Bear

In Yellowstone, it means one thing. On Castro Street in San Francisco, it means another. But on Wall Street, a Bear is a Dour Dan, a Sad Sadly, a Negative Nancy. A bear believes that things will get worse, that the market will go down, and that the glass really is half empty and, uh...has germs on its rim.

So why a bear?

Because it's strong. And the sad backstory is that its counterpart, Positive Polly, is a bull. Bored (presumably stoned) miners in California used to pit the two animals against each other in a ring, and whoever won, well, more or less determined the future of the markets. It was that era's crystal ball, albeit with blood all over it. Think: Punxsutawney Phil with deadly powers. Where was PETA when we needed them?
