Dollar-cost averaging means investing a fixed amount on a regular schedule. The same contribution buys more shares when prices are lower and fewer when prices are higher.
Automation changes behavior
A schedule can prevent every scary headline from becoming a fresh decision. That consistency is valuable for money earned and invested over time.
It does not make the underlying investment safe.
A lump sum is a different question
Someone who already has a large amount in cash faces a tradeoff between immediate market exposure and gradual entry. Because markets have historically risen over long periods, delaying also has an opportunity cost.
Risk tolerance and time horizon matter.
The asset choice still dominates
Regularly buying a concentrated or unsuitable investment does not fix its risks. Diversification, fees, and the goal for the money remain central.
The schedule supports the plan. It is not the plan itself.
