The 10-year yield and the $SPY are moving in opposite directions right now—and it's a strong inverse relationship. When yields drop, stocks rally. When yields climb, stocks get hit.

This isn't always the case. Sometimes bonds and stocks move together. Sometimes they ignore each other entirely. But right now? They're locked in a tight dance, and the correlation is deeply negative.

What does that tell us? The market is treating falling yields as good news—probably because it signals either cooling inflation or expectations of Fed cuts. Lower borrowing costs, higher valuations, classic playbook.

But here's the thing: correlations like this don't last forever. They shift. They break. And when they do, it catches people off guard.

If you're trading on the assumption that yields down = stocks up, just remember—markets don't owe you consistency. They owe you nothing.
