Shouldn't conclude this. The present move up is based on their recent business announcement, plus the 5% stake that a major hedge fund announced a few days ago. There's no pending buyout, sorry to say.
VECO is a secular growth story, not cyclical. There is a big difference between the two. Traditional semi-equipment providers are cyclical, VECO is secular. Therefore it is a buy out candidate although when and if is obviously unknown.
