The S&P 500 Index remains under pressure this month, and this week’s events will determine whether it will bounce back. It was trading at 7,457 points, down by 2.10% from its highest point this year. This article highlights some of the key catalysts that will drive the SPX and VOO ETFs this week.

S&P 500 Index to react to key earnings

A key driver for the S&P 500 Index this week will be corporate earnings by some of the biggest American companies. While some large companies will publish on Monday, the most important ones to watch will report on Wednesday. 

Tesla and Google, two members of the Magnificent 7, will release their numbers on Wednesday. These results come at a time when most companies in the group have pulled back substantially.

GE Vernova, Philip Morris, Texas Instruments, AT&T, and Moody’s will release their numbers on Wednesday. A day earlier, companies like Charles Schwab, Chubb, Danaher, General Motors, and Northrop Grumman will publish their numbers.

Other companies that will release their numbers on Thursday are Intel, T-Mobile, Raytheon, Blackstone, Honeywell, Newmont Mining, and Lockheed Martin.

The earnings season has started well, with the top banks like Goldman Sachs, JPMorgan, Morgan Stanley, and Citi benefiting from large IPOs and trading activity. FactSet data shows that the earnings growth so far stands at 24.2%, higher than the expected 23%.

Of course, there were some disappointments, including Netflix and IBM. IBM stock plunged by over 20% in a day after the company warned about its growth as companies prioritized hardware spending. Netflix, on the other hand, started to withdraw key data, suggesting that its business was slowing.

Escalating US and Iran crisis

The S&P 500 Index will also react to the escalating crisis in the Middle East, where the US and Iran launched deadly attacks during the weekend. The US hit some major targets, including civilian infrastructure, leading to tens of deaths. 

Iran also launched attacks against US targets, killing two people and injuring more others. In a statement, the Supreme Leader warned that the crisis will escalate further, pointing to the unreliability of Trump’s signature.

Crude oil prices have continued rising in the past few days, with Brent and WTI nearing $90. As such, there is a risk that the rising oil prices will lead to higher inflation. Data released last week showed that the headline consumer inflation eased to 3.5% in June from the previous 4.2%. 

South Korean and AI jitters

The other key driver for the S&P 500 Index will be the happenings in South Korea, a country that has experienced substantial volatility in the past few weeks. KOSPI, its main benchmark, has dropped by over 20% from its highest point this year.

South Korea’s markets were closed on Friday, and traders will watch how they open on Monday. A plunge in key companies like Samsung and SK Hynix will likely drive US semiconductor and memory names lower.

Traders will also be on the lookout for the latest developments in China, where some companies have launched more advanced models. On Friday, top US stocks plunged after China’s Moonshot released the Kimi K3 model, which is beating popular US models like Claude and ChatGPT.

As the second-quarter earnings season of 2026 approaches its most critical stretch, the global equity market finds itself at a pivotal crossroads.

For over two years, a relentless, AI-driven bull run has propelled mega-cap technology valuations to historically elevated levels.

However, the narrative on trading desks has undergone a fundamental shift. The era of rewarding companies simply for uttering the words “artificial intelligence” is officially over.

As Alphabet, Microsoft, Meta, Amazon, and Apple prepare to open their books between July 22^nd  and July 30^th, Wall Street is demanding concrete evidence of monetization.

Investors are no longer grading on a curve; they want to see the receipts.

Big tech earnings ahead: the $725 billion arms race

The defining metric of this entire reporting cycle will undoubtedly be capital expenditure (capex).

The sheer scale of infrastructure investments being deployed by the four major US hyperscalers – Amazon, Microsoft, Alphabet, and Meta – has reached eye-watering proportions.

According to updated consensus data, their combined capex guidance now sits at an unprecedented $725 billion for the current year, representing a staggering 77% increase from 2025.

2026 projected capex commitments:

Amazon: ~$200 billion

Microsoft: ~$190 billion

Alphabet: $180 billion – $190 billion

Meta Platforms: $125 billion – $145 billion

This staggering allocation of capital into graphics processing units (GPUs), power grids, and massive data center footprints has triggered intense anxiety among institutional allocators.

While this structural build-out serves as a massive secular tailwind for hardware providers like Nvidia (which won’t report its data center metrics until August 26), it places immense pressure on the software and cloud giants to prove this capital is yielding high-margin returns.

A guidance cut this week would signal weak underlying enterprise demand – while an unbacked increase in spending without a corresponding bump in revenue could spark a sharp margin-driven sell-off.

The reporting calendar: key dates and battlegrounds

The heavy lifting begins next week, with the market tightly focused on three specific reporting windows:

• July 22, 2026 (Alphabet): Google’s parent company kicks off the gauntlet alongside Tesla. Alphabet’s Q1 results saw Google Cloud revenue expand by an astonishing 63% year-on-year to hit $20 billion, boasting a record 32.9% operating margin. Wall Street is looking for Q2 revenue to hit roughly $116.8 billion. The core focus will be whether Google Cloud can sustain its 63% growth crown or if aggressive new market entrants have begun eating into its enterprise pipeline.
• July 29, 2026 (Microsoft & Meta): Microsoft will present its fiscal fourth-quarter results, where any print for Azure growth below 35% will likely be treated as a severe deceleration. Simultaneously, Meta will need to prove that its $125 billion+ capex is continuing to optimize its ad-targeting engine and drive top-line growth to offset the massive cash burn of its infrastructure layer.
• July 30, 2026 (Amazon & Apple): Amazon is expected to print revenue near $196 billion, with the market hyper-focused on AWS margin expansion. Apple will report its fiscal third-quarter numbers with an estimated revenue of $108.9 billion. Apple presents a fascinating contrarian play; by leveraging an installed base of over 2.3 billion active devices to deploy “Apple Intelligence,” it is executing a capital-light AI strategy that insulates its margins from the data center spending war engulfing its peers.

Cloud growth: The ultimate litmus test

Because cloud infrastructure is where enterprise AI demand materializes first, the sequential and year-over-year growth rates of Azure, AWS, and Google Cloud will serve as the market’s ultimate truth mechanism.

Investors are highly attuned to the risk of a “margin squeeze” – a scenario in which heavy depreciation costs from newly built data centers kick in before corporate clients scale up their paid software seats and API usage.

A note of caution was already introduced to the broader tech sector following IBM’s earnings miss on July 14^th, which triggered a sharp one-day decline.

While analysts isolated that specific event to hardware supply-chain timing rather than systemic weakness in macro AI demand, it illustrated just how fragile investor sentiment has become.

With valuations priced for perfection, the upcoming multi-day stretch will decide whether Big Tech’s massive architectural bets can sustain the next leg of the macroeconomic expansion, or if the market is due for a harsh reality check on the actual velocity of AI monetization.
