Dow and Small Caps Lead; Nasdaq-100 Proxy Slips
In the October 20 session, ETF proxies pointed to a split tape: the Dow and Russell 2000 proxies rose about 1.0% and 1.7% while the Nasdaq-100 proxy edged down 0.1% and the S&P 500 proxy added 0.3%. Company news was earnings-driven, with Netflix results arriving after the close and Boeing securing a long-delayed certification. Note that this brief was assembled with degraded data: one news feed was unavailable and some ticker data was excluded.

Netflix beats on earnings, shares fall on guidance
CNBC reported that Netflix posted a third-quarter earnings beat but that shares declined on advertising and revenue guidance. Ahead of the report, options pricing implied a roughly 9% post-earnings move, the highest since the company's third-quarter 2022 report.
Boeing receives FAA approval for 737 Max 10
Boeing won FAA certification for the 737 Max 10, the largest model in the family, after years of delays; the aircraft had been set to enter service in 2020 before increased scrutiny and safety issues extended the process. Transportation Secretary Sean Duffy said the certification process should be faster, according to CNBC.
September housing indicators fall more than expected
CNBC reported that September data showed sales, construction and sentiment in the US housing market all declining by more than anticipated. The packet does not include the underlying figures or the releasing agencies.
Data-center power constraints surface in company guidance and commentary
Australian operator NextDC's shares fell about 40% after it cut earnings guidance, citing power supply delays at its Melbourne facility amid local community and stakeholder opposition, CNBC reported. Separately, BlackRock CEO Larry Fink said opposition to data centers would push inflation higher — a stated view, not an established outcome.
