On Wednesday investors await the pending home sales index. Released by the National Association of Realtors at 10 a.m. ET, the pending home sales index for November is expected to rise 0.5% month over month. The index tracks homes for sale that are under contract waiting for the transaction to close. In the prior month of October, the index rose 0.1% to 110. Investors will be also watching to see if the Dow Jones Industrial Average hits the symbolic 20,000 threshold. The index narrowly missed the milestone on Tuesday.
