Aston Martin Lagonda downgraded to Neutral from Buy at Goldman Sachs. Goldman Sachs analyst George Galliers downgraded Aston Martin Lagonda to Neutral from Buy with a price target of 520 GBp, down from 620 GBp. The analyst says Goldman's database to track luxury car residual values indicates that prices have softened across brands and regions. This bears risk for prices and volumes in the luxury new car market, and Aston Martin is most at risk, Galliers tells investors in a research note.
