The stock initially rose from Rs 4 to Rs 2,200, but the news spread and a rush to sell ensued, forcing a halt to trading.

News Topical, Digital Desk : The company's shares, which are part of the defense and shipbuilding sector, saw a massive decline on March 18, 2026. The selling pressure was so severe that the stock hit a lower circuit and trading was halted. Surprisingly, this same stock has surprised investors with multi-billion dollar returns in the recent past. Now, following news of the promoter's stake sale, the stock has suddenly come under pressure.

Swan Defence and Heavy Industries Ltd. shares saw a significant decline on March 18, 2026. As soon as the market opened, selling pressure increased and the stock reached the lower circuit within a short time.

The stock opened at ₹2,279.20, down from the previous trading day's closing price of ₹2,399.10. Subsequent selling pressure continued, locking the stock at ₹2,279.20. When a stock falls so sharply that it reaches the maximum limit set by the exchange, it is called a lower circuit, and trading is halted at that level. The primary reason for this decline is believed to be the promoter's stake sale plan. The company informed the exchange that its promoter company, Hazel Infra Limited (HIL), is evaluating a proposal to sell approximately 5.01% of its equity shares. This sale could be made through an offer for sale (OFS) and will be conducted through the stock exchange. The company stated that the proposal is currently in the evaluation stage and further information will be provided upon a final decision. The purpose of this potential stake sale is to meet the Minimum Public Shareholding (MPS) requirements in the company. As of December 2025, Hazel Infra is the largest promoter in the company and holds around 94.91 per cent stake.

According to regulations, promoter holdings in any listed company should not exceed a certain limit, so companies are often forced to increase public shareholding by selling stakes.

However, despite the stock's decline, the long-term returns of this stock have been astonishing.

Looking at the chart, the stock was priced at just around ₹4 in January 2025. Now, it has surpassed ₹2,200.

During this period, investors have received returns of approximately 111,080.49%, which is considered exceptional for any stock.

Regarding the company's business, Swan Defence and Heavy Industries Limited is considered India's largest shipyard and accounts for approximately 30% of the country's total shipbuilding capacity.

Located on the western coast of Gujarat, this shipyard is close to global trade routes, giving it a strategic advantage.

Spread over approximately 600 acres, this facility houses one of the world's largest dry docks, measuring 662 meters long and 65 meters wide. It can build large ships up to 400,000 DWT.

The company also has one of India's largest fabrication sites in a Special Economic Zone (SEZ), with over 2.41 million square feet of covered shed area and a capacity to fabricate 144,000 metric tons of steel annually.

The shipyard builds and repairs commercial and defense vessels, as well as offshore projects, the oil and gas sector, offshore wind farms, and heavy engineering projects.

This Swan Corp group company is positioned to play a key role in India's goal of becoming one of the top five shipbuilding nations in the world by 2047.
