BSE has reported a remarkable surge in Sensex open interest following a strategic reshuffle in its trading schedule. The exchange witnessed Sensex contracts increase almost four times, demonstrating significant growth in market participation and trading activity.

Dramatic Increase in Open Interest

The most notable development has been the substantial rise in Sensex open interest figures. The data shows a remarkable transformation in trading volumes following the implementation of schedule changes.

Impact of Expiry Day Shift

The surge in open interest has been directly attributed to the strategic decision to move the expiry day from Tuesday to Thursday. This change appears to have created more favorable trading conditions, encouraging increased participation from market participants. Weekly options have emerged as the leading contributor to the enhanced trading volumes, indicating strong investor interest in short-term derivative instruments.

Market Response and Trading Activity

The reshuffle has generated a positive response from the trading community, with weekly options leading the charge in driving overall trading volumes. The shift in expiry timing has provided traders with better alignment to market dynamics and trading preferences, resulting in the substantial increase in contract volumes. This development reflects the exchange's ability to adapt its operations to meet evolving market needs and enhance liquidity in Sensex derivatives.

Indian equity markets staged a recovery on Thursday, with benchmark indices snapping their two-day losing streak as technology stocks led the rally following Infosys' better-than-expected third-quarter results and upgraded revenue growth outlook, injecting fresh optimism into a range-bound market.

Market Performance Overview

The key market indices showed positive momentum, though they settled off their daily highs due to profit-booking at higher levels:

Both indices gave up significant intraday gains in the latter half of the session as investors adopted a cautious stance ahead of key earnings announcements from HDFC Bank and ICICI Bank scheduled for January 17.

Technology Sector Leads Rally

The Nifty IT index emerged as the top sectoral performer, surging 3.34% after Infosys reported better-than-expected results and upgraded its revenue growth outlook. The sector's outperformance reflected investor confidence in sustained demand for technology services.

"Indian equity markets ended marginally higher, supported by positive sentiment in IT & banking," said Siddhartha Khemka, Head of Research, Wealth Management at Motilal Oswal Financial Services.

Banking Sector Momentum Continues

Banking stocks provided additional support, with the Nifty Bank index extending its rally for the fifth consecutive session. The Nifty PSU Bank index gained 1.20%, while heavyweight private sector banks witnessed strong accumulation ahead of their quarterly results.

"Bank Nifty outperformed the broader market, led by strong gains in PSU banks," noted analysts at Bajaj Broking. The banking sector's sustained momentum ahead of major earnings announcements indicates investor optimism about quarterly performance.

Market Breadth and Individual Movers

Market breadth remained mixed, with 1,849 stocks advancing against 2,395 declining on the BSE, while 150 remained unchanged. Notably, 260 stocks hit 52-week lows compared to just 84 touching 52-week highs, indicating continued pressure in the broader market.

Major Decliners:

The Nifty Pharma index declined 1.30%, while the Nifty Metal index slipped 0.50% due to profit-booking after recent gains. The Nifty Smallcap 100 index underperformed, declining 0.28% to 17,362.30.

Technical Outlook and Currency Concerns

"Going ahead, for Nifty, the 100-day EMA zone of 25,600-25,550 will act as immediate support," said Sudeep Shah, Head - Technical and Derivatives Research at SBI Securities. "On the upside, the 50-day EMA zone of 25,850-25,900, which also coincides with the rising trendline zone, will act as immediate resistance."

The Indian rupee remained under pressure, with analysts noting its underperformance relative to Asian peers stems from high dollar demand and retreating foreign capital. Markets are expected to remain volatile in the near term, with earnings from major banking heavyweights and global developments likely to influence sentiment in coming sessions.
