Arrive Already Knowing

There are two kinds of money advice, and both fail you in the same place. At the bottom, when it counts.

The first sells speed. Tickers, leverage, the rush of being right. It fails you in the panic, because it taught you to need the thrill, and one day the thrill turns on you. The second is wiser, and it still fails most people. Buy the whole market, close your eyes, hold through anything. That is an easy sentence to write. It is a nearly impossible one to obey when your savings are down a third and the news agrees with your fear.

17 Years is for the space between. For the person who can do the arithmetic and still smell the nonsense, who wants neither the casino nor the lullaby.

The arithmetic

Start here, because this one number decides more than everything else put together. The share of your pay you keep, not the returns you earn, sets the date you go free.

Take home a paycheck and live on half of it. The other half is a year you will not have to work, set aside whole. You set aside another for every year you keep working. Leave that money alone. Let ordinary growth work it the way weather works a field, slow and without your hand. In about seventeen years, what you have saved throws off enough to cover your life without your labor.

That crossover is a real number you can write down today. It is roughly twenty-five times what you spend in a year. The fund you pick barely moves it. The gap between what you earn and what you spend moves it, and that gap is the one lever the market cannot reach.

The chart they sell you

There is a chart every index seller loves. One dollar put into US stocks in 1871 grows to about thirty-five thousand today, after inflation, with every dividend reinvested. Every catastrophe on it, the Panic of 1907, the Depression, Black Monday, shrinks to a dent. The pitch writes itself. Hold long enough and nothing can touch you.

Now look at the flat stretches on that same line, the years the market spent underwater, grinding back to a peak it had already hit. How long they lasted depends on what you count, so count it both ways and be honest each time.

On the screen, in the plain price the chart plots, the market did not reclaim its 1929 high until 1954. Twenty-five years. Strip out dividends and adjust for inflation, the way many "real return" charts do, and it is worse, not better. The 1929 peak took twenty-nine years to come back in real terms, the 1968 peak twenty-three, the peak before the First World War twenty-two.

Now be as kind to the market as the arithmetic allows. Reinvest every dividend and adjust for inflation, which is the most any investor could have done. The droughts shrink. They do not close. Two thousand to 2013, thirteen years. 1973 to 1985, twelve. The 1929 crash clawed its losses back by the end of 1936, lost them again within a year, and did not durably return until the spring of 1945. Seven years, a false dawn, then eight more.

Pick any measure you like. The kindest one still buries you for a decade at a stretch, and it did so twice in the last fifty years.

A working life gives you about forty investing years. That chart eats them a decade at a bite. The market had a century and a half to be right. You get the forty, and you do not get to choose which forty. Retire your savings into 1968 or 2000 and "hold through anything" was a promise made to someone who lives forever, sold to someone who does not.

Be fair to the chart, because it flatters us. That line is US large-cap stocks, the single greatest run in the history of markets, survivorship bias pointing your way. The underwater stretches are the good case. They are what the winner looked like.

What we add

What we add to the arithmetic is not a way to beat the market. It is a way to survive your own forty years of it.

You stay invested and you keep buying. What changes is how much risk each dollar carries, set by reading the weather instead of forecasting it. We keep one instrument, the Climate Reading. It asks two plain questions. Are stocks cheap or dear against the yield on safe government bonds, and is the trend holding or breaking. When the weather is fair you hold more. When it turns you hold less. The reading sets the amount, so the decision is already made on the morning the headlines turn frightening and you are most tempted to make it badly.

This will disappoint anyone hunting an edge. We do not have one, and we will not sell you one. In the long calm bull markets that make everyone feel like a genius, this trails the person who held everything and felt nothing. We say so out loud, because a method that hides its weak season is only a story told in a quieter voice.

I will not tell you the instrument would have skipped those underwater decades. A slow rule gets whipsawed in some of them, and anyone who promises you a clean escape is selling the same fantasy in a costume. The honest claim is smaller, and it is still the whole game. When the descent comes, and across forty years it comes, you go down carrying less and you keep buying the whole way. The hole is shallower. A hole you can climb out of is a different thing entirely from one you sell at the bottom of.

The years

The market, as an old book put it, is an expensive place to find out who you are. Most people pay that tuition in a single afternoon of fear, sell near the bottom, and never earn the money back. That afternoon is what separates the return a fund earned from the return its owner took home. A rule set in the calm is how you skip the lesson. You decide now, while nothing is happening, and you let the rule hold the line later, when the story in your head turns loud.

There is not much to the work. A savings rate you can live with. An instrument you can read in a minute. And under both, the harder thing: a willingness to be unexciting for a long time, on purpose, while the years do their slow arithmetic.

Seventeen of them, give or take. You can spend those years braced against a market that was never out to get you, awake at three in the morning doing math you cannot win. Or you can spend them asleep. We would rather you slept. Position, and let the weather be weather.

You can arrive already knowing.
