If you are predisposed to be patient, disciplined and psychologically appreciate the idea of buying bargains, then you're likely to be good at it. If you have a need for action, if you want to be involved in the new and exciting technological breakthroughs of our time, that's great, but you're not a value investor, and you shouldn't be one.

Value investing is simple to understand but difficult to implement. Value investors are not supersophisticated analytical wizards who create and apply intricate computer models to find attractive opportunities or assess underlying value. The hard part is discipline, patience, and judgment. Investors need discipline to avoid the many unattractive pitches that are thrown, patience to wait for the right pitch, and judgment to know when it is time to swing.

It sounds kind of crazy, but in times of turmoil in the market, I've felt a sort of serenity in knowing that I've checked and re-checked my work, one plus one still equals two regardless of where a stock trades right after I buy it.

Investing is the intersection of economics and psychology.

While some might mistakenly consider value investing a mechanical tool for identifying bargains, it is actually a comprehensive investment philosophy that emphasizes the need to perform in-depth fundamental analysis, pursue long-term investment results, limit risk, and resist crowd psychology.

Value investing is risk aversion.

Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.

Once you adopt a value-investment strategy, any other investment behavior starts to seem like gambling.

The average person can’t really trust anybody. They can’t trust a broker, because the broker is interested in churning commissions. They can’t trust a mutual fund, because the mutual fund is interested in gathering a lot of assets and keeping them. And now it’s even worse because even the most sophisticated people have no idea what’s going on.

To achieve long-term success over many financial market and economic cycles, observing a few rules is not enough. Too many things change too quickly in the investment world for that approach to succeed. It is necessary instead to understand the rationale behind the rules in order to appreciate why they work when they do and don't when they don't.

Because investors are not usually penalized for adhering to conventional practices, doing so is the less professionally risky strategy, even though it virtually guarantees against superior performance.

Value in relation to price, not price alone, must determine your investment decisions. If you look to Mr Market as a creator of investment opportunities (where price departs from underlying value), you have the makings of a value investor. If you insist on looking to Mr Market for investment guidance however, you are probably best advised to hire someone else to manage your money.

The trick of successful investors is to sell when they want to, not when they have to.

Value investing is at its core the marriage of a contrarian streak and a calculator.

Investors should always keep in mind that the most important metric is not the returns achieved but the returns weighed against the risks incurred. Ultimately, nothing should be more important to investors than the ability to sleep soundly at night.
