Overview

• In the supplied posts for 2026-06-29 to 2026-07-06 UTC, activity was concentrated on Jun 29–30.
• The week focused on semiconductor-heavy exposure and short-term tactical trades. A Jun 29 portfolio risk report showed concentrated positions in SMH (32.38%), AMAT (14.22%), and ASML (13.57%), with AI/semi exposure at 68.71% and cash/cash-like at 34.96%.
• Trading posts showed realized gains in AMZNUSDT, AMATUSDT, and MUUSDT, while ETH was discussed as a breakout attempt within a broader range context.

Key Themes

• Concentration risk management: Repeated emphasis on using support/resistance discipline rather than chasing strength, especially given heavy AI/semi exposure.
• Semiconductor bias remained strong: AMAT was highlighted positively; some storage exposure was partially taken for profit; MU was bought with 5x leverage and later closed profitably.
• New name added: COHR was bought, with a follow-up note that its 1W chart had reached a support zone.
• ETH setup: One ETH chart post called the structure “textbook” but still range-bound; later posts treated ETH as a breakout with a near-term target around 1700, and an ideal-case chart toward ~1850.
• Enterprise software watch: A market note flagged ServiceNow + Accenture’s AI risk/cybersecurity partnership as worth tracking, but not as an immediate guidance-changing event.
