and even P/E's above 34x are quite common. Although, it's not wise to just take the P/E at face value as there may be an explanation why it's so limited.

We've found 21 US stocks that are forecast to pay a dividend yield of over 6% next year. See the full list for free.

Recent times have been advantageous for Weibo as its earnings have been rising faster than most other companies. It might be that many expect the strong earnings performance to degrade substantially, which has repressed the P/E. 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 out of favour.

What Are Growth Metrics Telling Us About The Low P/E?

In order to justify its P/E ratio, Weibo would need to produce anemic growth that's substantially trailing the market.

Taking a look back first, we see that the company grew earnings per share by an impressive 22% last year. The latest three year period has also seen a 8.6% overall rise in EPS, aided extensively by its short-term performance. So we can start by confirming that the company has actually done a good job of growing earnings over that time.

Shifting to the future, estimates from the analysts covering the company suggest earnings should grow by 3.7% each year over the next three years. That's shaping up to be materially lower than the 11% each year growth forecast for the broader market.

In light of this, it's understandable that Weibo's P/E sits below the majority of other companies. It seems most investors are expecting to see limited future growth and are only willing to pay a reduced amount for the stock.

What We Can Learn From Weibo's P/E?

It's argued the price-to-earnings ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

We've established that Weibo maintains its low P/E on the weakness of its forecast growth being lower than the wider market, as expected. At this stage investors feel the potential for an improvement in earnings isn't great enough to justify a higher P/E ratio. It's hard to see the share price rising strongly in the near future under these circumstances.
