Introduction
I spent whole day to listen the audio book lasting three hours. I enjoy the time to sit at home and spend time to listen and think about the content. But I like to find some notes through the internet.
Article to read
Here is the article to read.
My most favorite learning is here:
Part III – On Investment Performance
10. On Revision to the Mean “Revision to the mean” is a statistical phenomenon that happens over and over again in all sorts of fields. Basically, it means that you might be able to select a small set of stocks that does better than the market over some period of time, but over a long period any set of stocks will eventually move towards the market average. This means you might be able to find a fund that beats the market for a year or two, but over the long haul, it will eventually match the market. When you add in the costs to this picture, it becomes clear what the benefit of a low-cost fund is.
