This inclusion highlights the company's significant market position and its sustained expansion within the chip and automation industries. The transition is expected to trigger increased institutional demand as index-tracking exchange-traded funds (ETFs) begin mandatory share acquisitions.

The inclusion comes amid a period of significant momentum for the semiconductor industry, with TER shares recently hitting record highs following optimistic earnings forecasts.
