MSFT rally set for Russell reshuffle as AI spending jitters hang over stock

NEW YORK, June 28, 2026, 12:01 PM EDT

  • Microsoft Corporation jumped 5.71% to $372.97 on Friday. Trading volume soared to 186.2 million shares, close to 4.8 times its 65-day average.
  • Microsoft shares got a lift Friday as Russell index rebalancing shifted the stock into both growth and value indexes. That change can cloud real demand since index flows boost volumes.
  • Microsoft is heading into a post-rebalance Monday session and wraps up its fiscal year on June 30. The company hasn’t set a date yet for its fiscal Q4 earnings.

Microsoft Corporation heads into the week with its price picture looking clearer, but market signals stay muddled.

The stock climbed $20.14 Friday, ending the day at $372.97. That comes after shares hit a 52-week low of $349.20 on Thursday. Trading volume jumped to 186.2 million shares, about 478% of the 65-day average. Still, the stock is down 22.88% this year.

Friday wasn’t an average session. The FTSE Russell reconstitution kicked in after the close, putting Microsoft in both the Russell 1000 value and growth indexes, not just growth. Steven DeSanctis at Jefferies called it a “really massive trade.” Melissa Roberts from Stephens said it was a “key liquidity day.” Reuters

Microsoft ended the week higher, despite a rough run on most days. The company’s stock dropped on Monday, bounced Tuesday, slid for the next two sessions, and then jumped on Friday. Shares finished up about 1.5% from Monday’s close to Friday. Versus the close on June 18 before the week began, though, Microsoft was still off around 1.7%.

S&P 500 dropped 0.05% Friday, closing the week down 2.05%. Nasdaq declined 0.24% on the day and slid 4.7% for the week. U.S. exchange volume was high at 30.1 billion shares, topping the 20-session average of 23.1 billion. David Stubbs, chief investment strategist at AlphaCore Wealth Advisory, said “questions around profitability and the capex story” persist. Reuters

Capex now hangs over Microsoft. The April quarter had revenue at $82.9 billion, up 18%, with Azure and other cloud services jumping 40%. Microsoft Cloud brought in $54.5 billion, 29% higher, but Microsoft said Cloud gross margin dropped to 66% as AI infrastructure and AI use drove costs higher.

Microsoft CEO Satya Nadella told analysts its AI unit has hit $37 billion in ARR, up 123%. CFO Amy Hood said 2026 capital spending is set around $190 billion and expects the company to be capacity-constrained through 2026.

Microsoft faces a key test this week—not just if it can notch another heavy-volume up day, but if buy interest sticks after the rebalance flows finish. Monday will make that clear. The session should separate the index fund buying seen Friday from investors stepping in for Microsoft’s lower price as AI spending climbs.

June 30 is the end of Microsoft’s fiscal year. The company said it will report fiscal Q4 earnings soon after the market closes, without giving a date.
