Analysis
Ruttonsha International Rectifier Ltd (517035) currently trades at ₹170.55, while our model-based Fair Value estimate is ₹91.24, implying the stock looks roughly 46.5% overvalued today. The Quality Score stands at 23/100 (below-average 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, Ruttonsha International Rectifier Ltd generated revenue of ₹266M at a net margin of 0.6%. Revenue declined 70.9% year over year. Net debt stands at ₹104M. The stock trades on a trailing P/E of 146.2 (as of Jul 4, 2026). Fundamentals as of Aug 13, 2026
Our scenario range runs from ₹67.05 (bear case) to ₹115.42 (bull case); at ₹170.55, 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 56% below its 52-week high and 29% above its 52-week low. For context, the median of 10 Technology peers we cover trades at -21% fair-value upside, at -47%, 517035 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.
All 16 models by family
Widest divergence: Growth Earnings (₹312.99) versus Dividend Discount (₹25.08). Highest evidence: Residual Income (76).
