Morgan Stanley Names Its Top Chip Picks for 2026: Nvidia, Broadcom, and Astera Labs

 Meta description: From an oil shock and a Fed scare to record-setting Big Tech earnings swings, July 2026 was one of the most volatile months in years — and stocks still ended it higher. Here's the full recap.

If you feel like you've lived through several distinct markets in the span of a single month, you're not imagining it. July 2026 delivered an oil shock, a Fed scare, a historic chip-sector selloff, and some of the most dramatic single-day stock moves in years — and yet, somehow, all three major US indexes still ended the month higher. Here's a look back at how we got here, and what it might mean heading into August.

How the month unfolded

July's volatility arrived in distinct waves, each of which we tracked in real time across our recent coverage:

• Geopolitical shock: Oil prices spiked above $100 a barrel amid escalating US-Iran tensions before crashing back down following a weekend pause in hostilities
• AI-spending anxiety: Alphabet and Tesla's disappointing capex-related reactions set off weeks of skepticism toward megacap AI infrastructure spending
• The chip-sector correction: Semiconductor stocks fell into a brutal multi-week slide, dragging the Nasdaq 100 into a technical correction and South Korea's Kospi down more than 25% from its June peak at the worst point
• The Fed scare: A rate hold that markets expected still triggered the Dow's worst single-day decline since April 2025, as 30-year Treasury yields spiked to their highest level since 2007
• The earnings whiplash: Meta and Apple both disappointed investors despite solid headline numbers, while Microsoft and Amazon delivered two of the largest single-day stock gains in market history
• The Kospi's historic reversal: South Korea's benchmark surged a record 17.9% in a single session Friday, capping the month's volatility with one final extraordinary swing

The numbers behind a genuinely strange month

Despite all of that turbulence, July closed with gains across the board. All three major US averages posted gains for the week ending July 31, and the Dow recorded a positive return for the month as well. The fact that a month featuring a technical correction in the Nasdaq 100, a 1,153-point single-day Dow drop, and a record-setting Kospi collapse-and-rebound still ended in the green is a useful reminder of how resilient headline index returns can be even when the underlying path is anything but smooth.

The theme that tied it all together

If there's one thread connecting nearly every major story this month, it's this: markets have become far less willing to reward AI infrastructure spending on its own, and far more focused on whether that spending is translating into actual returns. Alphabet, Meta, and Apple all learned this lesson in some form; Microsoft and Amazon showed what happens when a company can convincingly demonstrate the payoff. That distinction — not simply "AI spending good" or "AI spending bad" — looks set to remain the defining lens through which markets judge megacap tech for the foreseeable future.

What to watch heading into August

• Whether bond yields stabilize, given that 30-year Treasury yields ended July at their highest level since 2007 (covered in our companion post)
• Whether the chip-sector rebound holds, or whether "circular financing" concerns resurface once the excitement from this week's earnings fades
• How Apple's leadership transition unfolds, with incoming CEO John Ternus taking over September 1 following a rocky final quarter under Tim Cook
• Whether the Kospi can build on Friday's historic rebound or settles back into a lower trading range below its June highs
• Remaining earnings season data points, as more companies report and either reinforce or challenge the "growth over capex alone" pattern established this month

Bottom line

July 2026 will likely be remembered as one of the more genuinely volatile months for markets in recent years — not because of any single catastrophic event, but because of how many distinct, high-magnitude swings it packed into just four weeks. With bond yields elevated, AI-spending scrutiny still very much alive, and several major storylines still unresolved, August looks unlikely to offer the market much of a breather.
