AI infrastructure names delivered a week of strong gains, with memory, server and neocloud stocks rallying on results and guidance, while a high-profile consumer name went the other way. Nebius surged 34% on Wednesday and is up 39.1% heading into the close on Friday after second-quarter revenue jumped 454% year-over-year to $582.3 million, ahead of the $572.75 million analysts had expected. Super Micro Computer rose 19% on Wednesday and has gained 33.7% over the week after fourth-quarter results that missed on revenue but beat on earnings, driven by stronger gross margins, alongside guidance well above Wall Street estimates. SanDisk has climbed 24.5% over the week on renewed AI momentum and a bullish investor day held in New York. Reddit has gained 10.7% so far on Friday after S&P Dow Jones Indices confirmed the company will join the S&P 500 before the open on Aug. 18, replacing AvalonBay Communities, which is being acquired by Equity Residential. On Holding was a significant decliner this week, plunging 20.3% on Tuesday and looking set to end the week down around 15% after a second-quarter revenue miss and reduced guidance.
