VaR

4.16%
[2.62%, 7.59%] · As of 2026-10-01
VaR by window

The headline's measure for each of the three windows on one scale, the dot being the estimate and the bar its interval. The windows are nested and share their observations, so the three readings are not three independent measurements. The selected window is highlighted.

Daily return distribution

The issue's daily returns over the chosen window counted into equal-width bins. The vertical lines mark the VaR and cVaR above on the loss side. The published VaR sample applies exclusion rules for halts and first sessions that this raw daily series does not, so the bars and the marks can differ slightly at the edges.

Drawdown

Deepest drawdown 56.4% (2026-07-29). How far below its previous peak the issue stood each day over the chosen window, a description of the path already travelled.

252-day rolling beta

A 252-day window rolled one day at a time over the longest daily span of the characteristic line. It shows when the beta against the KOSPI200 and the annualized volatility of the issue's excess return rose and fell, and unlike the headline figures above it carries no interval.

252-day rolling annualized volatility

Each point is one period's index excess return and issue excess return, and the line is the regression fitted to those points. The risk-free rate is the certificate of deposit rate.

This diagram traces where revenue goes at each step on its way to net income, using the filed amounts as they are. The non-operating result is taken as the difference between profit before tax and operating income and is shown as income or expense by its sign, and whatever a step's items leave unexplained is shown separately as other.

Debt ratio%

The left bar splits assets into current and non-current and the right bar splits the financing of those assets into liabilities and equity, so the two bars stand at the same height.

Quarterly resultsKRW 100M

Year-on-year growth%

Each quarterly bar is that quarter's three months and is never mixed with an annual figure. The growth rate is computed only where the same quarter a year earlier is also shown here, and is left blank when the base was a loss.

Cash conversion cycledays

Free cash flow breakdownKRW 100M

Inventory days and receivable days stack upward, payable days hang downward, and the cash conversion cycle they net to is drawn as the line. Each day count uses the average balance with the prior year, so the oldest year is not drawn. A day count whose line was not filed is left out, and the cycle is shown only for years that carry all three.

Free cash flow is cash from operating activities less spending on property, plant and equipment, and all three bars keep the sign as filed.

ROE%

ROE is the product of the owners' net margin, asset turnover and financial leverage. All three use period-end balances as denominators, and profit and equity are on the owners' basis, so the product matches the ROE in the table.

The auditor's name and the opinion are transcribed verbatim from the filed audit report, and the wording follows the filer. A fiscal year shown twice means the filing carried two entries that the source does not distinguish.

Korean audit opinions come in four kinds, where an unqualified opinion (적정) finds the statements fairly presented, a qualified opinion (한정) does so except for a stated matter, an adverse opinion (부적정) finds them not fairly presented, and a disclaimer of opinion (의견거절) means the auditor could not obtain enough evidence to form a view.

Valuation

Valuation multiplesx

PER and PBR divide each period's closing price by the per-share figure filed for that same period, and a loss period is left blank. The quarterly view is a multiple of quarterly EPS.

Dividend historyKRW

The dividend-per-share bars are restated onto the current share basis for splits and par-value changes. The payout ratio and the dividend yield divide figures filed for the same period and are left unadjusted.

Payout ratio and dividend yield%

PER bandKRW

The price is the adjusted close and each band line multiplies the EPS of the latest completed fiscal year by a fixed multiple. The previous year's EPS stays in force until the next fiscal year ends, and the multiples divide the range between the lowest and highest annual PER on record into equal steps.

Each fiscal year's figures use that year's accounts and the treasury yield at its period end, with beta held at its current value, and splits or par changes are restated to the current share basis.

How the figures are calculated

Each model's formula is shown in symbols and then with this issue's own numbers substituted, step by step. Changing a value in the assumptions panel changes the numbers here too. Firm-level amounts are in hundred million won and per-share values in won.

Cost of equity

r=rf+β×ERPr = r_f + \beta \times \mathit{ERP}

r = 4.40% + 0.57 × 5.00% = 7.24%

Initial growth

g1=max⁡{ROE×(1−payout), 0},gt=g1+(gT−g1) t−1N−1g_1 = \max\{\mathit{ROE} \times (1 - \text{payout}),\,0\},\qquad g_t = g_1 + (g_T - g_1)\,\frac{t-1}{N-1}

g_1 = max(7.09% × (1 − 46.99%), 0) = 3.76%

Growth starts at this value in the first year and falls by equal steps each year to reach the terminal rate in the fifth

Gordon growth model

P0=D0 (1+gT)r−gTP_0 = \frac{D_0\,(1 + g_T)}{r - g_T}

P_0 = 20,000 × (1 + 2.00%) / (7.24% − 2.00%) = 20,400 / 0.0524 = 389,096 KRW

The cost of equity is the risk-free rate plus beta times the equity risk premium. Initial growth is the newest fiscal year's return on equity times its retention ratio, floored at zero, and falls by equal steps from that value in the first year to the terminal rate in the fifth. Only the Gordon model grows at the terminal rate from the start. Discounted cash flow starts from operating cash flow less capital expenditure, where FCFF adds after-tax interest paid and discounts at the weighted average cost of capital, and FCFE adds net borrowing and discounts at the cost of equity. The residual income model adds to book value per share the present value of earnings above the equity charge.
