Masayuki Kichikawa, chief macro strategist at Sumitomo Mitsui DS Asset Management, said the environment is supportive for the Nikkei to rally to 40,500 by end-March, and finish 2025 at 45,400.
“We assume a relatively market-friendly Trump administration”, Kichikawa said.
“The Japanese economy is in a medium-term recovery phase,” he said. “The backdrop is relatively constructive for Japanese equities for next year.”
