John Maynard Keynes quotes about
mistake thinking risk
It is a mistake to think that one limits one’s risk by spreading too much between enterprises about which one knows little and has no reason for special confidence.
strong roots differences
A conventional valuation which is established as the outcome of the mass psychology of a large number of ignorant individuals is liable to change violently as the result of a sudden fluctuation of opinion due to factors which do not really make much difference to the prospective yield; since there will be no strong roots of conviction to hold it steady.
optimistic acting pessimistic
If we consistently act on the optimistic hypothesis, this hypothesis will tend to be realised; whilst by acting on the pessimistic hypothesis we can keep ourselves for ever in the pit of want.
principles unattractive merit
The central principle of investment is to go contrary to the general opinion, on the grounds that if everyone agreed about its merits, the investment is inevitably too dear and therefore unattractive.
mistake believe thinking
As time goes on, I get more and more convinced that the right method in investment is to put fairly large sums into enterprises which one thinks one knows something about and in the management of which one thoroughly believes. It is a mistake to think that one limits one's risk by spreading too much between enterprises about which one knows little and has no reason for special confidence. . . . One's knowledge and experience are definitely limited and there are seldom more than two or three enterprises at any given time in which I personally feel myself entitled to put full confidence.
ideas encroachment interest
I am sure that the power of vested interests is vastly exaggerated compared with the gradual encroachment of ideas.
spiritual civilization intellectual
They offer me neither food nor drink - intellectual nor spiritual consolation... [Conservatism] leads nowhere; it satisfies no ideal; it conforms to no intellectual standard, it is not safe, or calculated to preserve from the spoilers that degree of civilization which we have already attained.
suffering forget share
I was suffering from my chronic delusion that one good share is safer than ten bad ones, and I am always forgetting that hardly anyone else shares this particular delusion.
safety needs resources
An investor who proposes to ignore near-term market fluctuations needs greater resources for safety and must not operate on so large a scale, if at all, with borrowed money.
numbers safety different
To suppose that safety-first consists in having a small gamble in a large number of different companies where I have no information to reach a good judgment, as compared with a substantial stake in a company where one's information is adequate, strikes me as a travesty of investment policy.
loss long investing
It is the duty of the long-term investor to endure great losses with equanimity.
expectations matter would-be
It would be foolish, in forming our expectations, to attach great weight to matters which are very uncertain.
humble heaven vastness
I don't feel the least humble before the vastness of the heavens.
eye average essence
It is the long-term investor...who will in practice come in for the most criticism... For it is the essence of his behavior that he should be eccentric, unconventional, and rash in the eyes of average opinion
