A toxic brew of rising 10-year Treasury yields and increasing inflation jitters plagued growth strategies, including ARKK, earlier this year, but for now, at least, those fears are ebbing. Thing is, growth stocks have longer duration cash flows, making them sensitive to interest rate fluctuations so when Treasury yields nearly doubled in the first quarter, ARKK languished. That benefits a slew of exchange traded funds, including the famed ARK Innovation ETF (NYSEArca: ARKK).
