The Intelligent Investor - Jason Zweig WSJ
"All this puts me in mind of an old Wall Street proverb: "Bulls make money, bears make money, but pigs get slaughtered."
Versions of the saying have been circulating since 1905, according to lexicographer Barry Popik. The general idea — you can make money being optimistic, you can make money being pessimistic, but you'll be wiped out if you get too greedy — has probably been around for millennia.
My favorite modern version of the saying comes from the financier André Kostolany: "I can’t tell you how to get rich quickly. I can only tell you how to get poor quickly: by trying to get rich quickly."
It can pay to be a bull, and it can pay to be a bear. But it's always dangerous to be a pig, and there's no better time to remember that than December."
