According to Cailian Press, investors who win the IPO allotment for Changxin Technology’s current offering will receive one lot of 500 shares, requiring a total payment of 4,330 yuan. Under four valuation scenarios—conservative, neutral, optimistic, and ultra-optimistic—Changxin Technology’s valuation would reach 1 trillion yuan, 1.5 trillion yuan, 2.3 trillion yuan, and 4.25 trillion yuan respectively. Based on the estimated market capitalization range of 1 trillion to 4 trillion yuan, its first-day post-listing price increase is projected to fall between 70% and 600%. Compared to the issue price of 8.66 yuan, the profit potential per lot is approximately 3,000 yuan to 26,000 yuan.

Bank of America (BofA)’s latest investor survey reveals market sentiment toward AI capital expenditure is growing more nuanced. Most investors do not think the AI spending boom has peaked, and still expect this wave of expenditure to continue in the second half of the year. At the same time, concerns are rising over hyperscalers’ excessive spending pace, debt pressure and credit risks. The survey shows investors are not broadly betting on the end of the AI cycle. Instead, the market still believes large platforms including Microsoft, Amazon, Alphabet and Meta will keep expanding investments in data centers, GPUs and power infrastructure. The problem is that the pace of capital expenditure growth has become so fast that some investors are starting to worry about free cash flow, share repurchase capacity and balance sheet flexibility. Per BofA’s survey methodology, AI has evolved from a pure growth story to a capital discipline issue. Over the past two years, the market rewarded companies for heavy AI investments; now, investors are starting to question the return periods of these investments, depreciation pressures, and whether cloud providers will be forced into overbuilding amid competition.

The U.S. Trade Representative (USTR) said local time on the 15th that, pursuant to instructions from U.S. President Donald Trump, U.S. Trade Representative Greer is taking final action under Section 301 of the Trade Act of 1974 to impose a 25% tariff on certain Brazilian goods. The decision stems from a year-long USTR investigation, which found that certain measures taken by Brazil in areas including digital trade and electronic payment services, unfair preferential tariffs, interference in anti-corruption law enforcement, intellectual property protection, ethanol market access, and illegal deforestation constitute "unreasonable practices" that have imposed burdens or restrictions on the business activities of U.S. farmers, workers, innovative enterprises, and exporters. Greer stated: "Despite extensive negotiations between the U.S. and Brazil over the past year, these issues have not been resolved. The U.S. remains willing to continue negotiations with Brazil to address the long-standing problems identified in this investigation." The U.S. will exempt Brazilian beef and coffee from the new 25% tariffs imposed on certain Brazilian goods. (Jinshi)
