Wall Street Brief (July 21): US equities edged lower on Monday, with major tech names diverging; parts of the AI supply chain saw localized recovery, while Chinese ADRs strengthened. Market sentiment did not deteriorate further, but a cautious tone persisted.

Summary: US stocks slipped modestly on Monday, with the S&P 500 down 0.19%, the Nasdaq down 0.05%, the Dow Jones Industrial Average down 0.59%, and the Russell 2000 down 0.67%. Among the four major indices, the Nasdaq nearly closed flat, while the Dow and Russell 2000 underperformed. Selling pressure shifted away from tech stocks toward traditional large-caps and small-caps. The VIX fell to 18.65, down 0.64% on the day—indicating sentiment did not worsen further, though caution remained. Trump announced 50% additional tariffs on certain Canadian goods, and escalating Middle East shipping risks kept US Treasury yields and oil prices elevated. Sector-wise, energy held up relatively well, while healthcare and rate-sensitive segments came under pressure. Chinese ADRs rallied broadly, led by Alibaba. Across asset classes, the 10-year Treasury yield rose 1.26%, gold fell 0.24%, crude oil gained 0.79%, Bitcoin rose 0.72%, and the dollar index climbed 0.20%.

I. Major Events

1. Trump announced 50% additional tariffs on certain Canadian goods

On July 20, Trump announced 50% additional tariffs on certain Canadian goods, citing discriminatory practices by Canada against the US in sectors including automobiles, alcoholic beverages, and cheese. Although the new tariff rates do not take effect immediately, the move has brought North American trade tensions back into market focus and prompted investors to reassess upside risks to imported inflation and supply chain costs. This development directly supported sustained strength in the US dollar and Treasury yields, while weighing on small-cap and cyclical sectors that are more sensitive to interest rates.

2. US airstrikes on Iran continue, raising energy shipping risks

On July 20, the US military stated that airstrikes on Iran had entered their tenth consecutive night. On the same day, Yemen’s Houthi rebels announced plans to blockade Saudi Arabia’s key Red Sea shipping lanes. Together, these developments heightened market concerns over the Strait of Hormuz and Red Sea—two critical energy transit routes—and reinforced the view that high oil prices may persist longer than previously expected. As a result, crude oil and long-end yields remained firm, while equity markets continued to compress valuations in rate-sensitive segments.

II. Major Trends

On Monday, the four major indices posted only modest declines overall, but their internal structure has already shifted. The Nasdaq was nearly flat, while the Dow Jones and Russell 2000 saw larger losses, indicating that the market is no longer indiscriminately selling growth stocks but instead initially pressuring traditional large-cap and small-cap stocks under a higher interest rate environment.

From a medium-term perspective, QQQ has gained 7.74% over the past three months, still outperforming DIA’s 5.15% and IWM’s 5.64%, showing that tech growth maintains its medium-term advantage. The current phase resembles a digestion period following previous crowded trades rather than a clear reversal of the broader trend.

In the short term, QQQ declined 3.70% over two weeks, remaining the weakest among major indices; XMAG dropped 3.16%, and growth-focused SPYG fell 1.79%, all notably underperforming value-oriented SPYV, which declined just 0.53%. Meanwhile, the two-week losses for DIA and IWM have continued to widen, suggesting that selling pressure is no longer confined to AI-related names but is spreading across a broader segment of the index structure.

III. Market Sentiment

Market sentiment showed slight improvement on Monday. The VIX retreated to 18.65, down 0.64% for the day; the CNN Fear & Greed Index rose to 38 from the prior reading of 37, though it remains in cautious territory. The CBOE total put/call ratio stood at 0.81, with the index options put/call at 1.04 and the equity options put/call at 0.72. Volatility did not continue rising, and speculative sentiment in equities has not deteriorated into panic levels. However, demand for downside protection on indices remains elevated, reflecting persistent market wariness toward high oil prices and high interest rates.

IV. Market Scan

1. Index ETFs

The four major indices continued to diverge on Monday. The Nasdaq-100 (QQQ) held up best, the S&P 500 (SPY) was in the middle, while the Dow Jones (DIA) and Russell 2000 (IWM) were weaker. This structure suggests the market is not currently executing a broad-based exit from mega-cap tech but is instead compressing sectors more sensitive to rates and with weaker cyclical leverage first.

2. Sector Performance

Energy (XLE) rose 0.45%, making it the strongest sector, while healthcare (XLV) fell 1.14%, the weakest. There was no broad-based sector rally during the session—instead, positioning resembled selective defensive moves amid sustained high oil prices. Within sub-sectors, copper miners (COPX) gained 0.70%, the strongest performer; meanwhile, solar (TAN) dropped 2.24%, biotech (XBI) fell 2.15%, and homebuilders (XHB) declined 2.01%. The high-rate environment continues to weigh on rate-sensitive segments. At the same time, several individual stocks within optical communications and AI storage rebounded, indicating that although the AI trade has not resumed broad strength, localized recovery is already underway.

3. The Magnificent Seven Tech Stocks

The Magnificent Seven tech stocks remained mixed. Microsoft gained 2.15%, the strongest performer, reflecting more stable demand for software and cloud infrastructure; Tesla dropped 2.96%, the weakest, followed by Apple, which fell 2.14%, showing greater pressure on consumer hardware and high-beta names. Overall, mega-cap tech failed to stage a coordinated rally, with capital rotating among AI infrastructure, platforms, and consumer electronics.

4. Chinese ADRs

Chinese ADRs rallied significantly as a group. Alibaba surged 4.67%, leading the pack, followed by Futu (+3.34%), JD.com (+3.31%), Baidu (+2.40%), KWEB (+2.35%), PDD Holdings (+2.27%), NetEase (+2.22%), and Bilibili (+2.05%). This rebound was driven both by anticipation around Alibaba’s new AI model announcement and by broader recovery in Chinese assets following recent pullbacks, making Chinese ADRs one of the few concentrated pockets of strength on the day.

5. Cryptocurrencies

Bitcoin rose 0.72%, posting a modest rebound, while high-beta cryptocurrency-related stocks rallied even faster. MARA jumped 9.17%, CRCL gained 8.25%, and MSTR climbed 3.13%, indicating that risk appetite has partially recovered within the crypto ecosystem. This rebound remains largely tactical for now; whether it can broaden further will depend on Bitcoin’s ability to sustain its upward momentum.
