What matters now
The price sits above even our optimistic bull case (¥16.34). The favourable scenario is already priced in.
The large gap to fair value rests on thin data (low evidence): fewer applicable models and a shorter history. Read it with extra caution.
Solid but not exceptional quality (56/100) and above fair value, neither a clear bargain nor a standout compounder.

How to read this chart
60‑month range ¥12.75 – ¥155.87 · fair‑value band ¥9.40 – ¥16.34 · the ¥112.89 price screens above the ¥13.11 fair value. Dashed = 300-day average. As of Aug 17, 2026.
Beijing Worldia Diamond Tools Co Ltd (688028) currently trades at ¥112.89, while our model-based Fair Value estimate is ¥13.11, implying the stock looks roughly 761.3% overvalued today. The Quality Score stands at 56/100 (solid quality), in the Industrials sector. Bull case: the DCF Models group reads highest at a median of ¥16.14 per share, and 0 of the 26 models we run sit above the ¥112.89 price. Bear case: the Dividend Discount group reads lowest at ¥5.77, and 26 of the 26 models stay below the price. Evidence for this calculation is low.
Over the trailing twelve months, Beijing Worldia Diamond Tools Co Ltd generated revenue of 797M CNY at a net margin of 12.8%. Revenue grew 27.9% year over year. It earns a return on equity of 5.1%. The balance sheet holds a net cash position of 214M CNY. Fundamentals as of Aug 17, 2026
Scenario range: ¥9.40 (bear) to ¥16.34 (bull), the price of ¥112.89 sits above it. Bear and bull are the same models on cautious and optimistic assumptions, a range, not a price target. The share trades about 20% below its 52-week high, currently above its 200-day average. For context, the median of 10 Industrials peers we cover trades at −35% fair-value upside, at −88%, 688028 screens richer than that median.

Non-valuation factor families (profitability, growth, cashflow, financial strength, momentum …), each academically grounded. Valuation itself sits in the Fair Value and is deliberately excluded here to avoid double-counting.
All values are scores from 0 to 100 (100 = best against fixed, research-based bands), not percentages. The three market factors (momentum, 52-week proximity, low volatility) are displayed but carry zero weight in the headline number: market sentiment is not a business property.
