Investor Behavior Quotes

Ridiculous as our market volatility might seem to an intelligent Martian, it is our reality and everyone loves to trot out the 'quote' attributed to Keynes (but never documented): 'The market can stay irrational longer than the investor can stay solvent.' For us agents, he might better have said 'The market can stay irrational longer than the client can stay patient.'

Far more money has been lost by investors preparing for corrections, or trying to anticipate corrections, than has been lost in corrections themselves.

The most important organ in the body as far as the stock market is concerned is the guts, not the head. Anyone can acquire the know-how for analyzing stocks.

I believe, in the stock market - that's one of my fields - that most people are irrational. And to be irrational, you can be irrational in so many different ways that, practically, the result is indeterminate.

As a bull market turns into a bear market, the new pros turn into optimists, hoping and praying the bear market will become a bull and save them. But as the market remains bearish, the optimists become pessimists, quit the profession, and return to their day jobs. This is when the real professional investors re-enter the market.

One thing on psychology, which we've always known, is that every investor says they're long-term - and they are until the market takes a hit.

It's human nature: for most investors, the pain of stocks going down is more tangible than the joy of when they go up. The common impulse is to do something - anything - to minimise the pain.

It's the investor who is risky, not the investment.

One of the funny things about the stock market is that every time one person buys, another sells, and both think they are astute.

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.

Usually, you measure appetite of investors by their ability or willingness to take a bit of leverage on their positions.

Often, investors will discover a manager after he's had a terrific run, usually when he lands on a magazine cover somewhere. Invariably, funds swell up with new investor money just before they revert to their long-term averages.

I think those who invest in mutual funds want someone else to do the thinking for them. But the fact that they can move the money around the family of mutual funds just through a phone call lets them feel that they can play tycoons.

When I stand on my special-issue "Intelligent Investor" ladder and peer out over the frenzied crowd, I see very few others doing the same. Many stocks remain overvalued, and speculative excess - both on the upside and on the downside - is embedded in the frenzy around stocks of all stripes. And yes, I am talking about March 2001, not March 2000.

The market is a pendulum that forever swings between unsustainable optimism (which makes stocks too expensive) and unjustified pessimism (which makes them too cheap). The intelligent investor is a realist who sells to optimists and buys from pessimists.

Be fearful when the markets get greedy, be greedy when the markets get fearful.

Many investors make the mistake of buying high and selling low while the exact opposite is the right strategy.

The biggest mistake investors make is to believe that what happened in the recent past is likely to persist. They assume that something that was a good investment in the recent past is still a good investment. Typically, high past returns simply imply that an asset has become more expensive and is a poorer, not better, investment.

Volatility may be rising simply because investors must digest more information every day.

The most realistic distinction between the investor and the speculator is found in their attitude toward stock-market movements. The speculator's primary interest lies in anticipating and profiting from market fluctuations. The investor's primary interest lies in acquiring and holding suitable securities at suitable prices. Market movements are important to him in a practical sense, because they alternately create low price levels at which he would be wise to buy and high price levels at which he certainly should refrain from buying and probably would be wise to sell.

The adaptive markets hypothesis says that all economic institutions, like our own species, develop and change over time, depending on the population of investors that are engaged with them.

The investment business has taught me – increasingly as the years have passed – that people, especially investors (and, I believe, Americans), prefer good news and wishful thinking to bad news; and that there are always vested interests to offer facile, optimistic alternatives to the bad news.

Volatility is a symptom that people have no idea of the underlying value-that they have stopped playing the asset game. They're not buying because it's a company with certain attributes. They're buying because the price is rising. People are playing games not related to any concept at all of what the long-term value of the enterprise is. And they know it.

But whatever the consensus on the EMH, I know of no serious academic, professional money manager, trained security analyst, or intelligent individual investor who would disagree with the thrust of EMH: The stock market itself is a demanding taskmaster. It sets a high hurdle that few investors can leap.
