It is too early to tell last week's drop constitutes a down trend or just a temp consolidation.
So far, last week's less than 10% drop in SH index against the 200% gain from last year is just a consolidation, not a full crash or even a correction.
A full crash (40% or more) is unlikely to happen in China stocks until after the 08 Olympics around 2009.
But you know my guess is as good as everyone else's.
