Tuesday's U.S. stock trading volume$Meta Platforms (META.US)$The No. 1 index closed down 1.64%, with trading volume totaling $31.541 billion.
Sources revealed that Meta Platforms (META.O)'s expanded $25 billion stock offering attracted subscription demand roughly five times the number of shares available. The company plans to raise $98 billion to fund its AI initiatives. According to insiders, more than half of the common shares in this offering were allocated to long-term investors and existing shareholders. Among them, the top 15 largest subscribers collectively received about 70% of the shares issued. The offering was priced at $625 per share, a 2.7% discount compared with the closing price on Friday before the announcement. On Tuesday, Meta's stock fell as much as 1.4% in New York trading, to $621.47 per share. This stock offering is just one component of Meta's broader financing plan, which also includes issuing $12.5 billion of mandatory convertible preferred shares and a planned market‑based secondary offering. If the final fundraising reaches $98 billion, it would become one of the largest equity financings in history. (Bloomberg)
2nd place$Micron Technology (MU.US)$It closed up 2.77%, with trading volume reaching $21.125 billion.
In the second half of the year, market sentiment shifted, putting pressure on the stock prices of AI‑related component manufacturers such as semiconductor and memory firms, as investors began to question whether their massive spending commitments could be sustained. A positive factor for memory stocks is that valuations remain reasonable: Micron's forward 12‑month P/E ratio stands at 5x, making it the second‑lowest among S&P 500 constituents.
3rd place$NVIDIA (NVDA.US)$It closed up 0.90%, with trading volume at $18.348 billion.
According to ZDNet, Samsung and SK Hynix are preparing to supply NVIDIA's Rubin Ultra with 8-layer HBM4 in the second quarter of 2027, a move that could alter the original plan to adopt 12-layer HBM4E. Meanwhile, as reported by Wccftech, NVIDIA quietly reduced the HBM4 bandwidth specifications for its Vera Rubin platform as early as last September—cutting the bandwidth per Rubin GPU by about 13%, with the reduction reaching as high as 26% at the HGX Rubin NVL8 system level.
The aforementioned adjustments directly affect both HBM suppliers and the GPU industry chain. The lowered bandwidth threshold means that more HBM4 products are likely to pass NVIDIA's qualification, expanding potential supply sources; meanwhile, the introduction of an 8-layer configuration will reduce the cost and bill-of-materials burden per HBM stack, which, against the backdrop of persistently tight HBM supply, is expected to help alleviate capacity bottlenecks.

Currently available as a research preview to a select group of vetted testers, it will gradually roll out to Google AI Ultra subscribers and certain developers in the future. Google is exploring potential applications for this new model across gaming, film and television, and robotics, investigating how it can be integrated into existing workflows and where its capabilities lie.

14th place$Boeing (BA.US)$It closed down 10.69%, with trading volume reaching $8.089 billion.
Boeing's latest financial disclosure disappointed the market, sending its stock price sharply lower.
Boeing CEO Kelly Ortberg said on Tuesday that the company's target of achieving a monthly production rate of 47 737 aircraft will be delayed until early 2027, a significant postponement from the previous forecast.
Meanwhile, the company's guidance for free cash flow growth falls well short of Wall Street consensus: about $3 billion next year and roughly $6 billion in 2028, compared with analysts' prior estimates of $5.6 billion and $9.6 billion, respectively, according to LSEG data.
At the close, Boeing's stock plunged 10%, hitting its lowest level since April 2025.
15th place$Seagate Technology (STX.US)$It closed up 3.67%, with trading volume reaching $5.639 billion.
Driven by surging demand for AI‑related storage, Seagate posted first‑quarter revenue of $4.23 billion, up 61% year over year, with both earnings and its guidance for the next quarter comfortably exceeding expectations. Thanks to disciplined cost management, gross margin surged past 57%, and cash flow remained robust. The company regards HAMR technology as the cornerstone of its long-term growth. However, a nearly 150% year‑to‑date rally has elevated market expectations.
