FYI: .Investment newsletters and their marketing do not always tell the truth about the returns. Warren Buffett’s return since the 1960s provides a reality check on the advertising claims you might see.
.Only a small fraction of the top-performing newsletters for a given period of time remain in the top-performing group during the subsequent period. Where persistence may exist is at the bottom of the rankings with terrible performers having an above-average chance of remaining terrible.
.A common trait among those newsletters that have been around for a long time is their willingness to stick with their approaches, even when the strategies haven’t worked. This behavior has likely contributed to their good long-term performance
