It's B-Day.
Federal Reserve chairman Ben Bernanke takes center stage Wednesday. At a highly anticipated afternoon press conference, he's expected to discuss when the central bank could begin tapering the pace of its bond purchases.
The Fed's bond-buying program has been a boon to equity markets, supporting U.S. and global stock indexes and driving them to recent record highs.
Any comments from Bernanke suggesting that the program's end is near would likely lead to significant declines.
"Bernanke has to address asset purchases and every nuance in his replies will be seized upon by markets," said Deutsche Bank economist Jim Reid, in a research note.
Bernanke is scheduled to speak at 2:30 p.m. ET, following the conclusion of the Fed's latest two-day monetary policy meeting.

U.S. stock futures were little changed early Wednesday. But stocks rose for a third day in a row on Tuesday.
"Investors this week have scaled back expectations of an immediate unwinding of stimulus by the Fed, hopeful that the patchy run of data from the U.S. economy will prevent a reduction in asset purchases in the near term," said Ishaq Siddiqi, a market strategist at ETX Capital in London.
