researcher, I agree with you about THK and have added some shares on this huge volume sell-off also. Risk/reward is more compelling now than it has been in a long time, IMHO.
Not without warts, as you mention. Consistent Form 144 selling, acquisition headaches, potential for lowered guidance if they miss again for Q2.....but its been beaten down so much, perhaps discounting these concerns?.
Just wish I knew the source of the selling.
