21 September 2026: Opening the Week with a Decline

Ather Energy began the week at Rs.1,593.50, down 1.02% from the previous close. This decline contrasted with the Sensex’s 0.46% gain to 35,787.64, signalling early weakness in the stock. The volume was moderate at 123,648 shares, indicating cautious investor participation. The stock’s underperformance relative to the broader market set the tone for the week ahead.

22 September 2026: Surge in Open Interest Amid Mixed Price Action

On 22 September, Ather Energy experienced a significant 13.37% increase in open interest in its derivatives segment, rising from 40,212 to 45,587 contracts. This surge accompanied a 3.16% decline in the stock price to Rs.1,543.10, underperforming the Sensex’s 0.32% drop. The total traded volume in derivatives was robust, with futures valued at approximately ₹30,185.47 lakhs and options at ₹22,302.31 crores.

The weighted average price of traded contracts skewed towards the day’s low, suggesting bearish sentiment despite the increased market activity. The stock traded within a narrow intraday range, closing near the lower end, reflecting short-term selling pressure. Delivery volumes fell by 43% compared to the five-day average, indicating reduced conviction among long-term holders.

23 September 2026: High Value Trading and Heavy Put Option Activity Amid Continued Declines

The stock continued its downward trajectory on 23 September, closing at Rs.1,499.80, down 2.81% on the day and marking a third consecutive session of losses. Despite this, Ather Energy was among the most actively traded equities by value, with a volume of 19,05,599 shares and a traded value of ₹28,721.38 lakhs. This high liquidity underscores sustained investor interest amid the sell-off.

Put option activity surged significantly, with 3,074 contracts traded at the ₹1,500 strike price expiring on 29 September. The turnover for these puts was approximately ₹33.52 crores, reflecting increased bearish positioning and hedging. The open interest for these puts stood at 1,308 contracts, signalling that many traders were either initiating or maintaining protective bearish bets.

Technically, the stock remained above its 50-day, 100-day, and 200-day moving averages, suggesting some longer-term support. However, it traded below its 5-day and 20-day averages, confirming short-term weakness. The narrow intraday range and weighted average price near the session low further indicated selling pressure dominating the day.

24 September 2026: Stabilisation Amid Market Volatility

On 24 September, Ather Energy’s price remained almost flat, closing at Rs.1,499.40, down a marginal 0.03%. The Sensex, however, declined sharply by 1.62% to 35,291.38, indicating broader market weakness. The stock’s volume was moderate at 382,751 shares, suggesting some consolidation after the prior days’ declines. The narrow trading range and minimal price change may reflect investor indecision amid ongoing sector challenges.
