According to CNA, oil prices climbed back above $100 a barrel and the 10-year Treasury yield hit a one-and-a-half-year high of 4.7% on July 23, 2026. The Dow, S&P 500 and Nasdaq fell 0.97%, 1.21% and 2.15% respectively. Tesla shares dropped 14.52% after a weaker-than-expected earnings report, wiping out roughly $200 billion in market value, while Intel beat estimates and rose 11% in after-hours trading.

How did oil prices and Treasury yields rise in tandem?

According to CNA (中央社), international oil prices climbed back above $100 a barrel on July 23, 2026, while the 10-year Treasury yield rose to a one-and-a-half-year high of 4.7%. The report attributed the moves to investor concern that escalating tension in the Middle East could disrupt tanker traffic through the Strait of Hormuz and the Red Sea, adding to what CNA described as an atmosphere of uncertainty in the market. SETN (三立新聞) carried an identical account, confirming both the $100-a-barrel threshold and the 4.7% yield level.

What were the day's losses across the three major US stock indexes?

CNA reported that on July 23, the Dow Jones Industrial Average fell 0.97%, the S&P 500 fell 1.21%, and the Nasdaq fell 2.15%. LTN (自由時報) reported the same three figures, framing the declines as a reaction to Middle East tension and the jump in oil prices. The Nasdaq's 2.15% drop was more than double the Dow's 0.97% decline, pointing to a heavier hit on technology-weighted trading that day.

Which major tech stocks fell, and by how much?

According to CNA, Alphabet, the parent of Google, fell 6.89% on July 23 even though the company's search, cloud and non-operating investment figures were described as strong; CNA said investors instead focused on a jump in the company's AI spending for the prior quarter. CNA also reported that Meta fell 3.36%, Amazon fell 4.57%, and Nvidia fell 1.56%, attributing the declines to investor worry over uncontrolled AI spending by large tech companies combined with the escalating Middle East conflict. Among the four names, Alphabet posted the steepest single-day decline at 6.89%, followed by Amazon at 4.57%, Meta at 3.36%, and Nvidia at 1.56%.

What was the impact of Tesla's earnings miss on its stock and market cap?

CNA reported that Tesla's prior-quarter earnings fell short of expectations, with revenue missing forecasts and cash flow turning negative; shares fell 14.52% following the release, and the company's market value dropped by about $200 billion in a single day. LTN's account, sourced from the same event, put the decline at "nearly 15%" with the same roughly $200 billion market-cap loss. SETN separately confirmed the "nearly 15%" share-price drop and the approximately $200 billion market-value loss, describing it within a broader picture of US stocks trading lower amid escalating Middle East conflict, renewed oil-price gains, and a slowdown in AI investment sentiment.

How did Intel's results compare, and did they move with the broader tech selloff?

According to CNA, Intel reported prior-quarter revenue of $16.1 billion, above the $14.4 billion analysts had estimated, and adjusted earnings per share of 42 cents, more than double the 21-cent consensus. CNA reported that Intel's shares still closed down 2.33% during the regular session but jumped 11% in after-hours trading following the results. LTN confirmed the same closing decline of 2.33% and the same 11% after-hours gain, describing Intel's performance as better than expected.

What this means

The same trading day produced two divergent outcomes among companies reporting earnings. Tesla's revenue miss and negative cash flow, as reported by CNA, LTN and SETN, drove a 14.52% share-price drop and roughly $200 billion in lost market value, aligning with the broader Nasdaq's steeper 2.15% decline compared with the Dow's 0.97%. Intel moved in the opposite direction: despite closing down 2.33% alongside the market-wide slide, its after-hours jump of 11% followed revenue and EPS figures that both beat estimates, according to CNA and LTN. Meanwhile, Alphabet's 6.89% drop, described by CNA as tied to investor concern over rising AI spending rather than weak underlying results, together with the declines in Meta, Amazon and Nvidia, suggests that AI-investment anxiety and the Middle East-driven jump in oil prices and Treasury yields were compounding pressures on tech shares that day, independent of each company's actual earnings performance.
