Evaluating 17 Leading U.S. Tech Companies with a Groundbreaking Forward-Looking Return Metric: SIRRIPA[Évaluation de 17 entreprises technologiques américaines les plus proéminentes à l’aide d’un indicateur révolutionnaire de rendement prospectif : le SIRRIPA]

This article presents a comprehensive valuation of 17 of the most influential U.S. technology companies using a groundbreaking metric called SIRRIPA (Stock Internal Rate of Return Including Price Appreciation). As traditional valuation models struggle to rationalize the pricing of high-growth firms—especially in the era of artificial intelligence—SIRRIPA offers a forward-looking, risk-adjusted return metric derived from the Potential Payback Period (PPP). This framework enables direct comparison of stocks with bonds, benchmarking against the risk-free rate, and sensitivity analysis to interest rates and earnings growth. By applying SIRRIPA to companies including NVIDIA, Microsoft, Amazon, and Palantir, the analysis uncovers meaningful insights into internal return potential, reveals over- and undervaluation relative to fundamentals, and demonstrates how SIRRIPA uniquely rationalizes even extreme valuations. The results not only validate SIRRIPA's practical power but highlight its role as a new standard for modern equity valuation.
