Berkshire B - Next stop at?

I am willing to invest in this value share but really... I have no clue as to where it is going. Is it a buy or is it going down?

The chart says a good short will give you a huge profit. But... this is Warren Buffet. Is it his moment of truth?
I am going in with my paper trading account for a long. historically it should go up. But the current situation in US says auch.
Who can shed a light on the next election results in favor of Liberals? What would possibly be the effect on this share.

BTW I m a noob. Just started. But I want to go long on this one.
