LowCostIndexFundInvesting Hub

The case for low-cost index funds is one of the most thoroughly evidenced claims in finance: a passively-managed fund that tracks a broad market index, held over decades, will outperform the majority of actively-managed alternatives — net of fees, after taxes, on a risk-adjusted basis. This cluster is the working set on how to do that.

The canonical entry point is [LowCostIndexFundInvesting](LowCostIndexFundInvesting), which lays out the evidence and the philosophy. Everything else in the cluster is implementation detail.
