006400.KS Decision Brief — research Samsung SDI before you trade it

Business quality of Samsung SDI: —/100

The latest scan has no quality score for 006400.KS yet — run the live brief to complete the full checklist free.

Important: this score measures business quality only, not whether today's price is fair. A 90+ quality stock can still be expensive enough to be a bad deal, and a 40-quality stock can be cheap enough to compensate you for the risk. That separation is exactly why the workflow treats quality and price as two different questions that only meet at the valuation ceiling.

The valuation ceiling: the price you shouldn't pay past

Working value analysis doesn't ask "will Samsung SDI grow?" It asks "what does ₩569,000 already assume?" Our two-stage residual-income model turns those assumptions into a single ceiling number. Below the ceiling you are paying a discount; above it you are paying for hope. Neither is automatically wrong — the point is knowing which one you're doing.

How to read the LONG signal on 006400.KS

• Status: LONG — the timing engine saw a constructive structure pass its criteria as of scan 2026-08-27.
• Age: 280 bars — an aging signal: the original reason may have expired, so run a fresh brief before relying on it.
• uPnL +207.1% · total return +207.1% — cumulative performance of the signal inside our system. It measures how the engine has behaved historically, not a forecast for you.

The right order: quality passes first → the ceiling is acceptable → thesis breaks are written down → then look at the signal. Looking at the signal first and hunting for reasons afterward is confirmation bias, and it gets everyone.

What would break the Samsung SDI thesis (a template for Batteries)

Before investing real money, write your own break-conditions down. Common templates analysts use for Batteries names:

1. Core revenue contracts for two quarters without a seasonal explanation
2. The margin premium that defined the moat gets closed by rivals
3. Net debt versus operating cash flow deteriorates steadily
4. Key executives or the founding team exit together

The point is not the list above — it's that you write yours before buying. Conditions written while you own nothing are always colder than conditions written while you are down.
