The subdued market reaction suggests that CASTECH Inc.'s (SZSE:002222) recent earnings didn't contain any surprises. However, we believe that investors should be aware of some underlying factors which may be of concern.

The Impact Of Unusual Items On Profit

For anyone who wants to understand CASTECH's profit beyond the statutory numbers, it's important to note that during the last twelve months statutory profit gained from CN¥18m worth of unusual items. We can't deny that higher profits generally leave us optimistic, but we'd prefer it if the profit were to be sustainable. When we crunched the numbers on thousands of publicly listed companies, we found that a boost from unusual items in a given year is often not repeated the next year. And that's as you'd expect, given these boosts are described as 'unusual'. If CASTECH doesn't see that contribution repeat, then all else being equal we'd expect its profit to drop over the current year.
