[Goldman Sachs trader Joaquin de Soto moves to Castle Investment] according to people familiar with the matter, Joaquin de Soto, Goldman's chief inflation trader in London, moved to hedge fund Castle Investment (Citadel LLC). Soto's job-hopping is just one of several recent job-hopping cases as Wall Street financial firms compete to profit from rapidly rising consumer prices and the Fed's efforts to rein in prices. Trading in inflation-linked government bonds and derivatives has traditionally been considered a niche market, but wide swings in the consumer price index have made it a big business.
