Dollar-cost averaging is a contribution schedule

Investing the same amount at regular intervals can reduce the pressure of choosing one perfect entry point.

It does not turn a weak business into a strong one

If a company’s competitive position deteriorates, repeated purchases simply increase exposure to the same problem.

The investment thesis still needs review

Material changes in the industry, finances, governance, or valuation should not be ignored just because contributions are automated.

Separate the method from the asset

Dollar-cost averaging answers how to invest over time. Choosing what to own is a separate decision.

How to verify information

Start with company filings, exchange/regulatory sources, and primary disclosures before relying on media summaries or market commentary. When sources conflict, prioritize formal filings and primary sources.
