Stock futures are higher Wednesday morning as shares of technology companies surge after strong earnings reports, putting major indexes on track to add to record highs.

The Dow Jones rose 280 points Wednesday on a surprise ADP jobs report. A speech from Fed chief Powell is next. Salesforce soared on earnings.

The well-received results from Salesforce.com are having an outsized impact on the Dow -- the software maker's current premarket price equates to a 273-point boost to the blue-chip index, which remember is price-weighted.
