Yes, that is exactly the tricky part. Yields and equities do not maintain a simple inverse relationship at all times.
When yields are rising on the back of structural growth, both can move higher simultaneously. However, the relationship becomes more complex when you decompose what is actually driving yields.
Nominal bond yields reflect three components: growth expectations, inflation expectations, and term premium. If the move is growth-driven, equities can continue to perform. The concern arises when rising yields are driven by term premium or persistent inflation expectations rather than growth. In that scenario, the discount rate applied to future earnings rises without a corresponding improvement in the earnings outlook, creating a genuine headwind for equity valuations regardless of near-term earnings momentum. This is why understanding what is behind a yield move matters as much as the move itself.
strong growth and earnings can still push stocks up even if this breaks to the upside
