5-year analysis
As of August 13, 2025, the firm's stock opened at KRW 1,638 (USD 1.26), marking a 3.9 per cent decline from KRW 1,705 (USD 1.31) on the same date in 2024. This reflects a continuing downward trend over the recent year.
Going further back, on August 11, 2023, the stock was priced at KRW 3,005 (USD 2.31), representing a sharp decline of approximately 45.5 per cent from that level to today's price. On August 12, 2022, the stock stood at KRW 2,290 (USD 1.76), which indicates a steady decrease over the past three years. Adding to the longer-term perspective, on August 13, 2021, the stock traded lower than today's value, around KRW 1,277 (USD 0.98).
This sustained decline highlights persistent challenges faced by the company, including market volatility, sector-wide pressures, and potential company-specific issues such as operational performance or strategic execution. However, the more moderate drop between 2024 and 2025 suggests the pace of decline may be slowing, possibly indicating stabilisation or the early signs of recovery.

Year-on-year revenue history
Choil Aluminum's recent financial data reveals a significant recovery in earnings alongside stable revenue generation. As of March 31, 2025, the company reported revenues of KRW 507.7 billion (USD 390 million) and profits of KRW 16.8 billion (USD 12.9 million), marking a notable improvement from the previous quarters.

Throughout 2024, the company's revenue fluctuated slightly, ranging from KRW 478.4 billion (USD 368 million) in March to just under KRW 498.5 billion (USD 383 million) in June and December, while earnings showed a strong upward trend from KRW 2.9 billion (USD 2.23 million) in March to KRW 10.9 billion (USD 8.38 million) by December.
The company faced some earnings challenges in 2023, with negative earnings reported for three consecutive quarters, reaching a low of KRW -11.0 billion (-USD 8.46 million) in June 2023 despite relatively consistent revenues above KRW 465 billion (USD 357 million).
