On Monday, the U.S. stock markets exhibited a sense of calm as Wall Street approached the final phase of the second-quarter earnings season. This followed a week of turbulent trading, which was driven by growing concerns over a potential economic recession. Typically, trading volumes escalate during the period when the largest corporations in the United States disclose their financial results. However, the past month, and particularly the last couple of weeks, have been marked by unusual fluctuations in the stock market. The volatility index soared to its highest level since the early days of the Covid-19 pandemic, triggered by a disappointing employment report and a rate hike from the Bank of Japan, which led to a prolonged sell-off. These factors, along with political instability, have cast a shadow over the future of U.S. equities, coming at the end of what has largely been a robust earnings season. Below, we delve into some of the key themes that have emerged from the earnings reports of the past quarter. Profits Remain Resilient: The S&P 500 was anticipated to showcase an earnings growth of 10.8% as of Monday, based on data from FactSet. Should this forecasted growth rate hold true upon the completion of all 500 company reports, it would represent the index's most significant growth since the fourth quarter of 2021, which saw a substantial increase of 31.4%. Furthermore, companies have been exceeding earnings estimates at a rate of 78%, which is slightly higher than both the 5-year average of 77% and the 10-year average of 74%. However, the extent of these earnings beats, averaging at 3.5%, has fallen short of the norm, with an average of 8.6% over the past five years, hinting at underlying weaknesses. Revenue Growth Trails Earnings: Despite the robust earnings, the growth in revenue has not kept pace with profit margins, as both consumers and businesses have tightened their spending. The S&P 500 is projected to report a revenue growth of 5.2% for the quarter, which is beneath the 5-year average of 6.7%. Additionally, the proportion of companies that have reported revenues exceeding expectations is also below the 5-year average. The top lines have been constricted in recent quarters due to consumers grappling with inflation and being more mindful of their expenditures. However, not all companies have been affected equally. For instance, the burger chain Shake Shack (SHAK) reported its second consecutive quarter of double-digit revenue growth, while its competitor McDonald’s (MCD) experienced a decline in same-store sales during the second quarter. Analysts have attributed this divergence to the perception that the price difference between fast-food chains and "fast-casual" establishments such as Shake Shack, Chipotle (CMG), and Sweetgreen (SG) has diminished in recent years. Executives have also highlighted the strain that inflation, a slowing economy, and the depletion of pandemic-era savings have placed on lower-income Americans. Wall Street's Caution on Big Tech's AI Investments: Big Tech firms are investing heavily in artificial intelligence and show no signs of slowing down. Alphabet (GOOGL) and Microsoft (MSFT) have increased their capital expenditures by 91% and 55%, respectively, during the quarter, with a significant portion of this increase allocated to semiconductors and other hardware for AI-driven data centers. Both companies have indicated that they expect to continue this trend of increased spending in the coming year. The financial implications of Big Tech's aggressive pursuit of AI capabilities have rattled Wall Street in the past month. The Magnificent Seven stocks experienced some of their worst days on record during the fortnight when most of the group reported their earnings. The stocks are poised for another test when chipmaker Nvidia (NVDA) releases its earnings on August 28. The substantial investment in AI hardware by cloud providers is a positive sign for Nvidia's sales; however, expectations are high after four consecutive quarters of triple-digit revenue growth. Even with its recent decline, the stock could be adversely affected by indications of weakening demand or confirmation of reports suggesting that its next-generation Blackwell chips may be delayed due to a design flaw. The Financial Sector Eager for Rate Reductions: The financial sector has reported the third-largest increase in earnings of any sector this quarter, with profit growth of 17.6% from the same quarter of the previous year. All five sub-industries—Insurance, Capital Markets, Consumer Finance, Financial Services, and Banks—have reported earnings growth. High interest rates were initially beneficial for large banks, some of the sector's most significant players, as the interest they earned on loans increased. However, their deposit costs have since risen, eroding net interest income, a crucial financial metric for the industry. Now, with the Federal Reserve seemingly ready to cut interest rates from their highest levels in decades, the sector is approaching a turning point. Lower interest rates could once again boost banks' interest margins as their deposit costs decrease more rapidly than their income from fixed-rate loans. The sector could also benefit from an increase in loan demand and some relief for financially strained consumers, among whom credit card delinquency rates have recently reached a 12-year high.
