Investing.com's Hot Stocks This Week

Investing.com – The Middle East conflict continues this week, with escalating tensions driving ongoing market volatility.

Although geopolitical uncertainty remains front and center, many semiconductor-related stocks have also experienced fluctuations for various reasons.

Here are the popular stocks on Investing.com this week:

SMCI

Super Micro Computer (NASDAQ:SMCI) stock plunged nearly 30% on Friday (as of 1:47 PM Eastern Time), after three individuals, including co-founder Liang Yixian, were accused of conspiring to smuggle advanced U.S. AI technology into China.

Following the news, Bernstein analyst Mark Newman stated, “Although Super Micro is not named as a defendant, this raises serious credibility issues that could impact the business.”

He added, “It’s one thing for rogue employees (allegedly) to commit fraud under your nose once, but re-hiring the same person (who also serves on the board), and that person (allegedly) doing even worse things later, is a completely different matter.”

Oil & Gas Stocks

The escalation of the Middle East conflict has led to attacks on both sides’ oil and natural gas facilities. Facilities related to Iran and the South Pars gas field were targeted, and Iran subsequently launched attacks on energy infrastructure in the region, including a large liquefied natural gas complex in Qatar.

The situation’s escalation caused oil and gas stocks to rise this week, with ExxonMobil (+4.7%), Chevron (+4.2%), Occidental Petroleum (+5.8%), BP (+5.5%), Shell (+3.1%), Devon Energy (+8.3%), ConocoPhillips (+6.2%), among others, recording gains.

Lumentum Holdings

Despite a more than 9% drop in Lumentum’s stock on Friday, the stock still gained over 10% in the past week, as investors reacted positively to comments from the Optical Fiber Communications Conference (OFC).

Rosenblatt analyst Mike Genovese commented in a report that, “Lumentum’s bullish demonstrations and other companies’ thoughtful presentations made Day 1 of OFC perform well.”

Meanwhile, Stifel analyst Ruben Roy wrote in a report, “At the Lumentum investor briefing at OFC 2026, management provided an updated long-term financial model, including achieving a quarterly revenue run rate of $2 billion within the next 18-24 months, with next-generation gross margins of 50.5% and operating margins of 40%.”

He added, “The company also emphasized that the total addressable market for optical AI will exceed $90 billion by 2030, representing about 40% compound annual growth from the $18 billion in the 2025 calendar year.” “We are optimistic about this event, as management’s message reaffirms the accelerating long-term growth drivers.”

Micron Technology

Micron’s performance was mixed this week. The stock started strong, reaching new highs. However, despite a solid earnings report on Wednesday that exceeded market expectations, the stock declined on Thursday and Friday.

Nevertheless, the stock still rose 1.6% over the past week.

In a post-earnings report, UBS analyst Timothy Arcuri raised Micron’s target price from $475 to $510, maintaining a buy rating.

He wrote, “Micron once again reported very strong results that beat expectations and raised guidance, though the stock pulled back slightly after hours. On one hand, we understand the view that the ‘upward momentum’ from the strong results and guidance has largely been priced in, with gross margins now guided above 80%.”

“On the other hand, Micron’s first signed agreement is for five years—far beyond our expectations—and customers only sign such agreements when they view memory as a strategic critical asset.”

Nvidia

Despite receiving positive feedback at GTC, Nvidia’s stock declined about 5.6% over the past week.

In a review report, Wedbush’s Dan Ives described the GTC keynote as a key “confidence boost” for tech investors, noting that “CEO Jensen Huang clearly stated that, despite market noise, the AI revolution is accelerating rather than slowing down.”

Ives emphasized that the updated revenue outlook was a major highlight, stating, “Jensen Huang significantly raised the bar, announcing that Nvidia now sees a $1 trillion+ revenue opportunity with Blackwell/Rubin.”
