How Shanghai SK Petroleum & Chemical Equipment Has Been Performing

For example, consider that Shanghai SK Petroleum & Chemical Equipment's financial performance has been pretty ordinary lately as revenue growth is non-existent. It might be that many are expecting an improvement to the uninspiring revenue performance over the coming period, which has kept the P/S from collapsing. You'd really hope so, otherwise you're paying a pretty hefty price for no particular reason.

How Is Shanghai SK Petroleum & Chemical Equipment's Revenue Growth Trending?

In order to justify its P/S ratio, Shanghai SK Petroleum & Chemical Equipment would need to produce impressive growth in excess of the industry.

If we review the last year of revenue, the company posted a result that saw barely any deviation from a year ago. That's essentially a continuation of what we've seen over the last three years, as its revenue growth has been virtually non-existent for that entire period. Accordingly, shareholders probably wouldn't have been satisfied with the complete absence of medium-term growth.

Comparing the recent medium-term revenue trends against the industry's one-year growth forecast of 16% shows it's noticeably less attractive.

In light of this, it's alarming that Shanghai SK Petroleum & Chemical Equipment's P/S sits above the majority of other companies. It seems most investors are ignoring the fairly limited recent growth rates 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.

What We Can Learn From Shanghai SK Petroleum & Chemical Equipment's P/S?

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.

The fact that Shanghai SK Petroleum & Chemical Equipment currently trades on a higher P/S relative to the industry is an oddity, since its recent three-year growth is lower than the wider industry forecast. When we observe slower-than-industry revenue growth alongside a high P/S ratio, we assume there to be a significant risk of the share price decreasing, which would result in a lower P/S ratio. If recent medium-term revenue trends continue, it will place shareholders' investments at significant risk and potential investors in danger of paying an excessive premium.
