Marvell Technology, Inc. (NASDAQ:MRVL) stock rose more than 3% in Thursday’s premarket session as investors returned to semiconductor stocks amid improving risk appetite and growing confidence that the AI infrastructure buildout remains in its early stages.

The advance came alongside strength across equity futures and semiconductor names. The Nasdaq gained 1.18% in premarket trading, while the Russell 2000 rose 1.34%. The iShares PHLX SOX Semiconductor Sector Index Fund climbed nearly 3%, highlighting broad-based demand for chip stocks.

AI Infrastructure Theme Remains a Key Catalyst

Investor enthusiasm for AI-related infrastructure spending continued to support the sector after NVIDIA Corporation (NASDAQ:NVDA) CEO Jensen Huang said the recent global technology selloff created a buying opportunity because the AI buildout remains in its early stages.

Speaking to Bloomberg, Huang said investors should be “very happy” because the pullback allows them to “buy at a discount.” He added that AI will become global infrastructure “just like the internet was infrastructure for the world,” reinforcing expectations for continued spending on chips, networking equipment, and data centers.

Those comments are particularly relevant for Marvell, whose networking, connectivity, and data-center products are widely viewed as critical infrastructure supporting AI workloads and data movement.

S&P 500 Inclusion Adds Another Tailwind

Marvell also continues to benefit from its upcoming addition to the benchmark S&P 500 Index.

The inclusion is expected to drive demand from index funds and other passive investment vehicles that track the benchmark. Such additions often increase institutional ownership and trading volumes as funds adjust their portfolios to reflect the index change.

Technical Picture Remains Bullish

Marvell remains in a strong long-term uptrend. The stock trades well above its major moving averages, including the 20-day simple moving average of $223.67 and the 200-day moving average of $106.46.

The 20-day moving average remains above the 50-day moving average, while the 50-day moving average remains above the 200-day moving average, preserving a bullish golden-cross structure established in October 2025.

Momentum indicators also remain constructive. The MACD sits above its signal line and continues to show positive momentum, suggesting buyers remain in control despite the stock’s extended run.

The next major resistance level is the June 52-week high of $324.20, while support is located near the 20-day moving average at $223.67.
