Obamacare is still mess and Washington, D.C., continues to be consumed by gridlock, but the Dow Jones Industrial average doesn’t seem to notice.

Indeed, after months of posting major gains and suffering a few setbacks, the Dow closed Wednesday at an all-time high of 15,746.88.

The Dow increased Wednesday by 128.66 points, or 0.8 percent:

Meanwhile, the Nasdaq composite fell 7.92 points, or 0.2 percent, to 3,931.95. The index reached a 13-year high at the end of last month.

In government bond trading, the yield on the 10-year note fell to 2.65 percent from 2.67 percent on Tuesday. The U.S. Treasury said Wednesday it will begin selling Treasury securities next year that have variable interest rates. It's the first new Treasury security in 17 years.
