"Unless VOD can secure an increased US dividend, we expect investors to focus on consolidated operations in the near term, and we support a tighter valuation discount for BT."Investec has trimmed its target price for engineering group GKN after its Driveline division suffered from a worse-than-expected weakening in automotive demand and associated operational issues.Investec has maintained its 'hold' rating for GKN and reduced its target price from 240p to 224p.BC
