Shares of networking chips designer Marvell Technology (NASDAQ: MRVL) jumped 4.2% in the afternoon session after the US-Iran ceasefire eased fears of a major disruption to global tech supply chains.

Semiconductors are the backbone of the modern economy, and any threat to global shipping lanes like the Strait of Hormuz creates immediate “scarcity premiums.” With the strait reopened, the logistical path for raw materials and finished chips becomes far more predictable and cost-effective. The rally was also fueled by the continued “AI revolution,” which remains a primary growth driver regardless of oil price swings.

However, the cooling of energy-driven inflation provides a more favorable backdrop for the massive capital expenditures required to build new fabrication plants. As the “geopolitical discount” evaporates, chipmakers are seeing strong buy-side interest across both the logic and memory markets.

After the initial pop the shares cooled down to $138.90, up 4.7% from previous close.

Marvell Technology’s shares are extremely volatile and have had 35 moves greater than 5% over the last year. In that context, today’s move indicates the market considers this news meaningful but not something that would fundamentally change its perception of the business.

The previous big move we wrote about was 8 days ago when the stock gained 4% on the news that Barclays upgraded the company to an “Overweight” rating, citing a massive boom in AI infrastructure.

Analysts raised their price target to $150, predicting that Marvell’s optical networking business will grow by nearly 90% over the next two years. Investors are betting that Marvell’s specialized chips will be essential for high-speed internet ports, which are expected to double in demand by 2027.

Marvell Technology is up 55.4% since the beginning of the year, and at $138.90 per share, has set a new 52-week high. Investors who bought $1,000 worth of Marvell Technology’s shares 5 years ago would now be looking at an investment worth $2,978.
