Memory, optical, and AI-construction stocks dive as embattled SaaS stocks rebound
On March 30, 2026, the stock market witnessed a significant shift as memory, optical, and AI-construction stocks faced a steep decline, while software-as-a-service (SaaS) stocks showed signs of recovery. This article explores the factors contributing to these market movements and highlights key players in each sector.
Memory Stocks Plummet
Memory stocks experienced a notable sell-off, continuing a trend that began the previous week. The decline was triggered by new developments regarding a potentially more memory-efficient AI algorithm from Google Research. Major companies such as Western Digital, Micron, Seagate Technology Holdings, and the popular retail choice Sandisk saw their stock prices tumble.
Industry publication Wccftech reported that several memory chip prices have experienced a significant drop across multiple U.S. retailers. Despite a positive initiation from JPMorgan analysts who rated Seagate as “overweight,” indicating a buy recommendation due to the potential for significant upside, the company could not escape the broader downturn affecting the data center trade.
Optical Stocks Face Pressure
Optical stocks, which had recently been high-flyers, also took a hit. Companies including Applied Optoelectronics, Corning, Lumentum, Coherent, and Ciena Corp. faced selling pressure. This downturn was exacerbated by reports of Samsung’s entry into the silicon photonics market, raising concerns among investors.
AI-Construction Stocks Decline
AI construction stocks such as Emcor, Vertiv Holdings, and Sterling Infrastructure also saw their values decrease. The overall sentiment in the market suggested a cautious approach towards sectors that had previously enjoyed high valuations.
SaaS Stocks Show Resilience
In contrast to the declines in memory, optical, and AI-construction stocks, traders appeared to be returning to the more stable and profitable SaaS and cybersecurity sectors. Companies like ServiceNow, Zscaler, CrowdStrike, Salesforce, and Atlassian reported solid gains during midday trading, indicating a shift in investor sentiment towards more reliable revenue streams.
Market Overview
While the S&P 500 index fell on the day, it managed to post a winning week amid optimism surrounding ceasefire talks between the U.S. and Iran. This broader context highlights the volatility and complexity of current market conditions.
Intel’s Remarkable Performance
Amidst the turmoil, Intel has emerged as a standout performer. The chip giant’s shares surged, making it the best performer in the S&P 500 for the month, with a remarkable gain of nearly 43% as of late March. Over an eight-day period, Intel’s stock rose by almost 50%, marking its best streak in the last 30 years.
Investors have responded positively to Intel’s recent announcements, including partnerships with Tesla’s CEO Elon Musk on the Terafab project and collaborations with Alphabet to develop custom chips for Google Cloud’s AI infrastructure. The increasing demand for computing capacity and AI-related chips has raised hopes that Intel can resolve long-standing issues within its contract chipmaking business, known as a foundry.
Furthermore, the U.S. government’s investment in Intel, acquiring a nearly 10% stake for approximately $8.9 billion, has significantly increased in value, now worth around $27 billion. This backing has bolstered investor confidence in the company’s future prospects.
Challenges for Palantir
Palantir Technologies has faced a challenging environment, with its stock sliding as much as 6% before stabilizing. This decline has been attributed to growing concerns about competition from emerging AI models, particularly from Anthropic, which recently released a new product focused on multi-agent orchestration.
Despite the sell-off, Palantir retains powerful supporters, including former President Trump, who recently praised the company’s capabilities on social media. However, the negative sentiment surrounding AI’s potential to disrupt traditional software companies has impacted Palantir’s stock performance.
Market analysts have noted that while Anthropic’s growth is impressive, it may not necessarily come at the expense of Palantir’s business, as the latter continues to expand in both commercial and government sectors.
China’s Electric Vehicle Exports Surge
In a related development, China has seen a remarkable increase in electric vehicle (EV) exports. The China Passenger Car Association (CPCA) reported that the country exported more than twice as many electric vehicles and plug-in hybrids in the first quarter of 2026 compared to the same period last year. This surge in new energy vehicle exports, up 124% year-over-year, has been driven by major players like BYD and Chery, as well as Tesla’s significant contributions to overseas shipments.
As the automotive industry in China continues to recover slowly, companies like Nio are ramping up their export efforts, aiming to deliver thousands of EVs overseas and establish a presence in multiple countries.
Conclusion
The recent fluctuations in the stock market highlight the ongoing challenges and opportunities faced by various sectors. While memory, optical, and AI-construction stocks are currently under pressure, SaaS and cybersecurity stocks show resilience. Companies like Intel are demonstrating remarkable performance amidst the volatility, while emerging players in the AI space continue to reshape the landscape.
