> KOSPI is crashing because the memory manufacturers are priced for continued bubble orders books. Those orders cannot be sustained

Could you explain what that means? Are they overbooking and will not be able to meet those particular projections? Would a single segment of one industry cause a reverberation throughout?

It means that there will not be this level of memory demand for much longer. I tend to agree. Right now there is far more demand than supply, so they are cashing in while they can. It will be resolved one way or another eventually, current margins are not sustainable for the long term and will be resolved either via demand destruction or an increase of supply. Likely a combination of both.
