  • Amazon Rises 2.5% in Pre-Market Trading Ahead of Q2 Earnings, AWS Growth Becomes Key Focus

    On July 30, Amazon (AMZN.US) rose 2.5% in pre-market trading. In terms of news, Amazon is set to release its second-quarter results after the U.S. market closes on July 30 (Beijing time July 31).

  • Goldman Sachs: Asian Equity Hedge Funds Face Record Monthly Drawdown Due to AI Stock Plunge

    A report from Goldman Sachs on July 30 shows that equity hedge funds focused on the Asian market are facing their largest single-month drawdown on record, as a broad sell-off in AI concept stocks wiped out most of the gains from previous concentrated bets on the sector. According to Goldman Sachs, as of July 28, fundamental long-short equity hedge funds focusing on Asia fell an average of 18.6% this month. In the first half of the year, these funds were among the best-performing globally due to early bets on AI hardware leaders, including South Korean chipmakers SK Hynix and Samsung Electronics. Some funds posted returns of over 100% at one point. However, the market has now undergone a sharp reversal. Goldman Sachs noted that since the year-to-date return peaked at 40% on July 22, these funds have given back 21 percentage points of their year-to-date gains. The bank pointed out that the crowded AI trades that drove significant gains in the first half are now becoming the main factor behind the unusually large drawdown this month. Specifically, funds with higher exposure to AI themes suffered greater losses. Amid the market turmoil, hedge funds have been taking profits and reducing risk. According to Goldman Sachs data, as of July 27, Asian hedge funds have reduced exposure for eight consecutive trading days, with the five-day cumulative reduction in gross exposure hitting a record high.

  • Korea Exchange Inspects Technical Feasibility of Temporary Short Selling Ban and Price Limit Reduction

    On July 30, according to Yonhap News, the Korea Exchange conducted an internal review on July 29 of the technical feasibility and system requirements for temporarily banning short selling and reducing the price limit (currently 30%), in response to recent severe volatility in the stock market. A person familiar with the matter said, "It only confirmed technical feasibility," emphasizing that it was not a step toward implementation, but rather a review among available contingency measures. Recently, the Korean stock market has been in a sustained decline, aggravating losses for individual investors. During a meeting of the National Assembly's Steering Committee, multiple lawmakers urged authorities to consider a temporary ban on short selling and restarting the securities market stabilization fund. A national petition to suspend short selling garnered over 10,000 approvals within two days of its public release. However, banning short selling conflicts with South Korea's goal of being included in the MSCI Developed Markets Index, as a previous 17-month short selling ban from November 2023 to March 2025 led MSCI to downgrade South Korea's market accessibility rating. The Korea Exchange officially stated that it had not received any related request from the government and had not formally discussed a short selling ban.

  • Graphics Card Prices Skyrocket 1,000 Yuan in a Day

    July 30, according to CCTV Finance, with the surge in AI computing power demand, the global storage chip market is experiencing severe supply shortages. In Shenzhen's Huaqiangbei area, the price transmission effect is clearly visible. Multiple merchants in Huaqiangbei reported that following Nvidia's latest round of price hike notices to authorized graphics card manufacturers, all major graphics card brands have fully implemented warehouse closure policies, temporarily halting bulk shipments, leading to a rapid tightening of spot supply across the entire circulation chain. Visiting several computer assembly shops in Huaqiangbei, it was learned that due to the unavailability of new stock, existing inventory has become a 'scarce resource,' with channel distributors generally reluctant to sell, driving up the prices of available inventory. Statistics show that prices of mainstream storage products and graphics cards in Huaqiangbei have been climbing continuously. For example: 1TB solid-state drives rose from 410 yuan in September last year to 950 yuan now, an increase of 132%; 16G DDR5 memory rose from 450 yuan in September last year to 1,850 yuan now, an increase of 311%; 32G DDR5 memory rose from 900 yuan in September last year to 3,800 yuan now, an increase of 322%. In terms of graphics cards, the RTX 5060 rose from 2,300 yuan on July 22 to around 3,000 yuan, an increase of about 30%; the RTX 5080 rose from 8,000 yuan on July 22 to around 12,000 yuan, an increase of about 50%.
