It sort of called the bull market in tech stocks in 95 or so or whenever it started. When I was working as a lawyer. I read a long article about sun microsystems and silicon valley in the economist. Within two weeks all the other mags had similiar articles and I then tech stocks exploded. Back then the economist seemed to lead the other mags on issues by about 2 weeks. I do not know if still holds true.
I also know two people who listened to me when I told them what I had read. One of em was my friend a stock broker. He had no personal money, like me at the time, but his clients did well after his economist picks and he did win the office stock picking competition for new golf glubs. The other person who listed to me (the economist) turned 800 in 3.5 million and then turned it into 1.5 and bouncing around as we speak.
