If you do experience mood swings around losing trades, it’s probably because you are evaluating yourself by the criterion of being right–not by the criterion of trading well. It isn’t the losing trade making you feel bad; it’s the perfectionistic expectation that you should always be right. By embracing uncertainty and staying open to learning from it, the threat of losing can turn into the opportunity of rethinking market assumptions.
His key warning:
In my judgment the authorities have a three months’ window during which they could still correct their mistakes and reverse the current trends. By the authorities I mean mainly the German government and the Bundesbank because in a crisis the creditors are in the driver’s seat and nothing can be done without German support.
He ends with a plea:
We need to do whatever we can to convince Germany to show leadership and preserve the European Union as the fantastic object that it used to be. The future of Europe depends on it.

Ever since the Crash of 2008 there has been a widespread recognition, both among economists and the general public, that economic theory has failed. But there is no consensus on the causes and the extent of that failure.
I believe that the failure is more profound than generally recognized. It goes back to the foundations of economic theory. Economics tried to model itself on Newtonian physics. It sought to establish universally and timelessly valid laws governing reality. But economics is a social science and there is a fundamental difference between the natural and social sciences. Social phenomena have thinking participants who base their decisions on imperfect knowledge. That is what economic theory has tried to ignore.
Scientific method needs an independent criterion, by which the truth or validity of its theories can be judged. Natural phenomena constitute such a criterion; social phenomena do not. That is because natural phenomena consist of facts that unfold independently of any statements that relate to them. The facts then serve as objective evidence by which the validity of scientific theories can be judged. That has enabled natural science to produce amazing results.
Social events, by contrast, have thinking participants who have a will of their own. They are not detached observers but engaged decision makers whose decisions greatly influence the course of events. Therefore the events do not constitute an independent criterion by which participants can decide whether their views are valid. In the absence of an independent criterion people have to base their decisions not on knowledge but on an inherently biased and to greater or lesser extent distorted interpretation of reality. Their lack of perfect knowledge or fallibility introduces an element of indeterminacy into the course of events that is absent when the events relate to the behavior of inanimate objects. The resulting uncertainty hinders the social sciences in producing laws similar to Newton’s physics. (more…)
“Four years ago, I told you that we needed to add one or more younger investment managers to carry on when Charlie, Lou and I weren’t around. At that time we had multiple outstanding candidates immediately available for my CEO job (as we do now), but we did not have backup in the investment area.
It’s easy to identify many investment managers with great recent records. But past results, though important, do not suffice when prospective performance is being judged. How the record has been achieved is crucial, as is the manager’s understanding of – and sensitivity to – risk (which in no way should be measured by beta, the choice of too many academics). In respect to the risk criterion, we were looking for someone with a hard-to-evaluate skill: the ability to anticipate the effects of economic scenarios not previously observed. Finally, we wanted someone who would regard working for Berkshire as far more than a job.
When Charlie and I met Todd Combs, we knew he fit our requirements. Todd, as was the case with Lou, will be paid a salary plus a contingent payment based on his performance relative to the S&P. We have arrangements in place for deferrals and carryforwards that will prevent see-saw performance being met by undeserved payments. The hedge-fund world has witnessed some terrible behavior by general partners who have received huge payouts on the upside and who then, when bad results occurred, have walked away rich, with their limited partners losing back their earlier gains. Sometimes these same general partners thereafter quickly started another fund so that they could immediately participate in future profits without having to overcome their past losses. Investors who put money with such managers should be labeled patsies, not partners. (more…)
