Negative 10 Yr Us Treasury?

[wescobrk]

Buffett has said if interest rates stay where they are over a long period of time then stocks are very cheap.

My question is if the 10 yr Treasury goes negative in the near future, for those that understand this bizarre world of people laying money out now to governments to receive less in the future, in this type of world would logic not dictate that equities are then ridiculously cheap? Is is that easy to answer the question, correctly?
