Broad-market ETF proxies closed lower on Oct. 23, with the Dow proxy (DIA) down 1.24% and the S&P 500 proxy (SPY) down 0.52%, while the Nasdaq-100 proxy (QQQ) finished essentially flat at -0.01%. Reporting during the week focused on strains in AI-related financing, a 10-year Treasury yield back near 5%, and Brent crude at a six-month high. Note that these are ETF proxies, not the underlying indices, and parts of today's data feed were incomplete.

Strains surface in AI buildout financing
CNBC reported stock slumps, pulled IPOs and rising credit default swap spreads among companies tied to the AI buildout, including Solidigm withdrawing its IPO, ahead of hyperscaler earnings. MarketWatch separately reported that record inflows into a leveraged semiconductor ETF preceded losses this month as questions about AI investment returns resurfaced.
10-year Treasury yield back near 5%
CNBC reported the 10-year Treasury yield was just below 5% on Friday after declining during the week, attributing the move to demand for government bonds amid tech selling. A separate CNBC piece said some investors are beginning to see opportunities in a bond market that has been weak this year.
Brent crude reaches six-month high
CNBC reported Brent crude topped $116 a barrel, a six-month high, amid rising Middle East tensions, and noted President Trump accused Iran of attempting to manipulate the oil market. A related report said the Iran conflict has redirected global energy flows, including a Qatari agreement to buy U.S. natural gas.
France: unrest lifts yields; Moody's leaves rating unchanged
CNBC reported French unrest pushed the country's bond yields to a 24-year high as investors weigh budget and growth risks ahead of further protests. Moody's left France's credit rating at Aa3, according to a separate CNBC report.
