Mr. Spero oversaw all facets of the business build out including setting up, growing and developing the business into a top 10 fixed income platform in the market sectors in which the firm competed. Under Mr. Spero’s leadership as head of Fixed Income (and later Head of Global Markets Americas), Nomura’s U.S. Securitized Products Business, which had not existed at the firm prior to Mr. Spero’s arrival, produced strong returns for the firm over a 5 year period.

Mr. Spero recognized the excesses in the subprime market and focused his group on strategies designed to find asymmetrical risk reward opportunities in the sector. Trades implemented by Mr. Spero and his team earned significant profits. A significant portion of these gains were achieved in the derivatives markets and consumed little investment capital.
