How This Could Play Out
First assessed Oct 31
Resolved

Status quo
LIKELYTech valuations remain compressed as earnings disappointments persist without resolution, keeping equity risk premiums elevated and rotation flows into defensive sectors and fixed income steady.
Worsens
POSSIBLEBroader equity selloff accelerates as tech weakness triggers margin calls and forced liquidations across leveraged portfolios, dragging cyclical and financial stocks lower and widening credit spreads.
