IGG Inc (HKG:799) shares have continued their recent momentum with a 31% gain in the last month alone. The last 30 days bring the annual gain to a very sharp 31%.

Although its price has surged higher, IGG may still be sending buy signals at present with its price-to-sales (or "P/S") ratio of 0.9x, considering almost half of all companies in the Entertainment industry in Hong Kong have P/S ratios greater than 1.6x and even P/S higher than 4x aren't out of the ordinary. Although, it's not wise to just take the P/S at face value as there may be an explanation why it's limited.

What Does IGG's Recent Performance Look Like?

With revenue growth that's inferior to most other companies of late, IGG has been relatively sluggish. It seems that many are expecting the uninspiring revenue performance to persist, which has repressed the growth of the P/S ratio. If this is the case, then existing shareholders will probably struggle to get excited about the future direction of the share price.

How Is IGG's Revenue Growth Trending?

In order to justify its P/S ratio, IGG would need to produce sluggish growth that's trailing the industry.

Retrospectively, the last year delivered an exceptional 19% gain to the company's top line. Still, revenue has fallen 12% in total from three years ago, which is quite disappointing. So unfortunately, we have to acknowledge that the company has not done a great job of growing revenues over that time.

Looking ahead now, revenue is anticipated to climb by 7.1% during the coming year according to the six analysts following the company. That's shaping up to be materially lower than the 36% growth forecast for the broader industry.

In light of this, it's understandable that IGG's P/S 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 IGG's P/S?

Despite IGG's share price climbing recently, its P/S still lags most other companies. It's argued the price-to-sales ratio is an inferior measure of value within certain industries, but it can be a powerful business sentiment indicator.

As expected, our analysis of IGG's analyst forecasts confirms that the company's underwhelming revenue outlook is a major contributor to its low P/S. Shareholders' pessimism on the revenue prospects for the company seems to be the main contributor to the depressed P/S. The company will need a change of fortune to justify the P/S rising higher in the future.
