[Hong Jang-won’s Bull & Bear] This stock jumped as semiconductors fell
- What to look for
- Separate observed co-movement in AI shares, Treasuries and property shares from causal interpretations, and examine how financing structures change exposure to lower investment.

A Treasury decline need not fully reach mortgage rates
Split a hypothetical mortgage rate into a comparison Treasury yield and the remaining spread. A 0.3-percentage-point Treasury decline plus a 0.2-point spread increase leaves a net 0.1-point decline. Separately record lending standards and affordability to distinguish a property-share rally from housing demand.
