Analysis
A Shift in Market Leadership
The recent momentum unwind in the S&P 500 is a significant event, with the Goldman high-beta momentum basket falling 24% month-to-date, its worst stretch since April 2009. The Morgan Stanley tech momentum index posted a record -35% 17-day rate of change. This shift in market leadership is a change from the narrow band of high-beta and semiconductor names that carried 2026 to the broad market underneath.
Why Alphabet's Earnings Matter
Alphabet's upcoming earnings are critical for market direction. The company's capex guidance and earnings quality will determine if the AI-driven momentum trade stabilizes or if the correction deepens. This will be a key swing factor for tech and semiconductors.
Rebalancing Risk
In the current rotation, it is recommended to rebalance risk, avoid chasing semiconductors lower, and do not short the broad market. Maintain tight stops on crowded names and let earnings confirm the next move.
