What happened

Shares of semiconductor company Camtek Ltd. (CAMT 1.81%) fell as much as 17.9% on Tuesday, but ended the trading day down 16.1%. The stock's sell-off came after an analyst downgraded Camtek stock's rating. 

So what

Needham & Company changed its rating for the stock from buy to hold this week, according to StreetInsider.com. The downgrade reflects the stock's 29% appreciation in the past three months, as well as Needham & Company's expectations for Camtek to see a deceleration in some of its large orders, as well see the normalization of its PCB (Printed Circuit Board) business.
