The stock market had a tough week but a great month. Here's what happened

The S&P 500 retreated from record highs on Friday, breaking a four-week winning streak, despite securing a strong 2% gain for August. This market softness was significantly influenced by Nvidia's post-earnings decline, as investors 'nitpicked' concerns over data center revenue and inventory despite robust guidance, with the $4.3 trillion market cap company dragging the broader index lower. While CrowdStrike delivered a clean beat and saw an upgrade, its shares also faced initial pressure. Concurrently, July's core PCE inflation rose 2.9% year-over-year, its highest since February, though the market still anticipates a September Fed rate cut following Chairman Powell's recent dovish signals, setting up a potentially volatile September, historically a weak month for equities.

Analysis

The U.S. equity market is exhibiting signs of fatigue, with the S&P 500 retreating from a record high to break its four-week winning streak, despite closing August with a 2% gain. This downturn is significantly influenced by post-earnings weakness in Nvidia (NVDA), which fell despite strong results and guidance. Investor concerns, focused on a slight data center revenue miss, inventory increases, and customer concentration, drove the $4.3 trillion company's stock down over 2% for the month, weighing on the broader index. In contrast, the cybersecurity sector showed resilience; CrowdStrike (CRWD) delivered a clean earnings beat and received an analyst upgrade, overcoming initial pressure from its revenue guidance to finish the week higher. Similarly, Palo Alto Networks (PANW) recovered from an M&A-related sell-off after its earnings report dispelled concerns about its core business strength following the $25 billion CyberArk acquisition. This mixed corporate picture unfolds against a cautious macroeconomic backdrop, where the core PCE price index rose to a 2.9% annual rate, its highest since February. Despite this, market expectations remain anchored to a Federal Reserve interest rate cut in September, following Chairman Powell's dovish pivot at Jackson Hole, setting up a potentially volatile month historically known for equity weakness.

Key Decisions for Investors

• Given the S&P 500's retreat from highs and the market's entry into a historically weak September, investors should consider trimming positions in high-flying stocks to lock in profits and manage potential volatility.
• For Nvidia (NVDA), the negative market reaction to a strong report signals a critical juncture; investors must weigh whether concerns over inventory and customer concentration are valid risks or if the pullback presents a compelling entry point based on its rosy guidance.
• The resilience in cybersecurity stocks like CrowdStrike (CRWD) and Palo Alto Networks (PANW) post-earnings suggests sector strength, making any price weakness a potential buying opportunity for those with a bullish view on enterprise tech spending.
• Monitor upcoming earnings from Broadcom (AVGO) and Salesforce (CRM), as well as the Federal Reserve's September meeting, as these events will serve as key catalysts for market direction amid conflicting signals from inflation data and monetary policy expectations.
