Analysis
Prostarm Info Systems Limited (PROSTARM) currently trades at ₹135.96, while our model-based Fair Value estimate is ₹81.01, implying the stock looks roughly 40.4% overvalued today. The Quality Score stands at 36/100 (below-average quality), in the Industrials 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: medium).
Over the trailing twelve months, Prostarm Info Systems Limited generated revenue of ₹3.9B at a net margin of 8.6%. Revenue grew 27.4% year over year. It earns a return on equity of 16.9%. Net debt stands at ₹909M. Fundamentals as of Aug 13, 2026
Our scenario range runs from ₹60.76 (bear case) to ₹101.26 (bull case); at ₹135.96, 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 46% below its 52-week high and 19% above its 52-week low, currently below its 200-day average. For context, the median of 10 Industrials peers we cover trades at -65% fair-value upside, at -40%, PROSTARM 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.
