Western Digital Corporation (NASDAQ: WDC) has emerged as one of the standout technology stories of 2025. The company’s stock has appreciated by approximately 195% year-to-date, recently trading around $175 per share. This impressive performance is set to receive another significant boost as the company officially joins the Nasdaq-100 Index prior to the market open on Monday, December 22, 2025.
This inclusion is more than just a badge of honor or a vanity metric. It validates the company's strategic decision to separate its Flash memory business in February 2025. That move transformed Western Digital into a focused provider of hard disk drive (HDD) infrastructure.
