Cross-Asset Read

Selective de-risking framed the session, with pressure concentrated in Asia and semiconductors while defensives and duration drew bids. The 3M leadership stack centers on IBB at +24.1%, XLV at +17.0%, EWT at +13.8%, and VLUE at +13.0%; Tuesday extended XLV and IBB, broke with EWT, and left fixed income leadership in JNK at +1.6%, HYG at +1.5%, and EMB at +1.3% largely unchanged by the day’s moves. Volatility is compressed in COPX, DIA, EFA, AGG, BNDX, EMB, ETHA, GDX, and IBB, and XLE is overbought; the cross-asset regime is selective, with drawdowns concentrated in EWY at -8.13%, EWT at -3.16%, and SMH at -4.09% rather than spread across the field.
