1. Bank earnings: Bank of America and Goldman Sachs will report quarterly results ahead of the open.
Investors expect the two banks to report huge one-time hits to their profits because of changes to U.S. tax rules.
Goldman warned in late December that the recently approved tax law would knock $5 billion off its earnings.
Citigroup posted an $18.3 billion loss on Tuesday, taking a $22 billion charge because of the tax cut.
Many firms are adjusting the value of so-called deferred tax assets because the corporate tax rate is going down. Some also face a one-time tax on their overseas earnings. Still, the new tax law is expected to be a boon for banks over the long term.
