0225 GMT - The State Street risk appetite index fell in September to its weakest reading since March's outbreak of war in Iran. Equity allocations remain historically high at 56.6%, but fell 0.8 percentage point in September, the data shows. Meanwhile, fixed income allocations recorded their largest monthly increase in just over five years--but holdings remain historically low, it adds. September's surge suggests long-term investors are finally responding to higher sovereign yields despite the difficult macroeconomic outlook, the bank says. State Street derives its findings by monitoring allocation patterns by investors active under its $57.9 trillion in funds under management.
