“No statement is more true and better applicable to Wall Street than the famous warning of Santayana: “Those who do not remember the past are condemned to repeat it”.”

Stock speculation is largely a matter of A trying to decide what B, C and D are likely to think-with B, C and D trying to do the same.

The modern world is not geared properly to the storage of goods.

Many progressive economists insist that gold is now in essentially the same position as silver and that the arguments the simon-pure gold advocates use against the white metal can be directed with equal effect against their own fetish.

The chief losses to investors come from the purchase of low-quality securities at times of favorable business conditions.

Speculative stock movements are carried too far in both directions, frequently in the general market and at all times in at least some of the individual issues.

The true investor… will do better if he forgets about the stock market and pays attention to his dividend returns and to the operation results of his companies.

The utility, or intrinsic value of gold as a commodity is now considerably less than in the past; its monetary status has become extraordinarily ambiguous; and its future is highly uncertain.

Most of the time common stocks are subject to irrational and excessive price fluctuations in both directions as the consequence of the ingrained tendency of most people to speculate or gamble… to give way to hope, fear and greed.

It is worth pointing out that assuredly not more than one person out of a hundred who stayed in the market after after 1925 emerged from it with a net profit and that the speculative losses taken were appalling.

Rather should we say that the market is a voting machine, whereon countless individuals register choices which are the product partly of reason and partly of emotion.

Price statistics show clearly that instability in raw-material prices is a prime cause of instability of other prices.

No matter how careful you are, the one risk no investor can ever eliminate is the risk of being wrong. Only by insisting on what Graham called the “margin of safety” – never overpaying, no matter how exciting an investment seems to be – can you minimize your odds of error.

Though business conditions may change, corporations and securities may change, and financial institutions and regulations may change, human nature remains the same.

Buy when most people, including experts, are pessimistic, and sell when they are actively optimistic.

Investing isn’t about beating others at their game. It’s about controlling yourself at your own game.

By refusing to pay too much for an investment, you minimize the chances that your wealth will ever disappear or suddenly be destroyed.

There is a close logical connection between the concept of a safety margin and the principle of diversification.

You must never delude yourself into thinking that you’re investing when you’re speculating.

As in roulette, same is true of the stock trader, who will find that the expense of trading weights the dice heavily against him.

Thousands of people have tried, and the evidence is clear: The more you trade, the less you keep.

The best approach here, if at all possible, is to use supervisory and regulatory methods to restrain undue risk-taking and to make sure the system is resilient in case an asset-price bubble bursts in the future.

All economic movements, by their very nature, are motivated by crowd psychology.

We have not known a single person who has consistently or lastingly make money by thus “following the market”. We do not hesitate to declare this approach is as fallacious as it is popular.

An intelligent investor gets satisfaction from the thought that his operations are exactly opposite to those of the crowd.
