Cross-Asset Read

The pro-cyclical unwind defined the session across equities, rates, and specialty exposures.
The 3M leadership cluster sits in EWZ, COPX, XLE, ETHA, GDX, and IBIT, and Thursday extended that trend in EWZ while COPX and GDX broke lower against standing gains; fixed income added the same direction, with TLT and LQD extending 3M declines of 3.7% and 2.4%.
Volatility expands in TLT and MUB, while compression holds in COPX, GDX, ACWV, DIA, EMB, and HYG; the cross-asset regime is selective, with pressure in duration and cyclicals rather than broad liquidation.
