ACMR is trading 10.4% up today at $115.38 after being shifted into several Russell growth indices, a move expected to attract significant institutional interest and passive fund flows.

  • The index reclassification highlights the company's growth trajectory, potentially increasing liquidity and demand from fund managers tracking these benchmarks.
  • The surge is further supported by a broader rally in the semiconductor sector, with major indices gaining over 1% as investors rotate back into high-growth chip-equipment stocks.
