Hello, This etf looks interesting: https://www.ishares.com/us/products/251614/ishares-msci-usa-momentum-factor-etf I'm used to ETFs that keep their holdings very steady (Like the S&P 500). This one seems to have some sort of computation going on that identifies momentum stocks and then places them in/out of the portfolio. If we are a shareholder of the ETF, do we constantly get hit with capital gains taxes? If the underlying portfolio churns a lot, I'm guessing any profits on the securities exiting the ETF get assigned to us as tax. But I'm not sure. I'm curious if anyone has an idea of how a factor ETF like this goes about selecting/updating its stocks, and what the tax effects are on the shareholder.
