QUAD WITCHING DAY
Quad Witching Expiration — Heightened Volatility Expected
September 18 is the quarterly Quad Witching day, where stock options, index options, single-stock futures, and index futures all expire simultaneously. Expect above-average volume and intraday swings, particularly in the final hour of trading. Institutional rebalancing may create unusual price action across major indices and large-cap names.
2
AI RALLY EXTENDS
AI-Related Stocks Extend Rally in Premarket
US AI-related stocks are extending yesterday’s strong gains in premarket trading. Semiconductor and large-cap tech names are leading the charge as NQ futures surge +1.14%. Investor sentiment remains bullish on AI infrastructure spending and upcoming next-generation chip announcements expected at major tech events.
3
TREASURY YIELDS
10Y Treasury Yield Near 5% as Oil Prices Surge
Treasury yields are pressing higher as WTI crude trades near $101.95/barrel, adding inflationary pressure. The 10Y yield approaching 5% raises concerns over the Fed’s rate path. Markets are closely watching this week’s Fed communications for guidance on whether rate hikes remain on the table for Q4 2026.

EARNINGS WRAP
Major Q2 2026 Earnings Reports Wrapping Up This Week
The earnings season for Q2 2026 is drawing to a close with several remaining large-cap reports this week including Netflix (NFLX) and Alphabet (GOOG). Broader S&P 500 earnings growth has broadly outpaced expectations, supporting the index’s recent run to all-time highs above 7,600.
5
CONSUMER SENTIMENT
University of Michigan Consumer Sentiment Due Today
The University of Michigan Consumer Sentiment final reading for September is due today, serving as a key macro data point to close out the trading week. The preliminary reading came in below expectations; any downside surprise could dampen the bullish premarket tone and weigh on consumer discretionary stocks.
🎯 Today’s Trading Strategy
Quad Witching caution: With all four major expiration classes converging today, expect abnormal volume spikes — particularly in the last hour. Avoid chasing breakouts near the close; let institutional rebalancing play out.
Tech momentum: NQ futures +1.14% suggests tech remains the leadership sector. Consider holding positions in AI/semiconductor names through the open, but watch for profit-taking as prices approach recent highs.
Yield watch: If the 10Y approaches 5.0% decisively, growth and rate-sensitive sectors (tech, REITs, utilities) could face pressure. Keep stop-losses in place.
Fear & Greed at 30: Contrarian signal — extreme fear readings historically precede recoveries. Accumulating quality names on dips may be rewarded over a 2–4 week horizon.
