Investors were disappointed by Lanzhou LS Heavy Equipment Co., Ltd's (SHSE:603169 ) latest earnings release. We did some analysis, and found that there are some reasons to be cautious about the headline numbers.

The Impact Of Unusual Items On Profit

Importantly, our data indicates that Lanzhou LS Heavy Equipment's profit received a boost of CN¥37m in unusual items, over the last year. While we like to see profit increases, we tend to be a little more cautious when unusual items have made a big contribution. When we analysed the vast majority of listed companies worldwide, we found that significant unusual items are often not repeated. 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).
