# DCA Value

> DCA Value is an educational website for comparing dollar-cost averaging, value averaging, and threshold-based portfolio rebalancing with historical market data.

DCA Value simulations and reports describe historical results, not forecasts or investment recommendations. Results depend on the selected asset, dates, price convention, contribution schedule, and strategy settings. Fees, taxes, spreads, slippage, custody costs, and personal constraints are excluded unless a page states otherwise.
