Billionaire investor Leo KoGuan said he purchased a sizeable stake in Nvidia Corp. earlier this week, signaling broad confidence in the long-term prospects for artificial intelligence.
In a post on X, KoGuan said he acquired 1 million shares of Nvidia and indicated plans to increase his position. He wrote:
"I bought 1 million shares of NVDA last night; plan to buy more,"
"I am convinced AI is NOT a bubble, it is only the beginning,"
The purchase comes after Nvidia reported another very strong quarterly result last month, though its shares remained relatively muted in recent trading. Some sell-side analysts see opportunity in large-cap semiconductor names despite the lackluster near-term market reaction.
Analysts at Jefferies, led by Blayne Curtis, wrote that they view select large-cap names such as Nvidia and Broadcom as attractively positioned, arguing that valuations have become disconnected from fundamentals. In their note the team said:
"We still fundamentally believe both AVGO and NVDA are poised for breakouts as valuations are too depressed,"
They added that, even if recent earnings do not act as an immediate catalyst, their view remains that the two companies are among the clearest beneficiaries of AI adoption within their coverage. The analysts wrote:
"we continue to view AVGO and NVDA as the most certain AI winners in our space trading at basement bargain multiples."
KoGuan is a well-known investor who rose to prominence in part as one of the largest individual shareholders of Tesla. In recent years he has grown increasingly critical of Tesla and its chief executive, including opposing the company’s plan to provide a compensation package for the CEO that could have reached extraordinary levels.
Still, KoGuan said he remains substantially invested in Tesla alongside short-term U.S. government debt. He wrote that he is "still mostly in Tesla" and in Treasury bills, but he declined to quantify how much he has trimmed his Tesla stake over time.
He also argued that parts of Tesla’s business are undervalued by the market and could present future upside. On X he said:
"I do think Tesla’s energy, cybercap and Teslabot are NOT fully priced in,"
He suggested that daring investors could still buy Tesla for potential future returns, describing the company as "the leading embodied AI on earth." In November, KoGuan said he was "no longer all-in-Tesla" and had started accumulating 3-month Treasury bills instead.
Separately, automated stock-selection tools referenced in industry commentary evaluate Nvidia alongside thousands of other companies using a range of financial metrics. Those tools highlight fundamentals, momentum and valuation when identifying opportunities. The commentary noted that past picks from such models have included Super Micro Computer (+185%) and AppLovin (+157%).
Implications
- KoGuan’s large purchase underscores continued investor interest in AI-exposed semiconductor stocks.
- Market reaction to Nvidia’s strong quarter has been muted, prompting some analysts to view valuations as disconnected from fundamentals.
- KoGuan’s portfolio posture - concentrated positions in Tesla combined with allocations to Treasury bills - reflects a mix of equity conviction and liquidity management.
