Which practice ensures that market data is reliable when Forbes publishes it?

• A. Always omit the data source to keep the article clean.
• B. Use unverified numbers if faster.
• C. Cite the data source, display currency and units, and verify timeliness.
• D. Rely on memory for market values.

Answer: (C)

Reliable market data comes from transparency about where the numbers come from and when they were collected. The best practice is to cite the data source, display currency and units, and verify timeliness.

Citing the data source lets readers verify origin and assess credibility; it provides a trail they can follow if they want more detail or to check reliability. Displaying currency and units removes ambiguity—readers should know exactly what is being reported (for example, price per share versus total market value, and which currency is used). Verifying timeliness ensures the information reflects the current situation rather than something that’s already outdated in fast-moving markets.

Omitting the data source hides the source of the numbers, making verification impossible. Using unverified numbers risks inaccuracy and misrepresentation, especially if the figures are challenged or outdated. Relying on memory for market values is prone to error and cannot be checked or trusted over time.
