Wall Street was set to open higher on Tuesday after upbeat earnings from big U.S. banks and Halliburton, while investors awaited a speech from U.S. Treasury Secretary nominee Janet Yellen that is expected to advocate hefty fiscal spending. Shares of Goldman Sachs Group Inc added 2.5% as its fourth-quarter profit more than doubled, dwarfing estimates after another blowout performance at its trading and underwriting business. Bank of America also topped fourth-quarter profit estimates and joined JPMorgan, Citigroup Inc and Wells Fargo & Co in releasing some cash reserves to cover for coronavirus-driven loan losses, underscoring its confidence in the economy.
