mywealthxray.com was created to solve a widespread problem in Indian retail investing: the illusion of diversification. Millions of investors diligently build systematic investment plans (SIPs) across 5 to 10 mutual funds, assuming each fund brings new diversification. In practice, due to regulatory constraints and benchmark-tracking pressures, many popular equity schemes hold nearly identical baskets of underlying companies.
Who We Are: The Research Desk
We are independent analytical developers and quantitative researchers focused on Indian market structure, AMC disclosures, and portfolio construction mathematics. Founded and maintained by Satya (@satyadev30), we do not sell mutual fund schemes, distribute financial products, or collect distributor commissions. Our sole focus is producing mathematically rigorous, unbiased tooling and empirical research for retail investors.
Why Portfolio Overlap Analysis Matters
In India, guidelines mandated by SEBI (the Securities and Exchange Board of India) require specific fund categories to allocate a minimum percentage of their assets into designated market-cap tiers. For example, active Large Cap funds must invest at least 80% of their total assets into the top 100 stocks listed on the National Stock Exchange (NSE) and Bombay Stock Exchange (BSE).
Because the large-cap universe is legally confined to only 100 companies, fund managers from different AMCs inevitably pick from the exact same pool. Holding three or four active large-cap or flexi-cap funds often creates 50% to 75% stock overlap. When this happens, investors end up paying multiple active fund management fees (Total Expense Ratios ranging from 0.70% to 1.80%) for what is practically an index fund mirror with concentrated single-stock risk.
Data Pipeline & Verification Standards
Our platform operates an automated data ingestion pipeline designed for accuracy and integrity:
- Statutory Source Disclosures: We ingest monthly full portfolio disclosures directly from Asset Management Company (AMC) statutory filings as mandated by SEBI regulations.
- Deterministic Security Resolution: Every equity holding is mapped deterministically using canonical ISIN (International Securities Identification Number) codes to prevent name-alias ambiguities across AMC sheets.
- Arbitrage & Derivative Guardrails: Directionally hedged equity positions in Arbitrage funds are isolated so users don't receive false-positive overlap alarms against directional equity funds.
- Direct-Growth Standardization: Schemes are standardized to canonical Direct-Growth plans. Because Direct and Regular plans share identical underlying stock portfolios and fund management, this eliminates redundant entries while keeping calculations clean.
Key Metrics We Track
- Pairwise Stock Overlap: The exact percentage of common capital shared between any two mutual fund schemes.
- Effective Number of Stocks (ENS): Derived from the Herfindahl-Hirschman Index (HHI) to measure your portfolio's true diversification, revealing where capital is genuinely concentrated.
- Consolidated Sector Allocation: Aggregated industry exposure across Banking, IT, Pharma, Energy, and other sectors to highlight unintended macro sector bets.
- Expense Ratio Drag: Weighted fee analysis showing the total cost of holding overlapping active schemes.
