Based on my observations over the past few months (fluctuations in returns), these two assets have shown a certain degree of ups and downs. Sometimes COIN rises more, sometimes HOOD rises more. (Didn't pay attention during drops) In other words, since it's impossible to determine who will rise more during specific time periods, this kind of back-and-forth might present some degree of switching arbitrage opportunities, with returns exceeding those of a portfolio or the highest single asset return.
