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, which lays out the evidence and the philosophy. Everything else in the cluster is implementation detail.
