Stock Market Today, July 21, 2026: ISRG Sinks 14% as Guidance Disappoints; Netflix Extends Slide Ahead of Alphabet and Tesla Earnings

Wall Street kicked off a high-stakes earnings week on a cautious note Monday, July 21, 2026, as investors positioned ahead of Alphabet (GOOGL) and Tesla (TSLA) reports due after the close on Tuesday. Lagging healthcare and tech stocks — pounded by lingering fallout from last week's earnings releases — kept the major indexes in the red. The S&P 500 declined, the Nasdaq fell more sharply on semiconductor and medtech pressure, while the Dow edged modestly lower.

Market Performance: July 21, 2026

All four major U.S. equity benchmarks closed in the red on Monday:

• S&P 500 (^GSPC): Fell approximately 0.6%–1.0%, with the prior Friday close at 7,457.69. The VIX climbed to 18.77, up more than 12% on the day, signaling heightened market anxiety.
• Nasdaq Composite (^IXIC): Dropped approximately 1.5% to around 28,593 in composite terms, weighed heavily by semiconductor, EDA software, and medtech stocks.
• Dow Jones Industrial Average (^DJI): Slipped modestly, trending lower from its prior Friday close of 52,146.42 on broad risk-off sentiment.
• Russell 2000 (^RUT): Declined about 0.42% to around 2,962, with small caps underperforming as investors rotated away from riskier assets ahead of megacap tech earnings.

In the bond market, the 10-year Treasury yield held near 4.55% following the prior Friday's close. WTI crude oil traded near $79/barrel amid ongoing U.S.-Iran tensions in the Middle East. Bitcoin (BTC-USD) held near $65,437 after gaining roughly 2.4% over the weekend.

Top Stories: Earnings Reactions and Big Tech on Deck

Intuitive Surgical (ISRG) Drops 14% Despite Earnings Beat

Intuitive Surgical (NASDAQ: ISRG) was one of the S&P 500's worst performers on Monday, extending the sharp decline that began after the company reported Q2 2026 results on July 16. The stock fell approximately 14.15% to $345.42, adding to an earlier double-digit drop from the post-earnings reaction.

The Q2 results themselves were strong: revenue came in at $2.89 billion, up 18.5% year over year, beating the $2.82 billion consensus. Adjusted EPS of $2.80 exceeded estimates of $2.51 by nearly 12%. Da Vinci procedures grew 15% year over year, and Ion procedures climbed 36%. The company installed 468 da Vinci surgical systems in the quarter, up from 395 a year earlier.

Investors sold the stock after management guided for full-year 2026 da Vinci procedure growth of 13.5%–15.5%, with performance expected around the midpoint of 14.5%. Concerns emerged about U.S. procedure volumes linked to potential reductions in ACA health insurance coverage, and a Class II recall of certain da Vinci surgical components added further pressure. Intuitive CEO Dave Rosa stated: "We are pleased with company performance this quarter, which reflects the strength of our portfolio." The company ended Q2 with $8.63 billion in cash and investments.

Netflix (NFLX) Extends Post-Earnings Slide

Netflix (NASDAQ: NFLX) continued to slide Monday, dropping about 7.26% to $68.95. The streaming giant reported Q2 results on Thursday, July 17: revenue of $12.56 billion (up 13.4% year over year), net income of $3.4 billion, and EPS of $0.80 — essentially in line with Wall Street's $12.59 billion revenue estimate and $0.79 EPS consensus.

The driver of the sell-off was guidance: Netflix issued weaker-than-expected Q3 revenue projections. For the full year, the company narrowed its 2026 revenue range to $51.0–$51.4 billion, and maintained its 31.5% operating margin target. The ads business remains on track to deliver approximately $3 billion in revenue for 2026. Netflix also noted fewer World Cup-linked subscription sign-up events as a headwind compared with prior live event periods.

EDA Software Stocks Slide: Cadence and Synopsys Under Pressure

Electronic design automation (EDA) companies Cadence Design Systems (NASDAQ: CDNS) and Synopsys (NASDAQ: SNPS) fell sharply Monday — CDNS was down about 9.47% to $330.11 and SNPS dropped 7.85% to $384.28. The pressure stems from growing market concern that Chinese AI startup Moonshot AI's Kimi K3 chip-design model could disrupt the EDA industry, potentially reducing demand for premium Western design tools. This narrative has weighed on EDA software stocks throughout July 2026. Cadence is scheduled to report Q2 2026 earnings on July 27.

KeyCorp and Capital One Report Q2 2026 Earnings

Regional bank KeyCorp (NYSE: KEY) reported second-quarter 2026 results before the open on Monday, with analyst consensus expecting approximately $0.42 in adjusted EPS. KeyCorp had beaten estimates in Q1 2026, posting $0.44 vs. the $0.41 consensus. The banking sector has broadly benefited from the elevated rate environment in 2026, with the Fed holding its target rate at 3.50%–3.75%.

Capital One Financial (NYSE: COF) released its Q2 2026 earnings at approximately 4:05 p.m. Eastern Time, with a conference call at 5:00 p.m. ET. The company, which completed its transformative acquisition of Discover Financial and Brex, was expected to post roughly $4.69 in adjusted EPS for the quarter. Capital One holds $682.9 billion in total assets and operates as one of the largest credit card issuers in the United States. JP Morgan maintained its Overweight rating on COF on July 13, raising its price target from $215 to $245.

Federal Reserve Closed Board Meeting and FOMC Countdown

The Federal Reserve's Board of Governors held a closed meeting Monday morning at 9:00 a.m. ET. The stated matter: "Periodic Briefing and Discussion on Financial Markets, Institutions, and Infrastructure." This is a routine briefing and does not relate to imminent policy decisions. The next scheduled FOMC meeting is July 28–29, 2026. Following the weak June nonfarm payrolls report (+57,000, well below the 115,000 consensus), CME FedWatch implied approximately 78.5% odds of no rate hike at the July meeting. PCE inflation for May 2026 remained at 4.1% year over year.

Biggest Movers: Monday, July 21, 2026

• Intuitive Surgical (ISRG): −14.15% to $345.42 — Q2 beat overshadowed by disappointing full-year procedure growth guidance and ACA coverage concerns.
• Cadence Design Systems (CDNS): −9.47% to $330.11 — AI chip-design disruption fears from Chinese startup Moonshot AI's Kimi K3 model.
• Synopsys (SNPS): −7.85% to $384.28 — Same AI disruption narrative hit EDA software peers.
• Netflix (NFLX): −7.26% to $68.95 — Extended post-earnings slide on Q3 revenue guidance miss.
• Axon Enterprise (AXON): −5.81% to $510.28 — Sympathy selling in high-multiple growth names.
• Travelers Companies (TRV): +9.22% to $368.98 — One of the S&P 500's top performers; strong Q2 2026 earnings beat.
• Seagate Technology (STX): +5.66% to $787.66 — Positive momentum in storage stocks on robust data center demand.

Q2 Earnings Season Context: Strong Beats, Tough Guidance Bar

Q2 2026 earnings season is tracking strong fundamentals. S&P 500 companies are on pace for year-over-year earnings growth above 20% for the second consecutive quarter — FactSet's consensus stands at approximately 23.6% growth. The technology sector is expected to lead with 65.5% year-over-year earnings growth, driven by AI infrastructure investment. Hyperscaler capex from the top five — Microsoft, Alphabet, Amazon, Meta, and Oracle — is projected to grow 79% year over year to $644 billion in 2026.

Yet the pattern this season is clear: guidance matters more than beats. Netflix and Intuitive Surgical both exceeded Q2 estimates but were punished for underwhelming forward outlooks. The S&P 500 forward P/E sits near 20.1x — down from 22.2x at year-end 2025 — suggesting valuation has moderated, but the bar for positive reactions remains high at current prices.

Tomorrow's Market Calendar: Alphabet and Tesla Take Center Stage

• Alphabet (GOOGL/GOOG) — Reports Q2 2026 after close, conference call at 1:30 p.m. PT / 4:30 p.m. ET. Consensus: revenue $116.8B (+21.1% YoY), Google Cloud $22.2B (+63.3% YoY), EPS ~$2.87. Key metrics: Cloud growth trajectory, Gemini AI monetization, and 2027 capex guidance (Evercore projects up to $300B).
• Tesla (TSLA) — Reports Q2 2026 after close. The company delivered 480,126 vehicles (+25% YoY) in Q2, well above the ~406,600 consensus. Focus: margins, FSD commercialization, Robotaxi timeline, and updated CapEx guidance (recently raised to $25B+).
• AT&T (T) — Reports Q2 2026 before the open Tuesday; consensus EPS ~$0.57.
• FOMC Quiet Period — The Fed enters its blackout period before the July 28–29 FOMC policy meeting. No Fed speeches are expected.
• Existing Home Sales (Wednesday, July 23) — June housing data from the National Association of Realtors. The 30-year fixed mortgage rate stood at 6.43% as of early July.

Conclusion: Alphabet and Tesla Hold the Key to This Week's Tape

Monday's session captured the defining theme of this earnings season: strong results are expected and priced in. Intuitive Surgical and Netflix both beat estimates, and both stocks fell hard on guidance. The S&P 500, Nasdaq, and Russell 2000 all declined as investors lightened positions ahead of Tuesday's critical Alphabet and Tesla reports.

The Alphabet report is the pivotal event for the AI infrastructure thesis: if Google Cloud sustains 60%+ growth and management raises 2027 capex, it would signal that hyperscaler AI spending is accelerating — a major positive for semiconductors, data centers, and the broader tech sector. A disappointment, particularly on Cloud growth or search advertising, could extend the sector's July losses. Tesla's margin trajectory and any concrete Robotaxi timeline will similarly set the tone for the EV and autonomous driving space. With the FOMC just eight days away and inflation still above 4%, the next 48 hours carry outsized significance for where markets end this week.
