Daishin Securities대신증권

Daishin Securities shares sit near their 52-week low after a customer data breach, while reported profits have fallen sharply from 2025.

Daishin Securities is a Korean brokerage and investment firm with a large balance sheet, and its stock trades at about ₩22,700, close to its 52-week low of ₩22,000 and far below its high of ₩51,400. Trailing twelve-month revenue is ₩7.57T with net income of ₩444B, and liabilities are about 8.3 times equity. The company confirmed a leak of personal data for 38,490 customers, which news reports tie to a hacking incident.

What stands out

• Trailing net income of ₩444B is well below the 2025 full-year figure of ₩187B only in relative terms; operating margin of 7.8% trails the 6.0% of 2025 but the data show revenue growth of 23.7% in 2025.
• Valuation metrics are low: P/E about 2.4, P/B about 0.2, and a dividend yield of 5.3%, but the fair value model range is very wide, from ₩4,714 to ₩41,343.
• Trailing free cash flow is negative at about -₩5.2T and borrowings are about ₩7.4T against cash of ₩2.0T, which the data do not explain further.
• Shares are down 21.2% over one year and 12.9% over one month, and foreign ownership slipped from 10.1% to 9.9% over 60 days.
• Recent filings include prospectuses and shelf registrations for derivative-linked bonds, and news coverage focuses on the breach and regulator inspections across the sector.

What to watch

• Details of the data breach, including compensation, the scope of the leak and any regulatory action, which the data do not yet describe.
• Upcoming results and whether margins and free cash flow improve from current levels.
• Whether the new bond issuance filings and the largest shareholder holding change lead to further share supply or ownership shifts.
