Abstract generation in progress

Nasdaq has unveiled the outcomes of its annual index reconstitution affecting the Nasdaq-100 Index (NDX). The reshuffling took effect in late December 2025, marking the exchange’s regular portfolio adjustment cycle. Six new corporations gained entry to the prestigious index, while the same number exited—a typical pattern reflecting evolving market dynamics and company performance metrics.

New Companies Joining the Index Reconstitution Framework

The six organizations added to the Nasdaq-100 represent a mix of innovation-driven sectors. Alnylam Pharmaceuticals, Inc. (ALNY) brings biotech expertise in RNA interference therapeutics. Ferrovial SE (FER), a European infrastructure specialist, expands the index’s international exposure. Insmed Inc. (INSM) contributes further to the pharmaceutical segment, focusing on rare infectious diseases. Monolithic Power Systems, Inc. (MPWR) strengthens the semiconductor and power management subsector. Meanwhile, storage technology leaders Seagate Technology Holdings plc (STX) and Western Digital Corp. (WDC) reinforce the index’s computing infrastructure representation.

Six Companies Exiting Following the Annual Index Reconstitution

The departing six members reflected shifting competitive positions. Biogen Inc. (BIIB), once a biotech heavyweight, saw its weighting decline. CDW Corporation (CDW), an IT solutions distributor, was removed alongside GlobalFoundries Inc. (GFS), a semiconductor manufacturer. Lululemon Athletica Inc. (LULU), the athletic apparel retailer, no longer meets the index’s composition criteria. ON Semiconductor Corporation (ON) and The Trade Desk, Inc. (TTD) similarly exited—representing shifts in the semiconductor and digital advertising sectors respectively.

Understanding the Index Reconstitution Significance

This annual index reconstitution process reflects Nasdaq’s commitment to maintaining the Nasdaq-100 as a dynamic representation of the market’s most significant non-financial companies. By systematically adjusting membership, the index captures emerging opportunities while acknowledging evolved corporate positioning. Such portfolio reshuffling ensures the index remains a relevant benchmark for investors tracking innovation-focused market segments.
