InvestResearch Analytical Studies & Whitepapers
Rigorous mathematical evaluations of Indian mutual fund expense drag, direct equity valuation, and taxation laws.
Quantitative Methodology & Mathematical Conventions
InvestResearch India computes all performance metrics using decimal.js with precision 28 to eliminate floating-point rounding errors. Category classifications adhere strictly to SEBI circulars (SEBI/HO/IMD/DF3/CIR/P/2017/114). Risk-adjusted metrics (Sharpe Ratio, Sortino Ratio, Jensen's Alpha) are benchmarked against a baseline risk-free rate (Rf) of 6.50% p.a. (proxying the 91-Day Government of India Treasury Bill). Portfolio holding returns are date-exact Newton-Raphson XIRR simulations. All studies are educational analytics and do not constitute personalized investment advice.
