$Micro 2-Year Yield - main 2210(2YYmain)$As long as the peak Fed target rate stays at an expected 5%, there's plenty of room for the 2yr yield to go higher as it tends to overshoot the peak Fed rate.
ARKK has returned almost 250% since 2015 while BRK.B 120%. With higher returns, we would expect greater volatility and higher risk. I would say that if you want to be ahead of the curve, ARKK is the one to go for. If you want to be behind the curve, then BRK.B.
