I have a lot of similar experience having worked in different divisions of PwC and EY.
I'll warn you now that those firms are full of politics. The work itself wasnt rewarding for me at all, everytime I wanted to do test for certain things they told me all I have to do is the same thing as last year (even though more than often I could prove last years testing was stupid and wrong).
I have also gone for CFA level 1, it is very interesting...but it will only help you if you want to get a job in that industry. Personally I like working for myself.
I know that a lot of people here will tell you to go after the money (whichever route they argue). The truth from my experience is firstly the money is not important, you will make money whichever route you go. In all honesty though trading will provide you with the most, having been through several careers myself it is the only career I have found where one can turn 70k into 700k in a year.
What is important is you need to ask yourself what is it you enjoy and what is it you enjoy about the markets?
If you like financial analysis, go for the CFA route, if you enjoy dealing with businesses and day to day operations, setting up company reports, go CA.
Personally I enjoy learning about investments and at the same time I do technical and mathematical analysis on the JSE to find statistical edges..and then I trade that.
I like learning some of the more intricitate structures like Zero-cost collars and hedging - but you dont need any of this to do well (the one SA trader made R9mil with R 800k in 2 years looking at a blue and a red line).
You dont need a qualification for the markets (like CMT) most of the stuff youll learn you can find for free on the internet or just ask.
Sorry for the long message, hope it helps.
