U.S. stocks moved higher Wednesday as investors looked to the afternoon release of the Federal Reserve minutes from the central bank's October meeting. 
The S&P 500 rose 0.51%, the  Dow Jones Industrial Average gained 0.52%, and the  Nasdaq climbed 0.54%.

The Fed opted to leave rates unchanged at its last meeting, though signaled that an interest rate hike in December was still in play. The minutes will be closely scrutinized for clues as to the likelihood of a year-end hike.

"We'll be looking for signs that Fed officials were looking for incoming data to continue its improved trend as a sine qua non to any rate hike in December," Christopher Vecchio, currency analyst at DailyFX, wrote in a note.

Three Fed officials backed a rate hike sooner than later in separate speeches Wednesday morning. Atlanta Fed President Dennis Lockhart, a voting member on the Fed's policy committee, said that international market volatility has calmed since the October meeting and that continued improvement in the labor market supported a rate hike.

Separately, Cleveland Fed Present Loretta Mester said that a small rate hike at the next meeting would not harm the economy, while Richmond Fed President Jeffrey Lacker also said he backed an interest rate move.

The housing market showed a rare sign of weakness in October after construction on new U.S. homes slid 11% to an annual rate of 1.06 million, according to the Commerce Department.

However, permits for new construction climbed 4.1% to 1.15 million, signaling that demand will pick up in coming months.
