The dominance of TSMC, Samsung, and SK Hynix has created a lopsided market, with these three firms now representing nearly one-third of the MSCI Asia Pacific ex-Japan Index. This concentration mirrors the 'Magnificent Seven' phenomenon in the United States, yet it has unfolded with greater intensity in Asia. Portfolio managers are now caught in a cycle of forced selling; as these stocks continue to climb, they exceed internal risk mandates, compelling funds to divest even when company fundamentals remain strong.

This structural distortion makes it increasingly difficult for active managers to beat benchmarks that are effectively tethered to only a few names. At the country level, the disparity is stark: while the broader regional index has risen 27% year-to-date, excluding the tech-heavy markets of Korea and Taiwan, the index is actually down 4%. Consequently, capital is fleeing active management in favor of passive vehicles at an unprecedented rate, with $510 billion flowing into passive funds over the last five years, contrasted by $269 billion in outflows from active managers. To navigate this, stock pickers are shifting down the supply chain, targeting mid-sized firms like ASMPT and Grand Process Technology to avoid the risks associated with the industry’s top-heavy giants.
