Despite the positive momentum, foreign institutional investors (FIIs) continued to pare holdings. As per NSDL data, FIIs sold equities worth Rs 11,169 crore in September up to the 12th. This took total FII outflows in 2025 to a substantial Rs 1,82,109 crore.
Rally validates time-based observation
In the previous outlook, September 10 was identified as a potential high-momentum date. The market validated this projection with a strong gap-up opening on September 10, which triggered a non-stop rally in the Nifty that carried forward through the week.
“This reinforces the significance of time-based observation in identifying market momentum,” said Harshubh Mahesh Shah, Director at Wealthview Analytics.
