absolutely, you have the charter and I m just a level II candidate. But I have aways seen Joe Doe, CFA and never
Joe Doe CFA. Maybe some other other charter holder would know.
The Standards handbook does not discuss the use of a comma or not and none of the examples show it without a comma right or wrong. Only way to know for sure is to call or email CFAI.
Seems to me like the comma issue is more of a formatting thing than it is standards. It looks funny because it’s improper to omit the comma and that’s all there is to it, but then again I’ve only looked over the Schweser notes so maybe its a bigger deal than I realize.
