Maybe someone can ring Warren Buffett to find out how he became one of the richest man in the world?

Does he need a computer? whatever technical analysis or fundamental analysis you're talking about....band or no band...

OR

He just make his own judgement to buy those companies that he strongly believes that have sustainable competitive advantages and future potential growth?

I think some of the long-term shareholders here just like Warren Buffett, when you buy shares you tend to keep for years/decades... I salute you!
That's how you become rich, richer and richest.....
