In the stock market, the most important organ is the stomach. It’s not the brain…

Do you really have faith that 10 years, 20 years, 30 years from now common stocks are the place to be. If you believe in that, you should have some money in equity funds. It’s a question of what’s your tolerance for pain. There will still be declines. It might be tomorrow. It might be a year from now. Who knows when it’s going to happen? The question is: Are you ready — do you have the stomach for this?

Most people do really well because they just hang in there. — Peter Lynch (source)

The best investors are masters of subtraction. They played the game long enough to simplify their investment philosophy down to a few key principles. And it did wonders for their portfolio.

The goal of investing should be to eliminate things that have a high probability of producing losses. These are things that you know won’t work. Things you don’t understand well. Things that are too complex. Things that are distractions and noise. Things that lead to mistakes. Things that are irrelevant, unimportant, and unnecessary to your process. Anything that doesn’t fit what you’re trying to do should be cut out.

The problem for most investors is we know none of this when we start out. Each one of us must go through the slow and sometimes painful experience of figuring it out.

Yet the idea of improving things by subtraction flies in the face of human nature. Our typical response to problem-solving is to make things more complex. Addition is our default.

In a series of studies by Adams, Klotz, et al, the overwhelming result was to add rather than subtract features to solve a problem. Continue Reading…

Quote for the Week

Every sale raises a series of questions, often surrounding relative values and opportunity costs. What will you do with the proceeds? Do you have something in mind that you think might produce a superior return? What might you miss by switching to the new investment? And what will you give up if you decide not to switch and continue to hold the asset in your portfolio? Or perhaps you decide to sell and don’t plan to reinvest the proceeds. In that case, what’s the likelihood that holding the proceeds in cash will make you better off than you would have been if you had held on to the thing you sold? Selling an asset is a decision that absolutely must not be considered in isolation. — Howard Marks (source)

There are economic agents who make large and predictable mistakes. For example, individuals who invest on their own characteristically make large and expensive mistakes. If we analyse individual transaction in which an individual investor bought a stock and sold another in a single day, it is safe to assume this transaction is not based on liquidity. What determines the individual’s behaviour is the belief that one stock will outperform the other. Now with modern technology we can easily analyse the outcomes of this single-day transaction a year later, and the results are quite astonishing. On average, the stock that a person sold did better than the stock they bought, but it’s not only that it did better — it did better by a large amount. The average is 3.4 percent. These results have been replicated many times over.

This phenomenon leads to a very simple notion: there is an average cost of having an idea for an investor, and the average cost is about 3 percent, which is quite a lot. So, having ideas cost people money, and people have lots of ideas. Individual investors tend to churn their accounts, they tend to trade too much, and that they trade too much seems to be due over-confidence. They believe they know something that they do not know and this is one essential characteristic of human beings, which makes them different from rational beings. — Daniel Kahneman (source)
