S&P 500 ends flat, Brent oil slides below $90 on a pause in U.S.-Iran fighting; chip stocks keep Nasdaq down, Fed meeting ahead.

The S&P 500 closed essentially unchanged on Friday while Brent crude slipped below $90 a barrel after a reported pause in hostilities between the United States and Iran, a move that failed to spark a broader market rally as semiconductor stocks continued to weigh on the Nasdaq【2】.

## Oil price dip and market reaction  
Brent oil posted its biggest daily drop in more than three months, falling below $90 per barrel after investors cheered a pause in the U.S.-Iran conflict【2】. The decline removed a key inflationary pressure, yet the broader equity market did not rally; the Dow Jones Industrial Average rose over 250 points, but the Nasdaq Composite slipped lower as semiconductor names such as Micron, Marvell and AMD pulled the tech‑heavy index down【2】. The S&P 500 therefore finished the session near flat, reflecting a split reaction between defensive sectors and the lingering weakness in AI‑related chip stocks noted earlier in the week【1】.

## Earnings backdrop and policy uncertainty  
The week ahead is packed with earnings from major hyperscalers—Amazon, Meta, Microsoft, Apple, and Qualcomm—whose results will test the “AI spenders punished, chip makers rewarded” dynamic that has dominated recent market narratives【1】. At the same time, the Federal Reserve’s FOMC meeting on July 29 will decide whether to raise rates, with fed‑funds futures indicating a 35% chance of a 0.25‑point hike as early as next week【1】. Both the earnings calendar and the potential policy shift add volatility to the market, underscoring why the S&P’s flat close is more a pause than a trend reversal.

## Sector contrast: chips vs. megacaps  
Semiconductor ETFs posted gains earlier in the week, but individual chip stocks have turned negative, dragging the Nasdaq down despite a broader rally in the Dow【1】. Analysts note that the semiconductor rally hinges on continued AI spending from megacap hyperscalers; however, recent earnings commentary from Alphabet raised concerns about cash‑flow constraints and the lack of clear ROI on AI investments, prompting investors to shy away from the big AI spenders【1】. This tension explains why the S&P 500 can hold steady while the Nasdaq remains vulnerable.

## What to watch  
- **July 29 Fed meeting:** Any rate hike or forward guidance could shift bond yields and equity valuations.  
- **Hyperscaler earnings:** Amazon, Meta, Microsoft, Apple, and Qualcomm reports will test the durability of AI‑driven spending trends.  
- **Oil price stability:** A sustained dip below $90 could ease inflation expectations, while a rebound above $100 would reignite commodity‑driven risk.  

The flat S&P 500 underscores a market caught between easing geopolitical tension and lingering concerns over AI‑related cash use, leaving the direction of equity performance hinged on upcoming earnings and the Fed’s policy decision.
