Dollar-cost averaging
In plain English
Dollar-cost averaging means investing a fixed amount on a schedule (like every paycheck), no matter what the price did that week. It reduces the stress of “perfect timing.”
Everyday analogy: Filling your gas tank a little every week instead of guessing the cheapest day of the year.

Why it matters
DCA is a behavior system for staying invested when timing anxiety would keep you in cash.
A bit more detail (optional)
What it does
You buy on a calendar. Lower prices buy more shares; higher prices buy fewer - automatically.
What it doesn’t guarantee
DCA does not always beat lump sum in rising markets. Its main gift is helping you stay invested when timing anxiety would keep you in cash.
Simple examples
Paycheck investing
Investing $500 each month into a broad fund turns salary into a process instead of a prediction contest.
Paycheck process
Investing a fixed amount each payday into a broad ETF removes the need to guess next week’s open.
Easy mistakes to avoid
- Stopping DCA after a drop - the moment it helps most
- DCA into a single speculative name as if it were an index
- Using DCA as an excuse never to review a broken thesis
Remember: DCA is a behavior tool - keep the schedule when fear is loudest.
