Stock index futures pointed to a lower open Wednesday with tech dragging after Microsoft sounded concern on top-line outlook.

Nasdaq futures (NDX:IND) -1.2% were the weakest, with S&P futures (SPX) -0.8% and Dow futures (INDU) -0.7% also in the red.

Microsoft (MSFT) fell 2% premarket, reversing its post-earnings pop after CFO Amy Hood said on the conference call that “moderating consumption growth” in the cloud business would likely extend into current fiscal Q3. MSFT guided for quarterly revenue of $50.5B to $51.5B, about $1B shy of the Wall Street consensus.

The caution on the cloud had a knock-on effect on Amazon (AMZN), which was down 2% before the bell. Also in megacap land, Tesla (TSLA) reports its earnings after the bell today.

Rates were lower. The 10-year Treasury yield (US10Y) fell 3 basis points to 3.43% and the 2-year yield (US2Y) fell 6 basis points to 4.15%.

“There’s been a little bit of a bias towards risk-off sentiment over the last 24 hours, thanks partly to some weaker-than-expected earnings releases that added to growing concerns about a potential US recession,” Deutsche Bank’s Jim Reid wrote.

The economic calendar is fairly empty and traders will be positioning for GDP on Thursday.
