Retired finance professional. I can't see the future and neither can you; anyone who says different has something to sell. NOTHING I SAY IS INVESTMENT ADVICE.
The only time in history where the 30yr went from the 4%s to the 6%s within 6 months was June 1999.
73 trading days later, SPX was in a correction.
9 months later, SPX had its last ATH before falling into a years-long bear market.
To be clear, the 30yr is still under 6% now.
