HEXUS.sharewatch: AMD, ARM and NVIDIA jump on Oracle rumours

AMD investors had at least two extra factors to take into account last Friday. First the chip-maker lowered its guidance for Q3 revenues before the start of play.

This would usually cause a negative share-price move but, given that Intel had already made such an announcement itself, the news was probably already priced into AMD's shares and was presumably better than hoped.

Then it was reported that the Oracle boss - Larry Ellison - said his company is looking to acquire chip-makers. Cue a frenzy of speculation about who Oracle might buy with AMD near the top of the list due to its enterprise credentials.

The other major chip companies were also caught up on the speculation, with NVIDIA building on a raft of positive analyst reports and the afterglow of the GPU Technology conference. One of the biggest reasons for the positive vibes directed at NVIDIA is a feeling that Tegra 2 may finally be set to deliver on its promise.

Oracle investors, however, seem less excited about a possible chip acquisition. In another positive week for tech stocks Oracle joined only Microsoft in negative territory.
