S&P 500 closes at record high, AI stocks rebound 30% and earnings grow 50% YoY – see the key numbers and what to watch next.

The S&P 500 closed at a fresh all‑time high on Friday, buoyed by a sharp rebound in AI‑related shares and the strongest earnings growth seen in a modern bull market, signaling a potential catalyst for the next trading session【1】.

| At a glance | |
|---|---|
| Index | S&P 500 record close |
| AI rally | SanDisk up >30% week‑over‑week |
| Earnings growth | Avg. S&P 500 earnings +50% YoY |
| Market reaction | All three major indexes up ~1% weekly |

## Record index close and AI bounce back  
The S&P 500’s record close came after the “AI trade” revived, with SanDisk posting a weekly gain of more than 30% – its biggest rally since January【2】. This rebound followed a late‑July tech sell‑off triggered by the collapse of an over‑leveraged hedge fund, which had temporarily depressed AI‑heavy names. The rally was confined to AI stocks, while the broader market saw modest weekly gains of about 1% across the Dow, S&P 500, and Nasdaq【2】.

## Earnings season fuels optimism  
By Friday, roughly 90% of S&P 500 constituents had reported Q2 results, delivering an average earnings increase of over 50% year‑over‑year—the highest growth rate recorded during a period of economic expansion【2】. Analysts note that such earnings momentum is unprecedented outside of recession‑bounce periods, reinforcing the view that the recent market strength is rooted in real profit growth rather than speculative hype【2】.

## What to watch  
- **U.S. retail sales data**: The July reading is slated for 8:30 a.m. on “Squawk Box,” with consensus at 0.1% versus 0.2% a month earlier【1】.  
- **Iran‑Strait of Hormuz developments**: Ongoing geopolitical tension could affect oil prices, which closed the week at $82 per barrel, $5 higher than the prior week【2】.  
- **AI earnings reports**: Upcoming results from major AI chip makers will test whether the sector’s bounce is sustainable.

The convergence of a record‑high index, a resurgent AI rally, and historically strong earnings suggests that market momentum may persist, but the next data releases and geopolitical headlines will be critical in confirming the durability of this upside.
