Buying more of an investment that has underperformed or selling it after it has outperformed may cause the MWR to be higher than the TWR.

Buying more of an investment that has performed well or selling when it has underperformed may cause the MWR to be lower than the TWR.
Jonah bought more units at a higher price in June, resulting in a weaker performance on his personal return (MWR) than the investment (TWR).
Buy and hold strategies that eliminate cash flows during the measurement period make the TWR and MWR equal.
