Not only because he is a notorious bear in certain markets when everyone else turns into greedy freaks, but because he says stuff like this:
“The key to investing is not assessing how much an industry is going to
affect society, or how much it will grow, but rather determining the competitive
advantage of any given company and, above all, the durability of that
advantage.” – July 1999 at Herb Allen’s Sun Valley, Idaho Retreat
Words to live by.
