BlackRock Shifts €13B of ETFs to Full Replication Amid AI Concentration

BlackRock has converted €13 billion of European ETFs from optimized sampling to full physical replication as soaring AI and semiconductor stocks pushed holdings toward UCITS concentration limits. The move allows the funds to use higher issuer limits available to fully replicating ETFs, improving benchmark tracking while remaining compliant with regulations. The change reflects growing pressure from concentrated mega-cap technology names such as Micron and ASML and comes as European regulators consider revising concentration rules for benchmark-tracking funds.
