An uncertain and unpredictable macro-economic environment, with unprecedentedly low interest rates, will continue to create challenges for investors, according to Australian Unity Investments’ joint venture asset managers. Overall, the asset managers agreed that investors need to lower their expectations of returns for the foreseeable future. Prasad Patkar, head of qualitative investment at Platypus Asset Management, said the low growth environment is set to persist for some time and investors should be prepared for low interest rates and limited earnings growth for the medium term. "We believe that further reform and fiscal support from governments is unlikely, and there will be greater reliance on central banks to sustain economies.  The only exception here is possibly Japan. "While the US remains relatively resilient, we would continue to avoid UK and European exposure, and we also believe that Chinese growth momentum has peaked post stimulus."
