This gain slightly outpaced the Sensex’s 0.46% rise to 35,787.64 points. The stock’s volume of 192,521 shares indicated steady investor interest as the broader market showed cautious optimism.

22 September 2026: Intraday High and Heavy Derivatives Activity

The stock surged 3.35% to close at Rs.428.40, hitting an intraday high of Rs.428.75, marking the week’s peak price. This strong performance came despite the Sensex declining 0.32% to 35,672.04 points, highlighting Coal India’s relative strength. The day saw exceptional trading volume of 619,668 shares, with a traded value of approximately ₹507.89 crores, placing it among the most actively traded stocks by value.

Notably, the derivatives market exhibited robust activity. Call options at strike prices 420, 425, and 430 saw heavy volumes, signalling bullish sentiment among traders anticipating further upside. Simultaneously, put options at the 420 strike price recorded significant volumes and turnover, reflecting hedging and cautious positioning ahead of the 29 September expiry.

Technically, the stock traded above its 5-day, 20-day, and 50-day moving averages, reinforcing short- to medium-term strength, though it remained below longer-term averages. The dividend yield remained attractive at 6.42%, supporting investor interest amid mixed market conditions.

23 September 2026: Mixed Signals with Put Option Surge and Valuation Shift

Coal India’s price retreated slightly by 1.03% to Rs.424.00, underperforming the Sensex’s 0.56% gain to 35,870.78 points. The stock experienced heavy put option activity at the 420 strike price, with 2,562 contracts traded and open interest remaining elevated. This surge in bearish derivatives positions suggested increased hedging and caution among investors despite the stock’s recent gains.

Delivery volumes surged to 83.31 lakh shares, a 132.99% increase over the five-day average, indicating heightened investor participation. The stock’s valuation metrics shifted from “very attractive” to “attractive,” with a P/E ratio of 8.46 and P/BV of 2.22, reflecting a modest re-rating amid strong relative performance. Despite this, the Mojo Score was downgraded to 57.0 with a Hold rating, signalling a more cautious outlook.

24 September 2026: Open Interest Spike Amid Price Decline

The stock declined 0.50% to Rs.421.90, marginally underperforming the Minerals & Mining sector’s 1.00% fall and the Sensex’s 1.62% drop. Open interest in derivatives surged 12.3% to 1,49,437 contracts, accompanied by robust futures and options volumes. This increase suggested active repositioning by traders, balancing directional bets and hedging strategies amid subdued price volatility.

Delivery volume rose modestly by 8.72% to 52.28 lakh shares, supporting liquidity. The stock remained above short-term moving averages but below longer-term resistance levels. The dividend yield held firm at 6.27%, continuing to attract income-focused investors despite the price softness.

25 September 2026: Open Interest Rises with Modest Price Gain to Close Week

Coal India rebounded 0.81% to Rs.425.30, outperforming the Sensex’s 0.18% gain. Open interest surged 13.5% to 1,51,268 contracts, reflecting renewed market focus and fresh capital inflows into derivatives. Despite the price gain, delivery volumes declined sharply by 53.74%, indicating reduced conviction among long-term holders.

The stock maintained its position above short-term moving averages but remained below the 100-day and 200-day averages, signalling resistance at higher levels. The high dividend yield of 6.3% continued to provide a defensive cushion for investors. The mixed technical and volume signals suggest cautious optimism as the stock consolidates near recent highs.
