NEW YORK, August 18, 2026, 11:20 EDT
The State Street SPDR S&P 500 ETF Trust NYSEARCA:SPY fell 0.6% on Tuesday. Though the decline was slight, certain sectors experienced sharper losses. Technology shares were hit hardest, as long-term borrowing costs climbed to their highest in 19 years.
The widening gap between broad market benchmarks and technology-centered indexes serves as an indicator for investors. Invesco QQQ Trust NASDAQ:QQQ fell 1.8%, lagging SPY by 1.15 percentage points. This disparity points to a selloff influenced by rate sensitivity, not a broad market retreat.
SPY remained within 1.5% of its highest level in the past 52 weeks. Broad sector makeup supported stability, with energy moving higher and investor interest rising in defensive sectors.

The yield on 30-year U.S. Treasuries rose to 5.327%, the highest level since 2007. Yields for 10-year notes advanced to 4.739%. Oil prices stayed above $90, reviving inflation fears after U.S.-Iran talks broke down.
| Macro pressure | Latest level | Why investors care |
|---|---|---|
| 10-year U.S. Treasury yield | 4.739% | Leads to higher discounting of future profits |
| 30-year U.S. Treasury yield | 5.327% | Hits a high last seen in 2007 |

Higher yields reduce the present value of anticipated future profits and raise the cost of financing growth in AI. “The yields are troubling people because it portends a tighter environment,” Bokeh Capital Partners investment chief Kim Forrest said. Reuters
The AI supply chain posted the sharpest losses. Shares of Micron Technology NASDAQ:MU dropped 7.5%. Broadcom NASDAQ:AVGO fell 3.5%, with Nvidia NASDAQ:NVDA losing 2.7%. Meta Platforms NASDAQ:META declined 3.4%.
| AI-linked share | Price | Day change | Market value |

| Broadcom NASDAQ:AVGO | $378.80 | -3.47% | $1.80 trillion |
| Nvidia NASDAQ:NVDA | $218.96 | -2.69% | $5.31 trillion |
| Meta Platforms NASDAQ:META | $549.66 | -3.39% | $1.40 trillion |
The figures show that a one-off rate shock can impact SPY in varied manners. Micron and Nvidia each post betas above 2.0, indicating their declines were steeper than the broader fund.
Wall Street analysts remain upbeat about Nvidia despite a decline in its shares on Tuesday. Among 37 analysts polled, 36 advise purchasing the stock. The average price target is $309.94, implying a possible 41.6% upside from present levels. These forecasts reflect expectations and are not guarantees.

SPY maintained exposure to all 11 sectors, with 504 stocks held as of late July. The fund’s forward price-to-earnings ratio stood at 21.61. This wide diversification resulted in a smaller drop on Tuesday, although valuation risk remains present.

|---|---|---|

| 52-week low | $629.28 | Price trades 22.01% above its low |

Attention turns to two significant developments. The Federal Reserve is scheduled to publish its minutes on Wednesday. Nvidia is also due to deliver results in the coming week, providing investors with fresh insight into AI spending trends and stable earnings.
Risks: A fresh spike in oil prices may push yields higher, adding strain to technology shares. Progress in diplomacy or a more dovish stance from the Federal Reserve could swiftly reverse these moves. Intraday prices remain open to adjustment.
