correlations come and go. Nothing remains 100% consistent in the market all the time. Generally Bonds are risk-off investments.
I think in this case with Growth being “attached” to Yields is a symptom of high valuations and record low rates. If rates start to rise investors risk:reward ratio for holding very expensive, speculative assets diminishes as they can theoretically get a better return on risk-free investments (assuming Treasury Bonds are risk-free, which I don’t think that’s true but it has been the case so far in American history)
