Futures falter on Asian weakness

U.S. index futures are again flirting with limit down moves early this morning as overseas markets are reeling.  The Hang Seng lost over 12%, and the Nikkei marked its lowest close in 26 years.  The Japanese yen has surged 10% against the dollar in just a week, rising to a nearly 13-year high of 92 yen to the dollar, rendering the exporting nation's products more expensive.  The yen's strength has been even more dramatic against the euro.  On October 14, a euro would buy 139 yen.  Two weeks later the same euro will get you 115 yen.  The dollar continues to strengthen against the euro, now trading at $1.24 each.
