Semtech, Allegro MicroSystems, and Kulicke and Soffa Shares Skyrocket, What You Need To Know

Barchart·04/17/2026 15:32:36

What Happened?

A number of stocks jumped in the afternoon session as 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.

The stock market overreacts to news, and big price drops can present good opportunities to buy high-quality stocks.

Zooming In On Semtech (SMTC)

Semtech’s shares are extremely volatile and have had 40 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 1 day ago when the stock gained 6.9% on the news that industry bellwether Taiwan Semiconductor Manufacturing Co. (TSMC) reported a substantial 58% jump in quarterly profit and forecasted strong future sales, fueled by booming demand for artificial intelligence (AI). 

As the world's largest contract chipmaker and a key supplier for tech giants like Apple and Nvidia, TSMC's performance is often seen as a barometer for the entire industry. The company posted a record net profit of $18.1 billion for the first quarter, a 58.3% increase from the previous year. 

Looking ahead, TSMC attributed its optimistic outlook to the continued surge in demand for advanced computing chips required for AI applications. This robust report signals underlying strength and vigorous demand across the global chip market, lifting sentiment for other semiconductor companies.

Semtech is up 43.1% since the beginning of the year, and at $107.71 per share, has set a new 52-week high. Investors who bought $1,000 worth of Semtech’s shares 5 years ago would now be looking at an investment worth $1,561.

ALSO WORTH WATCHING: Nvidia’s Quiet Partner. Nvidia’s chips cost a hundred grand. The connectors that make them work cost even more. One company makes them all.

Every AI server needs specialized infrastructure the chip companies don’t make. High-speed cables. Power connectors. Thermal sensors. This 90-year-old company built a monopoly on it. The AI boom just started. This stock is still flying under the radar. Claim The Stock Ticker Here for FREE.
