Build Your Own Index Fund - the Analysis Tool, Without the Brokerage
You want the discipline of an index without paying a fund to pick for you. Indexes lets you weight your own basket, backtest it against real history, and follow it against a benchmark, all as analysis, without ever placing a trade.
Educational only · Never places a trade
In short
To build your own index fund with Indexes, you choose the holdings you believe in, set a weight for each, and name the basket. Indexes then backtests that weighting against real historical market data, showing hypothetical historical performance next to a benchmark like the S&P 500 so you can see how the rules would have behaved. Once you are satisfied, you track the index over time and watch it move against that benchmark day by day. Indexes is an analysis tool, not a fund and not a brokerage: there is no account minimum, no money changes hands, and no trade is ever placed. It is informational and educational only, never investment advice, and it is globally accessible because it analyzes rather than transacts. Past performance does not guarantee future results, and a backtest is a hypothetical illustration of the past, not a prediction.
Why it fits
Self-directed investors who want the structure of an index they define themselves, backtested and tracked as analysis, without a fund or a brokerage account.
Your weights, your rules
Pick the holdings and set each weight yourself, equal-weight or conviction-weighted, and Indexes treats the whole basket as one index you can name and follow.
Backtested against real history
See how your weighting would have behaved against real market data as hypothetical historical performance, next to a benchmark, so the rules are tested before you commit to watching them.
Analysis, not a brokerage
Indexes never places a trade, connects to a broker, or holds money. There is no account minimum, and it works anywhere because it studies the market rather than transacting in it.
Questions
Build your own index fund, answered
Can I really build my own index fund without a brokerage account?
Yes, because Indexes only analyzes. You choose holdings and weights, and the tool backtests and tracks the resulting index, but it never places a trade or opens a brokerage relationship, so there is no account minimum and no money changes hands.
How is this different from just buying an ETF?
An ETF is a fund someone else already built and weighted. Building your own index fund with Indexes means you choose the holdings and the weights yourself, then backtest and track that exact combination rather than accepting a fund manager's rules.
Does building my own index fund mean I have to rebalance it myself?
Indexes shows you how a given weighting would have behaved, including through periods where it drifted from its original weights, so you can decide your own rebalancing rule. It is analysis, not an automated rebalancing service.
Build your index and see how it backtests
Bundle stocks or crypto into your own weighted index, backtest it against real market history, and track it against the S&P 500 or BTC. Indexes is educational and informational only, and it never places a trade.
