0943 GMT [Dow Jones] Altium Securities downgrades SDL (SDL.LN) to hold from buy following the stock's 24% outperformance over the last three months. Remains convinced of the medium-term attractions of the market, but in the absence of further upgrades believes the stock is fairly valued. "One note of caution is with regard to the recent strengthening of the pound against the dollar and euro, which if it continues will provide a headwind to both revenues and profits." Has 525p price target on the stock. Shares +1.3% at 552p. ([email protected]) Contact us in London. +44-20-7842-9464 [email protected] (END) Dow Jones Newswires July 26, 2010 05:43 ET (09:43 GMT)
