In some cases, I might not have much choice, because the need to transact may be driven by the mandate I have been given. But in that case, a discussion should at least be had with the provider of the mandate highlighting the higher transaction costs and the implications that has for the portfolio.
Or maybe I need to transact because of redemption flows out of my fund. In that situation, I may need to think about holding a higher liquidity buffer than I did in the past.
