Today's Primer Post

The U.S. stock market is coming off a losing week and three consecutive down sessions (a fractional gain by the S&P 500 last Wednesday notwithstanding) as investors continue to follow the saga of the "fiscal cliff" talks. House Speaker John Boehner has now offered the White House a concession on raising tax rates on the wealthy, but there's little indication as yet as to how this may or may not move the negotiations.

Only a few bits of economic data are on today's calendar, starting with the monthly Empire State Survey from the Federal Reserve Bank of New York at 8:30 a.m. New York time. That monthly measure of New York State manufacturing activity is expected to come in at -1.0 for December, a less negative reading than November's -5.2. At 9am ET, the Treasury will release the so-called "TIC" data, a measure of foreign investment in the U.S.

At 10:30 a.m., CNBC's Steve Liesman will have an exclusive interview with Richmond Fed President Jeffrey Lacker, who's been the lone dissenter to the Fed's monetary policy statements at the last few FOMC meetings.

There are no earnings reports of note on the calendar today, although later in the week we'll hear from Oracle (ORCL), FedEx (FDX), Nike (NKE), Research In Motion (RIMM), General Mills (GIS), and Discover Financial (DFS), among others.

Intel (INTC), Apple (AAPL), and Hewlett-Packard (HPQ) are among our stocks to watch this morning, as an International Trade Commission judge rules in favor of those three tech giants in a patent case.

Wal-mart (WMT) has cut prices on Apple products for the holiday season, including the third-generation iPad and the iPhone 5.
