Time to short the US/Yen?

Interesting comment on CNBC if you think you may be ready to dip your toe into shorting the Greenback against the Yen. The S+P is down around 14 points right now and the AD line is 1/9 winners to losers BUT the down to up volume is only 1 to 4. This could be consistent with a market that may get better by 4:00.
