Market Network: How Stocks, ETFs and Indices Connect

A portfolio is rarely a list. Buy two broad ETFs and you own the same twenty companies twice; buy a sector fund on top and the concentration you were avoiding gets worse. This page draws the connections we actually measure — no editorial judgement, no recommendations.

How to read it. A line means a relation we can point at: a fund holds a stock, a fund tracks an index, an index contains a name, a stock sits in a sector or a country, two funds overlap by weight, two stocks reach a portfolio through largely the same funds (similar ETF exposure). Circle size is the number of connections, nothing else — it is not size, quality or return.
