How the IRB Snapshot Score & forecast are built
The Downstox Snapshot Score is a transparent, rules-based read of Irb Infrastructure Developers Limited's public fundamentals plus a statistical forecast, not an analyst opinion. It rewards low-to-fair valuation, high ROE/ROCE, a strong Piotroski F-Score, a dividend, low volatility and a favourable probability of upside; it penalises rich valuations, weak capital efficiency, a low F-Score and high volatility. The price target is a 10,000-path Monte-Carlo simulation on real historical volatility, a distribution, not a single guess. The bull and bear cases are generated from the same data, so you always see both sides.
