ARM Holdings is giving the technology hardware and equipment sector a lift Monday afternoon. The sector has seen a 15% rise in the last week since the chip giant released its fourth quarter results.

Booming demand for mobile phones, tablet computers and other low-powered devices meant 2010 saw the highest ever annual revenues, profits and cash generation for the group.

Also higher is sector peer Amino Technologies after it slashed full-year losses, as expected, after returning to profitability in the second half. The Cambridge-based online video services provider lost £0.88m in the year ended 30 November compared with an £8.7m deficit the year before.

BT is providing a drag on the FTSE 100 and the fixed line telecommunications sector following the release of its strong third-quarter results on Thursday. Strong growth in broadband subscribers and a pick-up by its global services operation helped the telecoms titan lift profits by almost a third over the past three months.
