Cholamandalam Investment Sees Sharp Open Interest Surge Amid Mixed Price Action

Open Interest and Volume Dynamics

On 18 February 2026, CHOLAFIN’s open interest (OI) in futures and options contracts rose sharply from 34,399 to 39,395 contracts, an increase of 4,996 contracts or 14.52%. This surge in OI was accompanied by a futures volume of 19,565 contracts, reflecting active participation in the derivatives market. The futures value stood at ₹1,24,540.63 lakhs, while the options segment exhibited an enormous notional value of ₹85,83,83,1043 lakhs, underscoring the scale of trading interest.

The total combined derivatives value reached ₹1,25,152.69 lakhs, with the underlying stock price at ₹1,692. This level of open interest growth, coupled with substantial volume, suggests that market participants are either establishing new positions or reinforcing existing ones, potentially anticipating significant price movements in the near term.

Price Performance and Market Context

Despite the open interest surge, CHOLAFIN’s stock price underperformed its sector, declining by 1.84% on the day against the NBFC sector’s 0.85% fall and the Sensex’s 1.12% drop. The stock has been on a two-day losing streak, falling 2.51% cumulatively. Notably, the stock trades above its 20-day and 200-day moving averages but remains below the 5-day, 50-day, and 100-day averages, indicating a mixed technical picture with short-term weakness amid longer-term support.

Investor participation has risen sharply, with delivery volume on 18 February reaching 10.45 lakh shares, an 81.23% increase over the five-day average. This heightened delivery volume signals stronger conviction among investors, possibly reflecting accumulation or repositioning ahead of anticipated corporate or sector developments.

Market Positioning and Directional Bets

The increase in open interest alongside rising volume often points to fresh directional bets. In CHOLAFIN’s case, the 14.5% OI increase suggests that traders are actively positioning for a potential price move, though the recent price decline indicates some short-term caution. The derivatives data does not explicitly reveal whether the new positions are predominantly long or short; however, the combination of rising OI and falling price can imply that fresh short positions are being built or that longs are unwinding.

Given the stock’s liquidity—capable of supporting trade sizes up to ₹3.82 crore based on 2% of the five-day average traded value—market participants can execute sizeable trades without significant price disruption. This liquidity, combined with the large market capitalisation of ₹1,43,543.74 crore, positions CHOLAFIN as a key NBFC large-cap stock attracting institutional and retail interest alike.

Fundamental and Technical Assessment

Cholamandalam Investment & Finance holds a Mojo Score of 71.0, reflecting a strong Buy rating upgraded from Hold on 13 January 2026. This upgrade was driven by improved earnings visibility, asset quality metrics, and a favourable sector outlook. The company’s market cap grade is 1, indicating a large-cap status with stable market presence.

Technically, the stock’s position above the 20-day and 200-day moving averages suggests underlying strength, despite short-term pressure from the 5-day and 50-day averages. The recent decline in price, coupled with rising delivery volumes, may indicate a consolidation phase before a potential breakout. Investors should monitor the stock’s ability to reclaim the 5-day moving average as a sign of renewed momentum.

Sector and Market Comparison

Within the NBFC sector, CHOLAFIN’s performance has been relatively resilient. While the sector index fell 0.85% on the day, the stock’s 1.84% decline is slightly steeper but not disproportionate given broader market volatility. The Sensex’s 1.12% drop reflects a cautious market environment, possibly influenced by macroeconomic factors such as interest rate expectations and credit growth concerns.

Investors should consider CHOLAFIN’s derivatives activity in the context of sector trends, where rising open interest in NBFC stocks often precedes sector rotation or re-rating phases. The company’s strong fundamentals and liquidity profile make it a preferred choice for investors seeking exposure to the NBFC space with a large-cap safety net.

Implications for Investors and Traders

The surge in open interest and volume in CHOLAFIN’s derivatives signals increased market attention and potential volatility ahead. Traders should watch for confirmation of directional bias through price action and volume trends in the coming sessions. A sustained rise in price accompanied by further OI growth would validate bullish positioning, while continued price weakness with rising OI might indicate short accumulation or hedging activity.

Long-term investors may view the recent dip as a buying opportunity, given the company’s strong fundamentals, large-cap status, and sector tailwinds. However, caution is warranted amid broader market uncertainties and the stock’s mixed technical signals. Monitoring delivery volumes and moving average crossovers will be key to assessing the sustainability of any trend reversal.

Conclusion

Cholamandalam Investment & Finance Company Ltd’s recent open interest surge in derivatives highlights a pivotal moment of market repositioning. While the stock has experienced short-term price softness, its robust fundamentals, liquidity, and upgraded Mojo Grade to Buy underpin a positive medium-term outlook. Investors and traders should remain vigilant to evolving market signals, balancing technical cues with fundamental insights to navigate this large-cap NBFC’s next phase.
