The S&P 500 was muted on Thursday as losses in tech heavyweights Microsoft and Nvidia countered earnings-led gains for Meta and Tesla, while investors parsed a slew of corporate earnings a day after the U.

Tesla stock rises on optimism over the electric-vehicle maker’s growth projections, Microsoft’s Azure growth misses estimates, Meta’s fourth-quarter profit handily tops forecasts, and UPS says it will be reducing volume with Amazon.

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

Nvidia shares' 9% recovery Tuesday was the second-best day in terms of market cap added for any company ever—but the company faced another selloff Wednesday.

Data center technology spending skyrocketed 34 percent in 2024, according to Synergy Research Group. It is soaring past a half a trillion dollars in the first month of 2025 as banks and technology vendors vie to build out massive AI compute.

Nvidia is launching its next-gen RTX 5090 and RTX 5080 GPUs today, but it’s also releasing an exciting update for existing RTX GPU owners. A new GPU driver (572.16) allows you to force DLSS 4 inside games or apps that don’t currently support it, providing improved image quality and even less VRAM usage in some cases.

Microsoft, MSFT, CEO Satya Nadella is expected to talk about DeepSeek, Stargate, Azure, Copilot, AI, GenAI and more on the tech vendor’s 2Q 2025 earnings call.

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.

In its own research, DeepSeek said it had “distilled” models from its R1 system based on other open-source systems. Unlike OpenAI’s closed systems, some models such as Meta’s Llama are open-source and freely available for use.

The superstar run for Nvidia’s stock the last few years has been astonishing. So was its tumble Monday, which caused $595 billion in wealth to vanish.
