The Sensex closed 0.7% lower on October 31 following its earlier 13-month high, as profit booking emerged in technology and financial counters while hawkish U.S. Federal Reserve commentary guided sentiment toward caution. Analysts noted no structural trend reversal but short term positioning adjustment ahead of policy clarity windows into November. Global risk appetite wavered as macro tightening scenarios remain unresolved, guiding selective rotation within institutional portfolios. Domestic flows remained supportive, but headline index movement reflected measured supply absorption across high beta pockets and earnings season alignment checks.
