Sector movers: Tech sector dragged lower by ARM

The technology hardware and equipment sector was among the worst performing sectors, dragged lower by chip designer ARM Holdings.Shares of ARM fell lower despite its second quarter earnings per share (EPS) coming in well ahead of expectations, as demand for the company's technology continues to grow."Profits for Q2 beat consensus by almost 20%, but an expected weakening in royalties in H2 is likely to limit full-year upgrades to around 5%," noted Peel Hunt's analyst Paul Morland. Rising higher, however, were electronic and electrical equipment stocks, with small caps Dialight and Volex providing a boost.LED lighting developer Dialight reported a half year underlying profit growth of 17%, increased its dividend and said it is increasingly confident of exceeding full year forecasts. Meanwhile, electrical, digital and optical connections provider Volex said trading in the first quarter of its financial year ending 2012 continued to be buoyant with revenue well ahead of the same period last year.
