There is one more - pigs - so called because they are greedy pigs...  but, pigs are intelligent creatures, and they do not just thinkthe price may go down or think the price may go up, but theyknow it will do both...   which is a grat thing to know  only problem is pigs think that they
are more intlligent than both the Bulls and the bears... but in reality how often do you see a Bull or a Bear on a dinner plate?  pigs on the other hand nearly alway get slaughtered.  Quite a lot of the people claiming to be bears are in fact pigs dressed up as bears.
