Central Depository Services Sees Sharp Open Interest Surge Amid Mixed Market Signals

Open Interest and Volume Dynamics

On 27 January 2026, CDSL's open interest (OI) in futures and options contracts rose from 36,017 to 40,388 contracts, an absolute increase of 4,371 contracts or 12.14%. This uptick in OI was accompanied by a futures volume of 22,216 contracts, translating to a futures value of approximately ₹24,778 lakhs. The options segment exhibited a significantly higher notional value at ₹12,370.18 crores, underscoring the prominence of options trading in the stock's derivatives market.

The combined derivatives value stood at ₹28,530 lakhs, reflecting robust liquidity and active participation from institutional and retail traders alike. The underlying stock price closed at ₹1,347, with a daily gain of 1.91%, though this was marginally below the sector's 2.26% advance and the Sensex's 0.28% rise.

Market Positioning and Technical Indicators

Despite the surge in open interest, CDSL's technical indicators paint a cautious picture. The stock is trading below its 5-day, 20-day, 50-day, 100-day, and 200-day moving averages, signalling a persistent downtrend. This technical weakness is compounded by a decline in delivery volume, which fell by 8.13% to 5.5 lakh shares compared to the five-day average, suggesting waning investor conviction in holding the stock long-term.

The market cap of CDSL stands at ₹28,160.66 crores, categorising it as a small-cap stock within the capital markets sector. Its current Mojo Score is 37.0, with a Mojo Grade downgraded from Hold to Sell as of 12 January 2026, reflecting deteriorating fundamentals and market sentiment.

Interpreting the Open Interest Surge

The 12.14% rise in open interest suggests that new positions are being established in the derivatives market, indicating increased trader interest and potential directional bets. However, the mixed signals from price action and technicals imply that market participants may be divided on the stock’s near-term trajectory.

Given that CDSL is trading below all major moving averages, the open interest increase could be attributed to speculative short positions or hedging strategies rather than outright bullish bets. The relatively subdued price gain of 1.91% compared to the sector’s 2.26% advance supports this view, as does the decline in delivery volumes, which often reflects reduced long-term investor participation.

Moreover, the substantial notional value in options contracts points to active use of options strategies, possibly including protective puts or call writing, which can indicate cautious optimism or hedging against downside risk.

Liquidity and Trading Considerations

Liquidity remains adequate for sizeable trades, with the stock’s average traded value supporting a trade size of approximately ₹5.65 crores based on 2% of the five-day average traded value. This level of liquidity is favourable for institutional investors seeking to enter or exit positions without significant market impact.

However, the downgrade in Mojo Grade to Sell and the low Mojo Score of 37.0 caution investors to weigh the risks carefully. The deteriorating technical setup and falling investor participation suggest that the stock may face headwinds in the near term, despite the increased derivatives activity.

Sector and Market Context

Within the capital markets sector, CDSL’s performance has lagged behind peers, with the sector advancing 2.26% on the day compared to CDSL’s 1.91%. The Sensex’s modest gain of 0.28% further highlights the sector’s relative strength versus the broader market. This divergence may reflect sector-specific catalysts or investor rotation into other capital markets stocks with stronger fundamentals or technical momentum.

CDSL’s small-cap status and market cap grade of 3 indicate moderate size and liquidity relative to larger capital markets firms. This positioning can lead to greater volatility and sensitivity to market sentiment shifts, as evidenced by the recent open interest and volume fluctuations.

Outlook and Investor Takeaways

Investors should approach CDSL with caution given the mixed signals from derivatives activity and technical indicators. The open interest surge highlights increased market interest but does not conclusively signal a bullish trend. The downgrade to a Sell rating by MarketsMOJO reflects concerns over the stock’s near-term prospects.

Traders may consider monitoring changes in open interest alongside price movements and delivery volumes to better gauge market sentiment. The high options notional value suggests that sophisticated strategies are at play, warranting close attention to options expiry dates and strike price concentrations for clues on potential directional moves.

Overall, while the derivatives market activity points to heightened engagement, the prevailing technical weakness and falling investor participation suggest that CDSL may face continued pressure unless it can break above key moving averages and demonstrate sustained buying interest.

Summary

Central Depository Services (India) Ltd’s recent 12.14% open interest increase in derivatives reflects a surge in market positioning amid a challenging technical backdrop. The stock’s underperformance relative to its sector, combined with a downgrade to Sell and declining delivery volumes, signals caution for investors. Liquidity remains sufficient for sizeable trades, but the mixed signals from price action and derivatives activity suggest that market participants are divided on the stock’s direction. Investors should closely monitor evolving open interest trends and technical indicators before committing to new positions.
