Häromdagen trillade jag över en artikel som räddade min kväll. “The Weird Portfolio
How To Avoid Bubbles, Limit Drawdowns, and Safely Grow Wealth”. Har inte fördjupat mig tillräckligt mycket för att ha en åsikt, men en ganska spännande ansats. Verkar vid första anblick dessutom har bättre siffror än de flesta andra portföljerna (inkl. Golden Butterfly).
Fördelningen
Grundförutsättningarna (som jag tror många av oss kan skriva under på)
It wouldn’t need to predict the future.
It would be low cost.
It would be easy to implement. I don’t want to have to spend hours every week to adjust and hedge positions.
It wouldn’t rely on the genius of a manager whose genius can fade, or whose judgment can be affected by personal trouble.
It would have protection for all of the different kinds of economic environments that the world can throw at it — depressions, recessions, strong dollars, weak dollars, inflation, deflation, prosperity, or the disappointing ending to Game of Thrones.
I wouldn’t have to lose 45%-80% of my money every 15 years.
I wouldn’t have to endure long, lost periods (like 10–25 years) where I didn’t earn any return on my money.
I wouldn’t have to pay someone a lot of money to implement it.
The value of my money wouldn’t fluctuate a lot and stress me out.
Performance
Since 1970, this portfolio has generated an average 7.7% rate of return after inflation. This is almost as high as the US stock market, which has delivered an average real return of 8%.
This result is accomplished with much less severe drawdowns and less volatility than the US stock market.The worst year for this portfolio was 2008, in which it lost 19%. That year, the stock market declined by 37%. Before 2008, the worst year for the portfolio was a loss of only 11%. The stock market declined by 30% during the 1987 stock market crash, almost 50% in 1973–74, and nearly 50% in the early 2000’s — declines which the weird portfolio barely participated in.
Reflektion
Min egen reflektion är att det alltid är klurigt när man bygger en portfölj bara på backtesting. Å andra sidan kan jag se dragen i portföljen från t.ex. Harry Brownes Permanent-portfölj (min RikaTillsammans-portfölj). Det vill säga att jag gör en hel del av de antagandena också. Min fallgrop är att jag börjar ha åsikt om potentialen i t.ex. fastigheter, men jag ifrågasätter t.ex. inte potentialen i aktier på samma sätt.
Så, vad tänker vi?
