BUZZ-Admiral: low quality beat - Bernstein
** British motor and home insurer Admiral down 6.5 pct, bottom of STOXX 600
** H1 profit up 1 pct, dragged down by injury claims costs
** Bernstein says H1 results are a beat for the broker but a low quality one, as higher than expected reserve releases more than offset a weaker underlying loss rate
** "We expect the stock to give back some of its strong YTD performance due to weaker underlying performance" adds Bernstein
