The previous day's loss in U.S. markets was concentrated in technology and chip stocks; Brent held at $91.83 and the 10-year U.S. Treasury yield at 4.70% as the Kospi fell 5.2% in the August 19 Asian session.

This is not yet a collapse happening across all markets at once. But pressure from rates and oil is putting valuation first, then market participation, on test for technology stocks priced for long-term growth expectations.

Bora Özkent's (@boraozkent) framework emphasizing the effect of rate pressure on stocks combines with the chip concentration highlighted in Bloomberg Television and Yahoo Finance coverage. Kanal Finans's (@tuncsatiroglu) view that the gold and silver trend remains intact is a reminder that risk appetite is not moving as one.

Key takeaways

  • The decline in U.S. indexes came with a technology tilt; Nasdaq weakness makes continued chip selling in Asia more important.
  • Nasdaq 100 ETF QQQ at $717.76, semiconductor ETF SMH at $569.84 and Meta ($META) at $543.60 all finished August 18 below their previous active recovery lines.
  • Brent at $91.83 is above the $90 resistance and the 10-year Treasury yield at 4.70% is above its directional line; the August 19 9:00 p.m. TRT FOMC minutes are the next near-term catalyst.
  • Bitcoin around $64,236, Ethereum $1,911 and XRP $1.00; crypto is still not providing independent confirmation of risk appetite.

What happened?

  • According to the Associated Press's August 18 close, the S&P 500 fell to 7,691.76, the Dow Jones to 53,343.40 and the Nasdaq Composite to 26,289.71; the Russell 2000 was at 3,017.89.
  • In its August 19 Asia update, the Associated Press reported that the Kospi fell 5.2%, Samsung 6.9% and SK Hynix 7.9%; Brent rose to $91.83, WTI to $84.88 and the 10-year Treasury yield held at 4.70%.
  • Completed August 18 IEX bars showed Nasdaq 100 ETF QQQ at $717.76, semiconductor ETF SMH at $569.84, IWM, the ETF that tracks small U.S. companies, at $300.24, software-company ETF IGV at $101.99, GLD at $398.53 and SLV at $57.435.
  • Bloomberg Television and Yahoo Finance coverage highlighted that selling was concentrated especially in chips and that Treasury yields were testing expensive technology valuations; CNBC Television discussed the oil-rate-technology transmission.
  • Kpler data cited by the AP showed Hormuz transits down 19.5% to 95; this data and official statements show that uncertainty around energy flows continues, not that a diplomatic outcome has been completed.

Market levels

Global risk and oil

  • Brent at $91.83 is above the first resistance line at $90; $87 is support and $95 the main risk threshold. A sustained move below $90 would ease oil pressure on technology, while a move above $95 would increase the risk.
  • The 10-year U.S. Treasury yield is at 4.70%; 4.65% is support, 4.70% the directional line and 4.85% the main resistance threshold. Holding above 4.70% increases the funding cost of high valuations.

US indices

  • The S&P 500 at 7,691.76 is below the 7,750 support and reclaim line; 7,800 is the pivot and 7,850 the next resistance. The high-level structure cannot be considered repaired until 7,750 is reclaimed.
  • QQQ at $717.76 is below the $725 support zone; $734.56 is first resistance and $740 the next threshold. Technology leadership cannot be considered reconfirmed until $725 is reclaimed.

Themes and ETFs

  • Semiconductor ETF SMH at $569.84 is below the $585 support zone; $600 is main resistance. Until $585 is reclaimed, there is no short-term momentum repair in the AI-investment theme.
  • U.S. small-company ETF IWM at $300.24; the support zone is $302-$303, the pivot $305 and resistance $310. Below $303, market breadth cannot be said to be offsetting the technology selloff.
  • Software ETF IGV at $101.99 is below the $103.70 support zone and just above the $101 risk area; $106.30 is first resistance. Rate sensitivity persists in software until $103.70 is reclaimed.
  • Meta at $543.60 is below the $580 support/risk line; $590 is resistance. Company-specific weakness cannot be considered over until $580 and then $590 are reclaimed.

Crypto and precious metals

  • Bitcoin around $64,236; $62,000 support, $67,000 conditional confirmation and $58,000 the next risk area. Until $67,000 is cleared, the move is not confirmation of broad risk appetite.
  • Ethereum around $1,911; $1,850 support and $1,950 resistance. XRP around $1.00; $0.92 support and $1.07 confirmation. Both remain range-bound.
  • Gold ETF GLD at $398.53 is just below the $400 support zone; Kanal Finans's cited spot-gold confirmation condition of $4,425 is not on the same scale as the GLD price.
  • Silver ETF SLV at $57.435 is below the $58 support zone; unless the cited spot-silver confirmation condition of $66 is cleared, the metals move is not broad-based confirmation.

Red flags

  • If Brent stays above $90 while the 10-year Treasury yield exceeds 4.70%, valuation pressure on technology stocks will grow; above 4.85% would indicate a more severe risk regime.
  • If QQQ stays below $725, SMH below $585, IWM below $302 or IGV below $101, market participation weakens even without the selloff spreading beyond technology.
  • If the August 19 FOMC minutes point to a tighter rate tone, the correction in chip and software stocks could deepen; no directional assumption should be made before the result is released.
  • If GLD cannot hold $400, SLV $58 or Bitcoin $62,000, a clearer split emerges between defensive demand and broad risk appetite.

Calendar

  • Wednesday, August 19, 9:00 p.m. TRT: Minutes from the July 28-29 FOMC meeting will be released. The rate path, technology valuations and the Treasury market make this the day's main catalyst.

My analysis

My base case is not a full flight from risk, but a selective correction in long-term growth stocks driven by rates and financing costs. The concentration of the August 18 U.S. loss in technology and the deepening chip selloff in Asia on August 19 fit this reading; but with QQQ and SMH having lost support, it is too early to call it healthy rotation.

My intraday decision filter is clear: Brent holding above $90 and the 10-year yield exceeding 4.70% keep the pressure alive; QQQ reclaiming $725 and SMH reclaiming $585 would test the prior breakdown. If the August 19 9:00 p.m. TRT FOMC minutes show a tighter tone, technology valuations will come under renewed pressure; a softer tone alone is not a trend reversal.
