I don't entirely reject the idea of efficient markets. It needs updating.
The efficient market theory is one of the better models in the sense that it can be taken as true for every purpose I can think of. For investment purposes, there are very few investors that shouldn't behave as if markets are totally efficient.
Reject labels. Reject identities. Reject conformity. Reject convention. Reject definitions. Reject names.
What I love is this idea of a wardrobe, the idea that we're establishing certain signatures and updating them, that a change in colour or fabric is enough.
Capitalism has taught us that markets are always more efficient than hierarchical managerial coordination. But in a situation where those three conditions aren't met, I can't outsource or partner with you because markets don't function in the absence of sufficient information.
In certain circumstances, financial markets can affect the so-called fundamentals which they are supposed to reflect. When that happens, markets enter into a state of dynamic disequilibrium and behave quite differently from what would be considered normal by the theory of efficient markets. Such boom/bust sequences do not arise very often, but when they do, they can be very disruptive, exactly because they affect the fundamentals of the economy.
I think there's a lot of merit in an international economy and global markets, but they're not sufficient because markets don't look after social needs.
Markets do not run better when manufacturing shifts to China largely because of the actions of its government. Nor do they become more efficient when Chinese companies are given special privileges in global markets, while American companies must struggle to compete with unfairly traded goods.
The markets are efficient over time.
Financial markets need to become less, not more, efficient.
The thing about markets, and I think the thing people don't understand about that, is markets are not kind, but they're very efficient. So when the marketplace determines an inefficiency in the system, it corrects that, and a market system that's left alone will reward good behavior and punish bad behavior.
More and more investors may be coming into markets everywhere but that doesn't mean that the markets are really getting more and more efficient, even in the United States. It does mean that there is more access for savvy investors who watch the money flows.
I think markets will never be efficient because of human nature.
Teach [our girls] that there is a race with special needs which they and only they can help; that the world needs and is already asking for their trained, efficient forces.
I have noticed that everyone who has ever tried to tell me that markets are efficient is poor.
You know what term you don't hear anymore? Arbitrage. The markets have gotten too efficient.
If we have an element of Americans here that reject western civilization, and that's a big element, that reject western civilization, then what have we? This is an effort on the left I think to break down the American civilization and the American culture and turn it into something entirely different.
