Workday shares jump 18% after takeover talks, while the S&P 500 closes at a record 7,798.99 following a flat July PPI and modest CPI, easing rate‑hike worries.

The S&P 500 closed at a fresh all‑time high of **7,798.99**, up **0.7%**, as July producer‑price data came in flat and a Reuters report sparked an **18% surge in Workday stock**【1】. The move eased market concerns about another Federal Reserve rate hike in September.

## Inflation data and market reaction  
July’s producer‑price index (PPI) showed **no change month‑over‑month**, missing the 0.2% rise economists had forecast【2】. Core PPI, which strips out food and energy, rose **0.2%**, also below the 0.3% consensus. The flat headline PPI followed a July CPI that rose **0.1%**, exactly on target【2】. Together, the milder readings trimmed expectations for a September rate increase, with CME’s FedWatch tool showing the probability of a steady‑rates decision falling to **35%** from 40% earlier in the day【1】.

Equity indices responded positively: the S&P 500 added **0.65%** to breach the 7,800 barrier for the first time, while the Nasdaq gained **0.81%** and the Dow edged up **0.13%**【2】. Treasury yields slipped, with the 10‑year yield falling to **4.65%** from 4.67% before the data【1】, reflecting reduced demand for higher‑rate‑sensitive bonds.

## Workday’s breakout and sector dynamics  
Workday (WDAY) surged **18%** after Reuters reported that private‑equity firm Silver Lake was in talks to acquire the HR‑software company【1】. The jump made Workday the top performer on both the S&P 500 and Nasdaq 100 for the session. Despite the rally, Workday remains **more than 3% below its year‑to‑date peak**【1】. The broader technology sector also posted gains, with memory‑chip stocks like SanDisk and Western Digital rising 4%‑14% and the “Magnificent Seven” largely in the green, except Nvidia【1】.

## What to watch  
- **July CPI release** (expected later today) – a further deviation from expectations could shift Fed rate‑hike probabilities.  
- **Federal Reserve meeting** on September 17 – the decision will hinge on whether inflation continues to moderate.  
- **Workday earnings** (next quarter) – performance relative to the takeover speculation will test the stock’s sustainability.

The record‑setting S&P 500 underscores how a modest easing in inflation can revive equity buying, but the market remains sensitive to any shift in the Fed’s policy outlook and to corporate‑specific catalysts like Workday’s potential acquisition.
