valuations dont mean squat when shareholders havent got the capital to support the sp.
even the company cant support the sp.
the sp is controlled by speculators and traders, they pump cash in and out extracting a couple of percent here and there.
good news and bad news is the currency that these folks look for and nzo has delivered.
buybacks are are waste of money, much better to give divis to support the shareholder rather than play into the hands of traders.
