A simple analogy to illustrate the short comings of the CFA program.

Throughout the 3 levels, we are taught about efficient frontier and methods to quantify risk and return (CAPM), and techniques to maximize your return (sliding up and down the CML for example) based on it. AT the end of the day, we are all experts in answering investment questions, GIVEN the frontier.

But nowhere does it tell you how to actually derive the frontier (well, to be fair, there are qualitative mentions of various techniques in L3, if only briefly). Now imagine you are a PM, do you reckon the frontier will be presented to you at work? Even if it is, are you sure it is even efficient in the most basic sense? Even so, are you able to incorporate some personal insights that you have into the frontier? Not from just CFA at least.

And quite frankly, what do you reckon is your sustainable competitive advantage over a fellow PM? Yes, it is the ability to quickly incorporate new information into the models you developed, one of which must be the efficient frontier.

The point I'm trying to make this is: CFA tells you the important things in PM and equity management, but it doesn't tell you how to go about deriving it quantitatively. And without that frontier, it doesn't matter how well you know your CFA stuff because you have nothing to apply to.

In my opinion, the most valuable thing about CFA, which ironical is also what people hate most, is FSA. It forces one to read financial statements and make sense of it.

As for the practical aspects of actually managing a portfolio, or the quantitative analysis, well, let's just say it is like fastfood - all grease, but where is the meat?

Derivation of the frontier is just one simple example, and there are many more. For example, the entire part on derivatives is almost akin to high school material in today's finance. The treatment on time series, or the entire quant aspect of CFA, is at best cursory. The list goes on.

Well, you might argue: Do we need to know some much math/stats. Let's just say that knowledge of these analytical tools gives you the competitive advantage. Sure, one can survive on just the basics from CFA, but at some point, you'll find the lack of tools wanting.
 
I know you have posted this question before...but as I stated before the reason they only show a 2 or 3 asset portfolio for the Efficient frontier is the amount of calculations that must be done wi th the correlation and covariance matrixes, etc. In today's world you have software that you will need to supply the inputs and it will give you the efficient frontier, you can even create a worksheet in Excel to do this for you, NOT EASY though. The important thing is the quality of the inputs you put into the models, because as the old saying goes, Garbage In/Garbage Out. I rememeber in my undergrad finance years a Portfolio manager talking with us from Legg Mason and he showed us the efficient frontier being utilized in the real world and guess what, he had software that created it for him, he just need to provide the correct variables.

Does that help?

you forgot to attribute this to propanol - I think above are his words. As a budding analyst get in habit of attributing source ;-)
 
I knew that I read this before and responded to this before :). You will now fail your CFA exams due to Plagarism. The CFA Institute has been notified of your current IP Address. :) Ok back to work...

yeah, to achieve what the original poster wants we'd all need to bring excel to the exam. that would be too time consuming to have in the exam, it would be impratical because we'd waste alot of time on one section without developing the broader understanding necessary of a competent analysis/PM. its best they stay with the original format because even quantitative geniouses like stephen hawking use computers and software to derive those types of answers. All we need to know as PMs is the conceptual framework behind it, then we can get some compsci geek to program it for us.

@#$%&, i gotta go to bed, gots lots of number crunchin to do tommorrow heheh
