Chemical and Ammunition Stocks Surge 5% After Earnings Shock, Market Cap Increases by $200 Million in a Day

On March 20, US chemical and ammunition manufacturer Olin Corp (NYSE: OLN) saw its shares surge 5.25%, closing at $27.46 in New York. Trading volume topped 1.83 million shares, lifting its market capitalization by about $170 million to roughly $3.1 billion (around 4 trillion KRW) in a single day.

The company had previously disclosed an expected net loss of about $100 million in 2025 and potential litigation-related payments of up to $185 million in the first half of 2026. In February, Olin amended its 2025 loan agreements to bolster liquidity management.

In March, Citi raised its price target for Olin from $21 to $26, citing a potential industry recovery and helping to improve investor sentiment.

Olin specializes in chlor-alkali, epoxy resins and Winchester-brand ammunition. As a US specialty-chemicals and ammunition producer, its performance is highly sensitive to industrial demand and economic cycles.

Recently, the company has been pursuing both restructuring and profitability recovery through portfolio adjustments, including the closure of its Brazilian facility and the reorganization of its epoxy business.
