Analysis

Guangdong Silver Age Sci & Tech Co (300221) currently trades at ¥14.10, while our model-based Fair Value estimate is ¥3.73, implying the stock looks roughly 73.6% overvalued today. The Quality Score stands at 59/100 (solid quality), in the Basic Materials 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, Guangdong Silver Age Sci & Tech Co generated revenue of 2.3B CNY at a net margin of 5.8%. Revenue grew 13.2% year over year. It earns a return on equity of 9.2%. Net debt stands at 112M CNY. Fundamentals as of Jul 9, 2026

Our scenario range runs from ¥2.53 (bear case) to ¥4.97 (bull case); at ¥14.10, 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 23% below its 52-week high and 81% above its 52-week low, currently above its 200-day average. For context, the median of 10 Basic Materials peers we cover trades at -58% fair-value upside, at -74%, 300221 screens richer 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: Multiples (¥3.97) versus Earnings-Based (¥1.94). Highest evidence: Growth DCF (80).

Frequently asked questions

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.
