Dollar-Cost Averaging (DCA) and How Deposits Get Distributed
Investing a fixed amount at regular intervals (dollar-cost averaging) helps reduce the impact of short-term market volatility, since you buy at different prices over time instead of investing a lump sum all at once.
Where should a new deposit go?
When adding new money to your portfolio, the best strategy is usually to direct it toward underweight assets (the ones that "need buying") rather than splitting it evenly — this helps rebalance the portfolio automatically without ever having to sell anything.
The tool's Deposit Calculator
The Dashboard's Deposit Calculator applies exactly this logic: it directs new deposit money to the most underweight assets first, then spreads any remainder proportionally across target weights once every asset is back in balance.
