The first week of September 2026 opened with a rally that faded by Thursday’s close, as a hotter-than-expected jobs report on September 3 fueled speculation that the Federal Reserve could raise interest rates at its September 17 meeting. The S&P 500 gave back early gains, and the pullback aligned with a seasonally weak stretch — September has historically been the worst month for equities. With the long Labor Day weekend ahead, traders closed positions, leaving the market to digest a familiar mix of earnings-driven moves and macro anxiety.
Cybersecurity Stocks Take Center Stage in Upgrades
One of the clearest trends this earnings season has been the analyst community’s enthusiasm for cybersecurity names. Thomas Hughes of MarketBeat noted that the five most-upgraded stocks in the S&P 500 during this reporting period were all in the cybersecurity sector, reflecting a surge in demand tied to the rise of agentic AI — systems that act autonomously and require new layers of protection.

Palo Alto Networks (NASDAQ: PANW) stood out among them. Hughes acknowledged that the stock carries a premium valuation, but pointed out that the company’s growth is accelerating, prompting analysts to raise price targets to all-time highs. The market’s appetite for cybersecurity names was also visible in Rubrik (NYSE: RBRK), which operates in the data security niche. Rubrik shares have climbed roughly 150% since April, though Hughes cautioned that the stock now carries meaningful valuation risk after a sell-the-news reaction to its latest earnings.
Apple, Salesforce, and the AI Infrastructure Trade
Apple Inc. (NASDAQ: AAPL) is set to hold its annual product event on September 9, and speculation has centered on a possible foldable iPhone. Sam Quirke noted that while consumers and analysts are bullish on the prospect, investors may be more focused on other factors — including services growth and China demand — that could have a larger impact on the stock’s direction.

Salesforce (NYSE: CRM) has been one of the best-performing large-cap tech stocks since June, but Quirke warned that after a stellar earnings report, the shares look overbought. He suggested that investors might want to wait for a pullback before adding exposure.
In a separate piece, Quirke examined Amazon.com Inc. (NASDAQ: AMZN) and its early-stage Project Tetromino, an initiative aimed at automating last-mile delivery. The project, if successful, could improve margins for a company that is increasingly focused on operational efficiency.
Eli Lilly Expands Beyond Obesity, Copper Rallies on AI Demand
Eli Lilly & Co. (NYSE: LLY) announced its intention to acquire Merida Biosciences, a move that expands the company’s portfolio in serious autoimmune and allergic diseases. Chris Markoch highlighted the key drug candidate Lilly is targeting and noted that the deal underscores the company’s strategy to build a broader pipeline beyond its blockbuster obesity treatments.
Markoch also covered the surge in copper prices, which have been lifted by a combination of trade-policy shifts and structural demand from the artificial intelligence infrastructure boom. He highlighted three copper producers at the center of the trade, and separately pointed to three AI infrastructure stocks that are foundational to every data center project — a sector that is becoming a flashpoint in the midterm elections, though construction continues unabated.
Software Stocks Recover, Broadcom’s Guidance Puzzle, and Retail Earnings
Ryan Hasson reported that this earnings season may have finally quelled fears of a ‘SaaS-pocalypse’ in software stocks. With capital rotating back into the sector, he identified five software names that are likely to outpace the recovery. Hasson also spotlighted Lumentum Holdings (NASDAQ: LITE), a leader in optical connectivity that has been one of the S&P 500’s top performers this year, and AeroVironment (NASDAQ: AVAV), which announced a landmark U.S. Army contract just before its September 9 earnings report.
Leo Miller analyzed Broadcom’s (NASDAQ: AVGO) earnings, where headline numbers were strong but guidance disappointed. The company explained that the weak outlook was due to a supply issue, and that AI demand actually exceeds what its guidance implies. Miller also wrote about insider buying, highlighting three companies where management has been increasing stakes, and covered three dividend raisers, including a dividend king.
Nathan Reiff explored the false choice between stability and growth, highlighting three stocks with long-term catalysts that mitigate cyclical volatility. He also examined IonQ (NYSE: IONQ), which is employing defense and national security contracts to expand beyond quantum computing, and Qualcomm (NASDAQ: QCOM), where automotive and AI growth may be the long-term story, but smartphone trends remain the best near-term indicator.
Dan Schmidt reviewed retail earnings, which were mostly strong, and noted that Ulta Beauty (NASDAQ: ULTA) — which didn’t make the list of notable names — may deserve a closer look after a post-earnings sell-off that appears overdone. Jeffrey Neal Johnson covered the U.S. Department of War’s pursuit of a roughly 35% stake in Venezuelan oil rights, a move that could be bullish for U.S. oil supermajors, and NVIDIA’s (NASDAQ: NVDA) $3.5 billion investment in MediaTek, which is part of its strategy to defend its accelerated computing franchise against custom silicon. He also noted that a $700 million NASA contract awarded to Blue Origin could provide a catalyst for space stocks.
What to Watch Next Week
The market’s next major test comes with the release of August inflation data, due out mid-week. If the report shows price pressures cooling, it could ease rate-hike fears. If it runs hot, the September pullback could deepen. Meanwhile, Apple’s September 9 event and earnings from AeroVironment and other companies will provide fresh catalysts. The AI trade remains the dominant force in equities, but as this week showed, even the strongest trends are vulnerable to macro shocks and seasonal headwinds.
