During the earnings call, Jensen Huang jokingly referred to the "dinner effect": having dinner with me = stock price doubling.

Nvidia CEO Jensen Huang's every word and action is becoming a "weathervane" for the capital market.

During the latest quarterly earnings call, Jensen Huang quipped, "One of the most interesting things in the past year was seeing where I ate dinner and who I dined with—and the next day, that person's stock price doubled." One of the best US stock trading strategies for 2026 might be keeping an eye on who he dines with. He had previously joked that he "spends all day helping others sell stocks."

This is not entirely a joke. Over the past few months, Jensen Huang has frequently appeared in Asia, and his public statements have repeatedly acted as catalysts for the stock prices of related companies. From urging SK Hynix to "produce more" memory chips in Seoul and calling market corrections "discounted buying opportunities," to stating during Computex that Marvell is "destined to become a trillion-dollar company," his remarks have often had a rapid impact on the stock prices of related companies.

A Bloomberg article previously warned that as Jensen Huang's personal influence continues to grow, his optimistic statements could further amplify investors' bullish sentiment. Given that the AI industry chain is highly dependent on anticipated trading, the "Jensen Huang effect" is becoming a variable that cannot be ignored in the market.

The "dinner party effect" is no joke: your stance determines the market.

Jensen Huang's influence has spread from Nvidia's own fundamentals to the entire AI and semiconductor industry chain.

In June of this year, Huang Renxun stated at an event in Seoul that market corrections present "discounted buying opportunities," and investors "should be very happy." That same day, the iShares Semiconductor ETF (SOXX) surged nearly 6%, with chip stocks such as Nvidia, AMD, and Broadcom rebounding collectively, and the semiconductor sector quickly recovering its previous losses. The day before, the Nasdaq index had plummeted 4%, wiping out over $1 trillion in market capitalization from technology stocks.

During the same trip, Huang also publicly urged SK Hynix to "produce more" memory chips. At the time, the stock had risen by about 200% year-to-date, and his statement further reinforced the market's optimistic expectations for AI storage demand. Subsequently, he also publicly recommended Qualcomm, stating bluntly, "Buy their stock," and Qualcomm's stock price immediately rose by about 2% in after-hours trading.

During Computex, the "Huang effect" was even more pronounced. He publicly stated that Marvell was "destined to become a trillion-dollar company," and Marvell's stock price subsequently surged by more than 32% in a single day, marking its largest single-day increase in three years, with its market capitalization increasing overnight from approximately $192 billion to over $254 billion.

From memory chips to chip design, and then to the entire AI supply chain, Huang Renxun's words are increasingly translating into real-time market trends. As the personal influence of a CEO begins to become a significant variable affecting stock prices, the question of whether the "dinner party effect" truly reflects the prosperity of the AI industry or is merely an overblown signal of market sentiment is becoming a problem investors must confront.
