Shanghai International Airport Co., Ltd.'s (SHSE:600009) robust earnings report didn't manage to move the market for its stock. Our analysis suggests that shareholders have noticed something concerning in the numbers.

The Impact Of Unusual Items On Profit

Importantly, our data indicates that Shanghai International Airport's profit received a boost of CN¥78m in unusual items, over the last year. While it's always nice to have higher profit, a large contribution from unusual items sometimes dampens our enthusiasm. We ran the numbers on most publicly listed companies worldwide, and it's very common for unusual items to be once-off in nature. And that's as you'd expect, given these boosts are described as 'unusual'. Assuming those unusual items don't show up again in the current year, we'd thus expect profit to be weaker next year (in the absence of business growth, that is).
