Following this estrangement he went into business for himself with the support of Lubbocks and Forster, an eminent banking house. He made the bulk of his fortune by profitably financing Government borrowing. There is a story that he made his fortune as a result of speculation on the outcome of the Battle of Waterloo: "The Sunday Times" reported in Ricardo's obituary, published on 14 September 1823, that during the battle Ricardo "netted upwards of a million sterling", a huge sum at the time, and this was later popularised by the economist Paul Samuelson; in reality Ricardo was already very rich and in June 1815 sold his latest government stock before the result of the battle was known in London, so missing half of the rise.
