Your journey
as an INFORMED investor

ETF Insider is a novel data visualization and analytics tool for retail investors to gain insight into portfolio compositions, concentration risks, portfolio efficiency and much more.

Portfolio visibility to identify fund and asset overlap

portfolio visibility

ETF Insider is a tool to easily breakdown and visualize overlap between multiple ETFs and Mutual Funds and to identify how much of any single asset is held within a portfolio of overlapping funds.
Index funds are often highly weighted for the same large cap growth stocks in the USA. This may give the illusion of a highly diversified portfolio. For example, the 7 largest stocks in the S&P 500 account for 25% of the index - All of which are in a single sector.


Concentration risks come in many forms, which can cause investors to be exposed to significant losses in the event something happens in their area of concentration. The risk may be geographical, sectoral or simple over exposure to a small subset of individual stocks. With ETF Insider, investors can identify their real world exposures and diversification across sectors, geographies, cap sizes, and market types.

portfolio efficiency

At its core, investment is a balance of risk and reward - For every level of risk investors should be appropriately compensated with returns, if they aren't then the portfolio is inefficient and should be optimized.
Using Modern Portfolio Theory (MPT), ETF Insider can calculate and graph the efficiency of different portfolio compositions and allocations to find the optimal point of risk to reward.
