Indian stock markets are expected to remain cautious in the final trading week of 2025, with Nifty potentially trading in a 25800-26200 range. This cautious outlook is driven by increased bearish bets from proprietary traders and foreign portfolio investors (FPIs) in index derivatives. Trading volumes are anticipated to be thin due to the year-end holidays, with the week also featuring the expiry of Nifty and Bank Nifty derivatives.
