U.S. stock index futures were slightly higher Wednesday morning, as market participants continued to try to come to terms with a sharp shift in bond markets.
At around 4:00 a.m. ET, Dow Jones Industrial Average futures rose 34 points, indicating a positive open of more than 33 points. Futures on the S&P 500 and Nasdaq Composite were both seen marginally higher.
Wall Street's main indexes registered solid gains in the previous session, but finished below their session highs in a reflection of the underlying concerns about the economic outlook.
Last week, the yield on the 10-year U.S. Treasury bill fell below that of the three-month note for the first time since 2007. It's a development that investors call an inverted yield curve and is seen as an early indicator of a recession.
