Citigroup downgraded London's National Grid PLC (NGG, NG.LN) to hold from buy saying now the dust has settled on the surprise rights issue, three issues will determine the company's future: "the UK capex surge, how the capex/dividend is funded, and the likely strategic review of National Grid's US operations." The firm said the new UK government seems committed to the environmental targets it inherited and in response, National Grid has upped its capex. And unless the government policy changes, the capex is only likely to rise further, Citi added. The ADRs slid 3.2% to $37.36 in premarket trading. ScanSource Inc.
