The Bank of Japan has pushed interest rates below zero, sending Asian stocks and U.S. Index futures sharply higher overnight. The exuberance is all but certain to be short-lived, however, given Europe’s failure to induce economic growth with negative rates, and the fact the 25 years’ worth of stimulus have failed to lift Japan from its deflationary wallow. Hope springs eternal, of course, although not in this case.  No investor could actually believe that BOJ’s move will accomplish anything useful. They buy stocks anyway, certain that that’s how everyone else will react to the news.
