The strong January ADP employment data before Wednesday's open goosed the already positive futures and helped trigger a 0.45% intraday high about five minutes into the session. The index then sold off to its -0.28% intraday low just before the lunch hour. It then traded in a fairly narrow range to the 2 PM release of the Fed minutes, which triggered a fast-trade head fake. The 500 closed the session with a minuscule 0.3% gain.
The U.S. Treasury puts the closing yield on the 10-year note at 2.48%, up three BPs from the previous close.
