Performance review August 2013 – Comment: “Circle of Competence”


The portfolio lost -0.6% in August, compared with -1.1% in the BM (50% Eurostoxx, 30% Dax, 20% MDAX). YTD the portfolio is up 21.4% against 12.5% for the benchmark.

The major driver was of course the 25% cash allocation in a down month, the single stocks were all within low single digit perfomance in either direction, so nothing special here.

Portfolio transactions

August was a rather active month with 4 relevant transaction:

1. AS Creation was sold out
2. MIKO came in as new “Core Value” investment (half position)
3. A 1% position in Pharmstandard as potential special situation was established
4. In parallel, I am building up a position in a yet undisclosed French company where I did not yet manage to write a post but I include it “anonymously” in the portfolio

Comment: Circle of Competence

For most value investors, Warren Buffet’s concept of “Circle of Competence” is a very important guideline.

Here is a video of the Oracle himself explaining the concept.

Most famously, he avoided the Dotcom bubble by staying within his circle of competence and not investing in tech companies. Many people therefore take this advice as granted and tend to stay in an area which they know best, like German small caps etc.

However I have a serious problem with this concept or at least with the interpretation of it.

First of all, in reality, each of us is born without any circle of competence with regard to investments. So whatever you consider as your CoC now, has been outside your initial CoC. So at one point in time one had to step out this “zero CoC” to build up any kind of competence.

It is also funny to listen to Warren Buffet explaining this concept. His CoC is HUGE. Clearly, his most well-known investments are Coca Cola, Gilette etc. But if your really follow his investment career, you can clearly see that he continuously expanded his circle of competence..

I mean he started with delivering newspapers and putting pinball machines into Barber shops, but then over his career he almost did everything. Starting with buying department stores, newspapers, he invested in commodities (Silver) Chinese companies, Israeli companies, sold CDS, S&P 500 puts, bought reinsurance companies, provided LBO financing etc. etc.

Expanding one’s CoC however only works if you step outside your CoC a least a little bit at one point in time. Clearly, jumping blindly without any knowledge for instance into US listed Chinese stocks normally does not end well.

I think the best way to expand one’s circle of competence is along the following dimensions:

a) Geographically
So if one has a lot of knowledge in one sector like for instance car manufacturers, it is not that difficult to look at those companies in other countries in order to gain experience. Due to the fact that many companies today are very international, this kind of knowledge in my opinion is extremely important anyway. Just looking at the 3 German car manufacturers for instance is a quite useless task. Usually it is easier to look at “familiar” countries first before going to more exotic places. In that way it is easier to learn about specific issues in other countries if you know the sector well.

b) Sector wise
Similar to geographically, it is also relatively easy to move from a sector one knows well to a sector which is in some way connected. So if you are strong in chemicals, to their direct suppliers (Oil companies) or customers should be easier if not necessary. If you know a lot about consumer staples, retailers would be logical next step etc. etc. For me for instance, it was much easier to understand IGE & XAO, the Electro Cad software company after I had analysed what their client G. Perrier is actually doing

c) Along the capital structure
A more unusual way to expand one’s circle of competence is along the capital structure of a company. Usually many people buy stocks and then maybe some bonds. However if you want to more systematically improve your knowledge, start with a company with a more complicated capital structure, including, bonds, loans, Hybrid debt, convertibles and work your way thorough. You will be rewarded with a much better understanding how the financial side of a company works and you might dicover some interesting opportunities along the way.

There are clealry many ways to expand one’s circle of competence, but the three mentioned have worked quite well for me. I think it is important to move in relatively small steps and be patient. Whenever you step out, you will most likely experience a set back, but one should consider this as an investment.

So to sum it up: Don’t let you fool you by Uncle Warren. If he would have stayed with delivering newspapers and putting pinball machines into Barber shops, he most likely would not be one of the richest people of the world. Only if you expand your circle of competence continuously, you will reap the reward over time. However make sure not to jump too far…..


  • If some one wishes expert view concerning blogging after that i
    recommend him/her to go to see this weblog, Keep up the good job.

  • Totally agree with your post. I would add, that some things can’t be mastered (at least not with a sufficient margin of safety) – in that case throw it on the “Too Hard”-pile 😉

  • Congrats to this article. I also cannot hear these Buffet lemmings anymore. The most important thing is to build your own personality which is built on your own experience. No one is able to copy other successful investors. Learning by doing is the right way. And one thing is clear: Our Circle of Competence is very small.

  • Hi MMI,

    Nice post. Another way of looking at CoC is by business model rather than by sector or geography.

    If one can recognize — that is to say, properly evaluate — “scale economies” or “brand” “switching costs”, “regulatory barriers”, etc., then any beneficiary of these is in one’s circle of competence whatever industry/sector/country it is in.

    Buffett is a “scale economies” (Walmart, POSCO, GEICO, WaPo), “regulatory barriers” (Moody’s, BNSF, MidAmerican) and “brand” guy (Dairy Queen, Coke,Heinz, See’s). The sectors, industries, countries may vary but he hasn’t strayed very far or very often from those three bread and butter plays. And when he has — Salomon, commodities, etc — it has rarely turned out well.

    I do agree that capital structure investing is a specialized skill.
