The overnight fade did not reverse once cash opened. As flagged in this morning's analysis, E-mini futures had already slipped toward 7,732 after Monday's 7,745.06 close, with oil holding 85 dollars and the 10-year climbing toward 4.75 percent. Cash made that worse. The S&P 500 opened at 7,700.04 and closed at 7,691.76, breaking Monday's 7,744.88 low and the 7,728 level this morning named as invalidation of the weekly-gain tone. Semiconductors did the damage. This is the evening scorecard of what played out, not an instruction.

The Close: Cap-Weighted Pain, Mixed Breadth

The S&P 500 fell 53.30 points, or 0.69 percent, to 7,691.76, opening at 7,700.04 with a 7,688.63-7,713.95 range. Yahoo Finance timestamped the close at 4:20 p.m. Eastern; Reuters printed a preliminary 7,692.10. The Nasdaq Composite dropped 1.33 percent to 26,289.71. The Dow lost 0.22 percent to 53,343.40. The Russell 2000 fell 1.30 percent to 3,017.89. The VIX rose 4.3 percent to 15.84. Breadth was mixed, not a wipeout: Barron's noted roughly 300 S&P members higher and 18 of 30 Dow names up. Energy and healthcare offset some of the chip hit. The tape was a semiconductor and mega-cap problem.

Key Takeaways: The Close
  • S&P 500 -0.69% to 7,691.76, open 7,700.04, low 7,688.63
  • Nasdaq -1.33% to 26,289.71; Dow -0.22% to 53,343.40
  • VIX 15.84 (+4.3%); Russell 2000 -1.30% to 3,017.89
  • This morning's 7,728 invalidation and Monday's 7,744.88 low both broke

Story of the Day: Chips Unwound Monday's Bid

Monday evening's note had Sandisk up about 8.9 percent and Micron 4.1 percent. That bid reversed. Sandisk fell about 9 percent, Seagate about 9.2 percent and Micron about 6.9 percent after Micron's nearly 18 percent five-session run, per Reuters. Western Digital dropped about 7.4 percent, Intel 6.6 percent, Nvidia 2.4 percent and AMD 4.4 percent. Meta lost about 4.5 percent. The other weight was the long end. The 30-year yield tagged 5.337 percent, a 19-year high, then eased toward 5.29 percent. The US 10-year, near 4.75 percent this morning, faded to about 4.71 percent (CNBC 4.708 percent at 3:38 p.m. Eastern). Energy offset some of it: Exxon rose about 2.6 percent and Targa about 7.1 percent. Eli Lilly, Johnson & Johnson and AbbVie all gained more than 3 percent.

A Home Depot associate in an orange apron helps a customer choose plumbing parts in a store aisle on Tuesday August 18 2026, the session Home Depot beat second-quarter sales at 47.9 billion dollars and reaffirmed guidance even as July US housing starts crashed 12.4 percent to a 1.239 million annual rate

Home Depot Beat, Housing Starts Did Not

Home Depot did what this morning previewed. Sales rose 5.7 percent to 47.9 billion dollars versus about 47.27 billion expected. Adjusted earnings were 4.92 dollars a share against the 4.73 consensus. Comparable sales rose 1.7 percent. Management reaffirmed full-year guidance and pointed to repair demand in what executives called a frozen housing market. The stock finished roughly flat, down 0.12 percent on Yahoo after an early lift. The Census print was much worse. July starts fell 12.4 percent to a 1.239 million annual rate, versus about 1.36 million expected and June's revised 1.415 million. Single-family starts fell 9.9 percent to 808,000. Permits rose 5.0 percent to 1.443 million. Pending home sales slipped to 71.2 from 72.5. Reddit joined the S&P 500 as scheduled, replacing AvalonBay.

Key Takeaways: Housing and HD
  • Home Depot sales $47.9B, adjusted EPS $4.92 vs ~$4.73; guidance held
  • HD finished roughly flat (-0.12%) after an early lift
  • July starts 1.239M, -12.4% vs ~1.36M expected; single-family 808k
  • Reddit joined the S&P today, replacing AvalonBay as mapped

Crypto Check: Bitcoin Holds $64,000; Gold and Oil Fade

Digital assets ignored the equity fade, as they did Monday. Bitcoin is near 64,600 dollars, holding the 64,000 reclaim this morning mapped. TradingView printed 64,591 and Yahoo 64,615 around 20:14 UTC, with a 64,004-64,945 range. Ether is near 1,913 dollars, up from this morning's 1,898. Thursday's KAITO unlock remains the week's largest scheduled supply. Gold did not hold. Spot gold fell to about 4,333 dollars (Trading Economics 4,332.40, Investing.com 4,333.73), breaking the 4,400 shelf and Friday's 4,376 support. West Texas Intermediate faded from this morning's 85.30 dollars toward 84.25 on Yahoo's September contract (range 83.77-85.06). The 85-dollar hold did not survive the cash session. Bullish trigger for Bitcoin is a hold above 64,000 dollars. Bearish trigger: a slip through 62,800. For gold, traders are watching 4,315 as the next reference zone after the 4,340 break. These are observations, not instructions.

Key Takeaways: Crypto, Gold, Oil
  • Bitcoin ~$64,600, holding the $64,000 reclaim (low ~$64,004)
  • Ether ~$1,913, firmer than this morning's ~$1,898
  • Gold ~$4,333, breaking $4,400 and Friday's $4,376 support
  • WTI ~$84.25, faded from this morning's ~$85.30 hold

After-Hours and Overnight Watch

Tuesday after-hours was quiet. No mega-cap reports were due after the close. Three things frame Wednesday: Lowe's and Target before the open, the next read on housing-linked and discretionary retail after Home Depot's beat and the starts crash; EIA inventories; and the week's pivot, FOMC minutes at 18:00 UTC. Analog Devices also prints. Walmart reports Thursday. Hormuz headlines remain the overnight wildcard. Bullish trigger for the S&P: a reclaim of 7,728, then Monday's 7,745.06. Bearish trigger: a slide through today's 7,688.63 low. The docket sits in this week's week-ahead note.

Key Takeaways: What's Next
  • No major Tuesday after-hours earnings; the large-cap calendar is quiet
  • Lowe's and Target before Wednesday's open; Analog Devices also due
  • EIA inventories and FOMC minutes 18:00 UTC on Wednesday
  • S&P bullish trigger: reclaim 7,728; bearish: a slide through 7,688.63
