September 21, 2026 in numbers
Marvell Technology Inc. (ISIN US5738741041, Nasdaq: MRVL) finished the regular session at USD 252.47 after adding USD 8.22, or 3.37 percent, from the previous Nasdaq close, placing the close between the day’s intraday low and high on the same venue. Per exchange data, the move left the shares further above recent support levels while still below their 52-week high reported for this listing earlier in the year.

The session’s strength followed Marvell’s announcement that it is showcasing industry-first 2nm optical interconnect demonstrations for AI data center infrastructure at the European Conference on Optical Communication 2026 in Málaga, Spain, a detail the company highlighted in a release carried by Las Vegas Sun. The demonstrations include next-generation optical interconnect solutions designed to scale bandwidth for hyperscale AI deployments, a theme echoed in coverage by Invezz, which noted that the stock gained about 2 percent intraday as investors reacted to the optics news.
