Apple and Tesla Popularity: Its in our DNA to buy high and panic

Behavioral Finance explores the concept of why we are wired to make the same mistakes over and over as a species. Recently, I started reading a book called "Popular" by Mitch Prinstein , where he discusses that its in our DNA to helps us survive. We have done better by doing popular things in nature. When we go with the flow of the group and hunt together and fight together, we live better. Those outcasts who go against the group are shunned and then removed. In finance however, our popular instincts may conflict at times with our investment selection choices.
