A sprinkling of deal news, sinking oil prices and a firmer dollar are in the background as stocks edge higher Tuesday.
The big news for markets though will come in the Federal Reserve's meeting minutes, set for release at 2 p.m. ET. The minutes of the September 18 meeting and the August 16 call will be released. Traders are watching for hints of what made the Fed take the aggressive step to slash the Fed funds rate by a half point, greater than the 1/4 point widely expected.
