Frequently Asked Questions (FAQs)

Q1: Why did the market trend sideways today?

A1: After an initial volatile period driven by a gap-up opening, the major indices (Nifty and Sensex) settled into a narrow trading range. This sideways trend indicates that bulls and bears were in a state of equilibrium, with no clear directional bias. Traders likely waited for a decisive breakout.

Q2: How did Nifty's expiry day affect the market?

A2: Today being Nifty's expiry day, the market was highly volatile in the first hour. Traders and investors were adjusting their positions, which contributed to the initial fluctuations. The subsequent range-bound movement is common on expiry days as option writers defend their positions.

Q3: What was the key takeaway from the FII and DII activity today?

A3: The FII DII data showed a mixed picture. While Domestic Institutional Investors (DIIs) were net buyers with a significant positive value, Foreign Institutional Investors (FIIs) were also net buyers in the overall market (All Exchanges) but were net sellers on the NSE. This suggests a mixed sentiment, with domestic funds providing strong support while foreign funds engaged in tactical profit-booking in some segments.
