MTS funds showed differentiation rather than a retreat, and northbound funds had a strong willingness to flow in, although the net outflow of broad - based ETFs accelerated [5][11]. - Institutions took a left - hand approach, while MTS and northbound funds served as accelerators for the incremental funds since the beginning of the year. Northbound funds became an incremental force for short - term market activity [9]. - The performance of broad - based indexes was differentiated. Large - cap and dividend indexes declined, while technology stocks and micro - cap stocks performed well [10][13]. 3.
