📰 Today’s Top 5 Stories

1 TOP 1

Dow Snaps Five-Month Winning Streak

The Dow lost 0.86% on the session and finished September down sharply, ending a five-month run of gains. The S&P 500 posted a small monthly decline while the Nasdaq held up better, highlighting rotation toward AI-linked growth.

2 TOP 2

Apple Leads Megacap Losses

Apple fell about 2.7% late in the session, the biggest single drag on the price-weighted Dow. Quarter-end rebalancing out of mega-cap winners added to the pressure.

3 TOP 3

PCE Inflation Lands, Yields Stay Elevated

The Fed’s preferred inflation gauge came in without a major upside surprise, but the 10-year yield still edged up to 5.29%. A methodology change in weighting is seen by some as a potential tailwind for future readings.

4 TOP 4

White House Doubles Down on AI Data Centers

After meeting top AI executives, the President reaffirmed support for data-center build-outs and stressed the importance of the AI race, while downplaying fears that AI will displace jobs. Talk of a new AI-powered government services portal added to the theme.

5 TOP 5

Micron Results & Brokerage Platform Expansion

Micron reported after the bell, a key read on AI HBM memory demand. Separately, a leading retail brokerage unveiled a wave of new offerings — AI agent trading, 24/7 trading, prediction markets and expanded crypto — signaling the ongoing convergence of fintech and digital assets.

🎯 Today’s Trading Strategy

New quarter, fresh flows: Q4 inflows on 10/1 often reverse quarter-end selling — watch whether mega-caps bounce.

Follow Micron’s reaction: A strong memory print can lift the whole semiconductor complex; a miss would test the Nasdaq’s relative strength.

Respect 5.3% on the 10Y: A break above keeps pressure on small caps and rate-sensitive sectors.

🔮 Market Outlook & Risk Factors

Bull Case: Nasdaq resilience, policy support for AI infrastructure and fresh Q4 inflows → dips in AI leaders keep getting bought; VIX near 16 shows no panic.

Bear Case: 10Y at 5.29% and oil back above $90 → valuation pressure, weak breadth (Russell lagging) and a soft September for blue chips.
