MSCI Quarterly Review Adds Semiconductor Standout MPI, Raises TSMC Weight

MSCI indexes are key benchmarks for global institutional investors and passive funds, and changes to their constituents and weightings often drive substantial capital flows. MPI's promotion to the MSCI Global Standard Index reflects rising demand for semiconductor testing and the company's stronger industry position. It also underscores the semiconductor sector's continued dominance of Taiwan's equity market capitalization.

MSCI's latest quarterly review increased Taiwan's allocation and raised TSMC's weighting to 58.33%. Semiconductor test interface maker MPI was also added, while no memory-chip companies were included. The changes are scheduled to take effect after the market closes on May 29 and are estimated to attract about $2.3 billion in inflows, with passive funds set to rebalance their holdings according to the new weights.
