Aston Martin Lagonda (LSE:AML) stock sticks out like a sore thumb in the FTSE 250. In this respect, Aston Martin has been remarkably consistent. Aston Martin has suffered from persistent operational losses, production delays, profit warnings, and heavy dilution from multiple emergency capital raises. Gross profit jumped 68% to £213m, pushing the gross margin to 33.8% (from 27.9%). The irony is that the Aston Martin brand hasn't taken as big a hit as some other struggling FTSE 250 names like Dr Martens.
