Which business card usage of CFA marks is incorrect?

The use of "C.F.A" in the name of M. S. Chang is incorrect because the designation should not include periods between the letters. The proper presentation of the CFA designation is simply "CFA" without additional punctuation. This maintains clarity and consistency in how the designation is displayed.

In other instances, both "G. J. Anderson, CFA" and "B. K. Baker, Chartered Financial Analyst" are acceptable formats. The first option correctly uses the designation with no periods, while the second correctly spells out "Chartered Financial Analyst," which is also permitted alongside the abbreviation. The variation in these usages reflects appropriate adherence to the guidelines for CFA marks.
