Volatility from a 5 year perspective: Welcome to the 1825 days year

Once upon a time, at the birth of our solar system, the time for the earth to spin around the sun became the 365 1/4 days we are used to.

It was a God given, a necessity, perhaps, and of course entirely out of human control.

Those 365 days has some impacts on our life, and certainly our evolution. For the two of us, the arctic summer and winter are a stark reminder of the solar year, on other places closer to the equator the climate will be more stable year round. 

The Arctic Sun

In the heated, air-conditioned, civilized life of today, the impact of earth's rotation on everyday life is smaller. The time it takes for earth to orbit the sun would seem even more arbitrary if one lived outside our frame of reference, let's say on one of the moons of Jupiter. 

From a more elevated perspective, an earth year is a seemingly randomly set constant.

Yet, we tend to give this period an out-of-proportion importance. We count our age in it, we celebrate the summer and winter solstice and equinoxes with rites and feasts. 

In finance the year has significance as well; as if the returns of our investments where a crop to be harvested every year. The year is the basis for what we understand with returns; if we see the number 7% it's assumed that it's the annual return that is meant. 

What is the impact of this metaphor on our thinking about investments? Investments that might not really care about the arctic sun, the moons of Jupiter or the passing of midsummer? 

What if we measured returns in another constant? 

Let's say that we just as arbitrarily instead measured a new unit that we set at 43 800 earth hours, or 1825 earth days, corresponding to 5 earth years. 

A unit, as if earth was spinning five years slower than we are used to. Or as if one only can be bothered to have a look at the planet every five year and wouldn't notice that it's actually spinning faster. Or as if we saw that grand red dot in the clouds of the gas giant Jupiter from our moon every five years, and measured the passing of time in red-dot-revolutions and not earth years.

What would we think of our investments then? How would volatility look with our new, more relaxed, slower 1825 days year's perspective? What decisions would we make?

Let's plot our pathfinder portfolio's return excluding inflation in a logarithmic diagram, with our normal earth years and our new, 1825-days-years. 

A thin red thread that always strives upwards

And voilà. An almost straight, red line that always marshes on upwards and never ever turns the other way. It's the same return, just with a lower resolution.

Our way of looking at things are bound by conventions that might be out of place. This hints on what volatility looks like for the Gods. 

And perhaps, it could for us too.
