Open Interest and Volume Dynamics
On 27 January 2026, CDSL's open interest rose sharply from 36,017 contracts to 39,711, an absolute increase of 3,694 contracts. This 10.26% jump in OI is accompanied by a futures volume of 17,496 contracts, indicating robust trading activity in the derivatives market. The futures value stood at approximately ₹20,108.99 lakhs, while the options segment exhibited an extraordinarily high notional value of ₹9,660.37 crores, underscoring significant speculative interest.
The total traded value across futures and options was ₹23,060.13 lakhs, reflecting strong liquidity and active participation. The underlying stock price closed at ₹1,349, outperforming its sector by 0.31% and the Sensex by 1.73% on the day, with a one-day return of 2.11% compared to the sector's 1.96% and Sensex's 0.38% gains.
Market Positioning and Moving Averages
Despite the positive price movement, CDSL is trading below all key moving averages — 5-day, 20-day, 50-day, 100-day, and 200-day — signalling a prevailing downtrend in the medium to long term. This divergence between short-term price gains and longer-term technical indicators suggests that while traders are actively positioning in the derivatives market, broader investor confidence remains cautious.
Investor participation, as measured by delivery volumes, has declined by 8.13% against the five-day average, with delivery volumes falling to 5.5 lakh shares on 27 January. This drop in delivery volume indicates reduced conviction among long-term holders, potentially signalling profit-booking or a wait-and-watch stance amid uncertain market conditions.

Implications of the Open Interest Surge
The 10.26% increase in open interest is a significant development, often interpreted as a sign of fresh capital entering the market or existing traders increasing their positions. In CDSL's case, the rise in OI alongside a moderate price gain suggests that market participants may be building directional bets, possibly anticipating a rebound or volatility in the near term.
However, the fact that the stock remains below all major moving averages tempers bullish enthusiasm. It implies that while short-term traders are active, the broader trend remains bearish or neutral. This scenario often leads to increased volatility as market participants reassess their positions based on upcoming corporate developments or macroeconomic cues.
Mojo Score and Analyst Ratings
CDSL currently holds a Mojo Score of 37.0, categorised as a 'Sell' rating, downgraded from a previous 'Hold' on 12 January 2026. This downgrade reflects deteriorating fundamentals or technical outlooks as assessed by MarketsMOJO's proprietary analytics. The market capitalisation grade stands at 3, indicating a small-cap status with moderate liquidity and market presence.
Given the mixed signals from derivatives activity and technical indicators, investors should exercise caution. The stock's liquidity is sufficient for sizeable trades, with a 2% threshold of the five-day average traded value allowing for trade sizes up to ₹5.65 crores without significant market impact.
Sector and Market Context
Operating within the capital markets sector, CDSL's performance is closely tied to broader market sentiment and regulatory developments affecting depository services. The sector's one-day return of 1.96% on 27 January 2026, slightly lagging CDSL's 2.11%, indicates that the company is marginally outperforming peers despite its technical challenges.
Investors should monitor upcoming earnings announcements, policy changes, and macroeconomic indicators that could influence capital market activity and, by extension, CDSL's stock and derivatives performance.

Investor Takeaways and Outlook
The surge in open interest in CDSL's derivatives market signals increased speculative interest and potential directional bets. However, the stock's position below all major moving averages and declining delivery volumes suggest that the broader investor base remains cautious or bearish.
For traders, the heightened OI and volume may present short-term trading opportunities, especially if volatility increases. Long-term investors should weigh the recent downgrade to a 'Sell' rating and monitor fundamental developments closely before increasing exposure.
Given the stock's small-cap status and moderate liquidity, investors should also consider market impact and execution risks when planning sizeable trades.
Conclusion
Central Depository Services (India) Ltd's recent open interest surge reflects a dynamic derivatives market with active positioning, yet the underlying technical and fundamental indicators counsel prudence. The stock's mixed signals underscore the importance of a balanced approach, combining technical analysis with fundamental insights to navigate the evolving capital markets landscape effectively.
