Morgan Housel is one of my favorite writers in all of finance. He had this to say on what makes an investment article great.
Morgan believes that the best posts are evergreen and I totally agree. One of my favorite pieces of all time comes from Jason Zweig, written in 2001. This post will be just as powerful fifty years from now as it is today.
Since turnover is negatively correlated to investment performance, no post that stands the test of time will include trade setups or forecasts. In my writing, nothing is particularly actionable, but hopefully it is thought provoking because for 99% of investors, more good comes from thinking then from acting.
