Markets popped mid‑March

On March 16 U.S. benchmarks posted their strongest session since the Iran war began, with the Dow closing at 46,946.41, the S&P 500 at 6,699.38 and the Nasdaq at 22,374.18. (cnbc.com)) NVIDIA’s GTC developer conference opened March 16 and runs through March 19, with CEO Jensen Huang’s keynote scheduled for 11 a.m. PT and organizers expecting roughly 39,000 attendees from around the world. (fool.com)) In the keynote Huang put the addressable market for NVIDIA’s AI chips at “at least $1 trillion” through 2027, a figure Reuters reported as central to the company’s investor messaging. (msn.com)) NVIDIA used GTC to roll out the Vera Rubin platform and multiple new chip/system announcements aimed at large‑scale and “agentic” AI workloads, according to the company’s live blog and technology coverage. (blogs.nvidia.com)) Despite the ambitious roadmap, market commentary flagged NVDA shares as relatively range‑bound after the presentations, with some analysts calling the immediate price reaction muted versus the scale of the announcements. (investors.com)) Oil moves drove the other side of the tape: front‑month crude pulled back below $100 on March 16, a drop traders said eased near‑term inflation and rate‑cut concerns and helped risk appetite that day. (investopedia.com)) Those gains proved fragile — on March 17 Brent climbed to about $103.48 a barrel and U.S. WTI to roughly $96.64 after renewed Iranian attacks on the UAE, a roughly 3% one‑day rise that rekindled supply‑risk worries. (money.usnews.com)) Institutional risk teams sharpened the warning: Goldman Sachs told clients a severe, prolonged oil‑supply shock from the Middle East conflict could drive the S&P 500 down toward roughly 5,400 in a downside scenario.
