StockValuation Pro 1 is designed to bridge this gap by equipping investors, financial advisors, and investment clubs with professional-grade Discounted Cash Flow (DCF) analysis, equity analysis, and portfolio management tools. The platform supports multiple valuation methodologies—such as P/E, P/S, EV/EBITDA, and P/FCF ratios—alongside customizable five-year revenue and margin projections for bull, base, and bear scenarios. Unlike conventional spreadsheets or static portfolio trackers, StockValuation Pro emphasizes fundamental financial modeling, realtime data integration, and clear valuation metrics to guide disciplined investment decisions. Developed as a modern webbased financial application using React, TypeScript, and Tailwind CSS for the frontend, and Supabase with PostgreSQL for secure backend infrastructure, it incorporates the Finnhub API for live market data and Recharts for interactive analytics. This paper outlines the platform’s features, valuation methodology, technical architecture, and potential role in democratizing access to professional-grade investment analysis within the broader FinTech ecosystem.

INTRODUCTION Over the past decade, individual investors have gained unprecedented access to financial markets. However, with the proliferation of investment tools, data sources, and platforms, making informed and disciplined investment decisions has become both more critical and more complex. The rise of algorithmic trading, speculative retail activity, and real-time news cycles has created an environment in which long-term, value-driven investing often gets overshadowed by short-term noise. In response to this complexity, there has been a growing demand for platforms that can offer structured, data-driven frameworks to guide investment decisions based on fundamental principles. Among the most widely accepted frameworks is Discounted Cash Flow (DCF) analysis, which helps investors assess a company’s intrinsic value by forecasting future cash flows and discounting them to present value. Despite its importance, performing DCF calculations has traditionally required either spreadsheets or expensive enterprise software, making it inaccessible to many. 1 https://ubiquitous-medovik-3395a4.netlify.app StockValuation Pro addresses this gap by providing an intuitive, yet analytically rigorous, web-based application that enables users to perform DCF analysis, maintain watchlists, and monitor portfolio performance in real time. The platform is built with a user-centric interface and leverages real-time data feeds to empower investors to make decisions aligned with long-term value investing philosophies. The purpose of this paper is to outline the features, technical architecture, and intended audience of StockValuation Pro, while emphasizing its contribution toward democratizing financial modeling and portfolio management.  Demo Access A working version of StockValuation Pro is available at: https://ubiquitous-medovik-3395a4.netlify.app The platform supports real-time usage of all described features and is regularly updated via CI/CD pipelines connected to GitHub.
