Which factor forms the basis of an appropriateness test?

The appropriateness test, as outlined in financial regulations like MiFID II, evaluates whether a client has the necessary knowledge and experience to understand the risks of a financial product or service. This is particularly applicable when a client is investing in complex or non-advised products.

Age (A): While relevant to certain suitability tests, age is not a determinant of appropriateness.

Qualifications (C): Although qualifications may indicate some level of understanding, they are not a core requirement for the test.

Wealth (D): Wealth does not equate to investment knowledge or experience.
