Sunil Singhania’s Abakkus Investment Managers acquired a 1.48% stake in Zinka Logistics Solutions (BlackBuck) on September 11, 2026. Simultaneously, promoters of Jamna Auto Industries sold a 5% stake, which was fully absorbed by major institutional buyers including 360 ONE and DSP Mutual Fund.
The Indian stock market witnessed significant institutional movement on September 11, 2026, driven by notable transactions in the logistics and automotive components sectors. Market veteran Sunil Singhania’s Abakkus Investment Managers increased its exposure to the logistics sector by acquiring a 1.48% stake in Zinka Logistics Solutions, the parent company of BlackBuck. This acquisition involved approximately 27 lakh shares purchased at Rs 576.05 per share, amounting to a total investment of roughly Rs 155.5 crore. The shares were offloaded by Accel India IV (Mauritius). Following the announcement of this institutional entry, Zinka Logistics shares rose 7.21% to close the trading session at Rs 628.15.
Promoter Activity in Jamna Auto
In a separate development, promoters of Jamna Auto Industries, Randeep Singh Jauhar and Pradeep Singh Jauhar, exited a 5% stake in the automotive suspension manufacturer. The promoters offloaded a combined 99.95 lakh shares each, totaling a transaction value of approximately Rs 255.87 crore. The shares were traded at Rs 128 per share. While promoter stake sales are often viewed by investors as a monitorable event that can signal a reduction in long-term confidence or personal liquidity needs, the market absorbed this supply rapidly due to strong interest from institutional buyers.
Institutional Absorption
The bulk of the shares sold by the Jamna Auto promoters were immediately picked up by institutional investors, which helped maintain price stability. 360 ONE Mutual Fund and 360 ONE Asset Management were the largest buyers, securing a 2.5% stake for Rs 127.93 crore. DSP Mutual Fund also participated, acquiring a 1.95% stake worth Rs 100 crore, while the Abu Dhabi Investment Authority (ADIA) purchased a 0.54% stake for Rs 27.93 crore. This immediate institutional support suggests that despite the promoter exit, large investors continue to see value in the company’s business model. Jamna Auto shares closed at Rs 135.46 on September 11, recording a 2.73% gain and marking the fifth consecutive day of the stock's upward trend.
For investors, these transactions highlight how institutional activity can act as a counterbalance to promoter divestment. While the entry of investors like Abakkus into Zinka Logistics reflects confidence in the growth trajectory of the logistics platform, the Jamna Auto event serves as a reminder that institutional demand is a critical factor when promoters decide to reduce their holdings. Shareholders may continue to track whether this institutional buying helps sustain the current price trends in the coming weeks.
