JCY Q2 may highly still perform well, but Q3, Q4 onwards, still a bit unknown.
As we see recent few week, HDD price out there is start going down already, quite a lot lately in recent week.

You need to compare the Q2 result with Q1.

As HDD price should have passed its peak level, and should normalised as time goes, which may affect the future earning result and sustainability of Q1 and Q2 result.
