Analysis

Cubic Sensor and Instrument Co (688665) currently trades at ¥46.55, while our model-based Fair Value estimate is ¥24.59, implying the stock looks roughly 47.2% overvalued today. The Quality Score stands at 60/100 (solid quality), in the Technology sector. Bear case: priced above our estimate, the market already discounts strong expectations. Bull case: above-average quality can justify a premium, the entry price still matters most (evidence: high).

Over the trailing twelve months, Cubic Sensor and Instrument Co generated revenue of 1.0B CNY at a net margin of 12.9%. Revenue grew 4.1% year over year. It earns a return on equity of 11.5%. Net debt stands at 6.5M CNY. Fundamentals as of Jul 12, 2026

Our scenario range runs from ¥14.35 (bear case) to ¥30.76 (bull case); at ¥46.55, the current price sits above that range. Bear and bull are the same models run on conservative and optimistic assumptions (margins, growth, valuation multiples), so a plausible valuation range, not a price target. The share trades about 35% below its 52-week high and 19% above its 52-week low, currently below its 200-day average. For context, the median of 10 Technology peers we cover trades at -73% fair-value upside, at -47%, 688665 screens cheaper than that median.

Fair Value models

Each model estimates fair value its own way; the Fair Value above is the evidence-weighted blend. Evidence (0–100) measures how completely this model’s inputs are available: well-fed models carry more weight in the blend. The spread across models is intentional, each one stresses a different value driver; dividend models, for instance, come out structurally low when payout is small.

Widest divergence: Growth Earnings (¥41.18) versus Dividend Discount (¥6.05). Highest evidence: Growth DCF (80).

How we calculate Fair Value

Each company is valued through a stack of independent intrinsic-value models (DCF variants, residual-income, multiples and more), blended into one family-balanced consensus and weighted by how much trustworthy data backs it. A separate quality layer scores the fundamentals. Every input is real reported data, nothing guessed.
