The Weibo Corporation (NASDAQ:WB) share price has done very well over the last month, posting an excellent gain of 35%. Not all shareholders will be feeling jubilant, since the share price is still down a very disappointing 21% in the last twelve months.

Although its price has surged higher, given about half the companies in the United States have price-to-earnings ratios (or "P/E's") above 19x, you may still consider Weibo as a highly attractive investment with its 7.5x P/E ratio. However, the P/E might be quite low for a reason and it requires further investigation to determine if it's justified.

Weibo certainly has been doing a good job lately as its earnings growth has been positive while most other companies have been seeing their earnings go backwards. One possibility is that the P/E is low because investors think the company's earnings are going to fall away like everyone else's soon. 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?

Weibo's P/E ratio would be typical for a company that's expected to deliver very poor growth or even falling earnings, and importantly, perform much worse than the market.

Retrospectively, the last year delivered a decent 4.4% gain to the company's bottom line. This was backed up an excellent period prior to see EPS up by 56% in total over the last three years. Accordingly, shareholders would have probably welcomed those medium-term rates of earnings growth.

Looking ahead now, EPS is anticipated to climb by 3.7% each year during the coming three years according to the analysts following the company. Meanwhile, the rest of the market is forecast to expand by 10% per annum, which is noticeably more attractive.

In light of this, it's understandable that Weibo's P/E sits below the majority of other companies. Apparently many shareholders weren't comfortable holding on while the company is potentially eyeing a less prosperous future.

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

Shares in Weibo are going to need a lot more upward momentum to get the company's P/E out of its slump. 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. Right now shareholders are accepting the low P/E as they concede future earnings probably won't provide any pleasant surprises. Unless these conditions improve, they will continue to form a barrier for the share price around these levels.
