IndexGuard

IndexGuard is a mobile + web app (traditional + AI) that audits your index-fund portfolio for overlap, hidden costs, and unintended bets. Most DIY investors own multiple ETFs/mutual funds that quietly duplicate the same mega-cap stocks, concentrate sector risk, and create a false sense of diversification. Connect your brokerage via read-only sync, then IndexGuard breaks down true exposure by company, sector, country, and factor (value/growth, size, momentum proxies). It flags “closet indexing” (high fees for index-like exposure), tax-inefficient fund placement (taxable vs IRA), and drift from your target allocation. The AI layer explains findings in plain English and generates a simple action plan (e.g., consolidate to 2–4 funds, reduce overlap, keep costs low) without pretending to predict returns. It also tracks changes over time and alerts you when new purchases reintroduce overlap or concentration.
