To value investors the concept of indexing is at best silly and at worst quite hazardous. Warren Buffett has observed that "in any sort of a contest - financial, mental or physical - it's an enormous advantage to have opponents who have been taught that it's useless to even try." I believe that over time value investors will outperform the market and that choosing to match it is both lazy and shortsighted.

Investing is the intersection of economics and psychology. The analysis is actually the easy part. The economics, the valuation of the business isn't that hard. The psychology - how much do you buy, do you buy it at this price, do you wait for a lower price, what do you do when it looks like the world might end - those things are harder. Knowing whether you stand there, buy more, or whether something has legitimately gone wrong and you need to sell, those are harder things. That you learn with experience, by having the right psychological makeup.

People should be highly sceptical of anyone's including their own, ability to predict the future, and instead pursue strategies that can survive whatever may occur.

We suppose that could be considered a hedged position for the awards committee, one that would never occur in the hard sciences such as physics and chemistry, where a prize shared among three with divergent views would be an embarrassing mistake or a bad joke. While a Nobel Prize might well be the culmination of a life’s work, shouldn’t the work accurately describe the real world?

Right at the core, the mainstream has it backwards. Warren Buffett often quips that the first rule of investing is to not lose money, and the second rule is to not forget the first rule. Yet few investors approach the world with such a strict standard of risk avoidance.

Value investors will not invest in businesses that they cannot readily understand or ones they find excessively risky. Hence few value investors will own the shares of technology companies. Many also shun commercial banks, which they consider to have unanalyzable assets, as well as property and casualty insurance companies, which have both unanalyzable assets and liabilities.

I think markets will never be efficient because of human nature.
