Amtech downgraded GOOG to Hold from Buy due to the following: 1) they are more cautious on expenses in the near-term, 2) cap-ex outlook is uncertain -- will likely be much greater than most expect and 3) they see risk to Internet business models on regulatory uncertainty regarding net neutrality vs. tiered broadband services. They say they cannot predict the outcome on net neutrality and do not see resolution within the next 12-months. Firm notes that they are equally concerned with regulatory uncertainty for YHOO and reiterate their Hold rating.
