The Vanguard S&P 500 ETF (VOO) has declined for seven straight trading days, reaching its lowest level since June 11. This pullback comes despite a backdrop of generally positive macroeconomic and corporate developments, raising questions about the sustainability of the broader equity rally.
Positive Catalysts Fail to Stem the Slide
Several factors that typically support risk assets have emerged recently. A preliminary US-Iran agreement has pushed crude oil prices lower, with Brent falling to $70 per barrel and West Texas Intermediate (WTI) to $69. Lower energy costs are widely seen as beneficial for both consumer and producer inflation. Indeed, the headline Personal Consumption Expenditures (PCE) price index rose to 4.1% in May from 3.8%, but the decline in commodity prices has fueled expectations that inflation may moderate further, reducing the likelihood of additional Federal Reserve rate hikes.
Corporate earnings momentum also remains robust. Micron Technology reported quarterly revenue growth of over 300%, and management signaled continued strength. According to FactSet, consensus estimates for second-quarter S&P 500 earnings growth stand at 22%. Historically, actual results have exceeded initial projections—first-quarter estimates of 12% were surpassed by the reported 28%, the highest in years. The index’s forward price-to-earnings ratio of 22 is above its five-year average of 19, but stronger revenue growth may justify the premium.
Concentration Risk in AI and Memory Stocks
Despite these tailwinds, the market’s advance has been heavily concentrated in a narrow set of names tied to artificial intelligence and memory chips. Sandisk has surged 855% year-to-date, while Micron, Western Digital, and Seagate have each gained over 263%. Other top performers include Intel, Marvell, Dell, Corning, Applied Materials, and AMD—all suppliers to hyperscale cloud operators such as Microsoft, Meta Platforms, and Google.
The risk is that any slowdown in hyperscaler capital expenditure could trigger a sharp reversal in these high-flying stocks. Notably, Microsoft has already fallen 36% from its July 2025 peak, Amazon is down 18% from its year-to-date high, and Google has dropped over 15%. A broader unwind in AI-related names could weigh heavily on the S&P 500 and ETFs like VOO.
Technical Indicators Point Lower
From a chart perspective, VOO has broken below its 25-day exponential moving average (EMA). A double-top pattern has formed, a classic bearish reversal signal. Additionally, both the Relative Strength Index (RSI) and the Moving Average Convergence Divergence (MACD) are exhibiting bearish divergence—prices are making lower highs while momentum indicators decline.
These technical signals suggest the ETF could continue to drift lower in the near term. The next key support level is the 100-day moving average near $655. A move to that zone would represent a further decline from current levels and could set the stage for a potential bounce ahead of the upcoming earnings season.
For context on broader market dynamics, the Dow Jones faces four key headwinds including bond yields and technical signals, while the dollar index has dropped 10% since 2025, testing the currency's trust premium. Meanwhile, the gold targets a fourth consecutive weekly gain amid shifting macro forces.
