Retail investors bought a net $562 million of Nvidia stock on Monday, the largest single-day inflow in at least 10 years, VandaTrack said.

Shares of Nvidia ( NVDA -5.29%) were sinking Wednesday. The company's stock fell 6.2% as of 2:20 p.m. ET, but lost as much as 6.9% earlier in the day. The move comes as the S&P 500 ( ^GSPC -0.39%) and Nasdaq Composite ( ^IXIC -0.54%) lost 0.8% and 1.1%, respectively.

Since the start of 2023, Nvidia 's (NASDAQ: NVDA) stock has gained an astronomical 906% as of the time of writing. It's also right around its all-time high right now, but these two facts may scare some investors off. The common thought is, "Nvidia has risen so much already; how can it increase more?"

The GPU giant laid out a very smart approach to agentic AI earlier this month at CES, but it could do more to clarify its business model and its software strategy.

Then there is the hype question. Since Chat GPT set off the AI gold rush in late 2022, Nvidia has been the ultimate “picks and shovel” play. But like investment in the early days of the internet, the AI boom has so far been based more on the belief that it will change everything than hard evidence that it can generate returns.

Nvidia stock is losing ground today amid multiple bearish catalysts related to the DeepSeek R1 artificial intelligence ( AI) model that was released last week. For starters, investors are weighing the possibility that DeepSeek's new AI signals a significantly weaker demand outlook for Nvidia's advanced AI processors than previously expected.

DeepSeek just shook up the artificial intelligence (AI) world in the biggest way since OpenAI launched ChatGPT in late 2022. The Chinese company's new R1 large language model (LLM) reportedly matches or beats OpenAI's o1 model on some benchmarks.

Timothy Arcuri, an analyst at UBS, said: “The sheer magnitude of the moves in stocks like Nvidia, Broadcom and Marvell [on Monday] strike us as overdone and may generally look like a buying opportunity in hindsight once the dust settles.”
