Market notes

Leadership has rotated, and the tape is confirming it

Momentum score change by thematic cluster, healthcare and IT services gaining, semiconductors losing
Momentum score change by thematic cluster, morning session of 24 August 2026. Proprietary cluster ranking.

Three weeks ago I asked: rotation or distribution? The market answered. Rotation — and it has a macro engine behind it.

Since the June peak, the semiconductor complex has shed roughly $1 trillion in market value. In the same window, healthcare broke out: biotech cleared a ceiling that had capped every rally since 2021. Our cluster momentum work says the move is still live.
