when imos founder and ceo, Hu, was put into jail many years ago, he didn't have enough time to select a good successor. The current CEO is simply not that kind of material (CFO, too).

In this OSAT space, SPIL and ASX are run by very sharp management. AMKR is also a very good company.

Once you have selected good companies, you don't need to worry much since management will take good care of you.
