A whale’s $30 million tech stock trading plan: AMD plans to close short positions and go long, while Micron and SanDisk will wait for a rebound to open short positions.

South Korea’s stock market posted sharp declines today, with SK Hynix plunging over 8% and Samsung Electronics falling more than 7%. Some analysts attribute the sell-off to a recent bearish report on memory chips released by Shawn Kim, head of Asia Tech Research at Morgan Stanley, though others argue the report may not be the direct cause of the market drop. In his July 21 report, Kim noted that the AI-driven memory chip boom is nearing an inflection point, with memory contract prices likely to peak in the fourth quarter, and the share of upward earnings revisions has dropped from 92% to 77%. The report also pointed out that NAND module manufacturers’ inventories have risen to around 13 weeks, approaching the peak of roughly 15 weeks recorded during the pandemic, and put forward the trading logic: "Sell DRAM when NAND turns down." Separately, Morgan Stanley was excluded from the joint lead underwriter lineup for SK Hynix’s roughly $265 billion American Depositary Receipt (ADR) listing. The selected underwriters are Bank of America, Citigroup, Goldman Sachs, and JPMorgan Chase, leaving Morgan Stanley as the only top-tier investment bank left out. At a 0.5% underwriting fee rate, the total commission for the project is approximately $130 million. Multiple banking sources said Morgan Stanley’s Seoul office has launched internal reflection on whether its consistent negative semiconductor reports have harmed its investment banking business. Beyond the SK Hynix deal, Morgan Stanley has recently been embroiled in disputes over SpaceX’s share placement and the sale of IGIS Asset Management in South Korea. These incidents further highlight the tension between the research department’s independence and the commercial interests of investment banking, and have amplified its reputation and business pressure in the South Korean market.

According to Bitget data, the Nikkei 225 index closed down 2.73% to 64,611.15 points. South Korea’s KOSPI index closed down 5.73% to 6,690.02 points. SK Hynix fell 8.33% at close, while Samsung Electronics dropped 7.59%.

Whale "Xian Ding 10 Big Goals" stated in a post that after closing its short positions, it quickly re-established long positions, as its medium- to long-term bullish view on Bitcoin remains unchanged. It believes the key dividing zone of the last bull market is around $60,000, and Bitcoin’s current mainstream mining cost is also concentrated between $50,000 and $60,000. Last month, Bitcoin dipped to $58,000 before rebounding rapidly, further confirming the support capacity of this zone. Over the past month, Bitcoin has undergone sufficient consolidation and turnover in the $58,000–$63,000 range, and has re-stabilized near $66,000 after a pullback. Provided there are no systemic risks or major fundamental changes, the risk-reward ratio of chasing short positions at current levels is no longer favorable, and the market may see a volume-driven rally that breaks through $72,000. If the market structure does not change significantly, Bitcoin has a high probability of retesting $100,000 around March next year. Currently, US stocks—especially AI-related sectors—are trading at relatively high valuations and may face significant volatility going forward. Bitcoin’s correlation with US stocks has decreased notably compared to previous cycles, and it is gradually moving toward an independent trend. The whale has set a trading invalidation zone for its current positions: if the market falls back to $61,500–$64,000 and the trend proves its judgment wrong, it will immediately close positions to control losses. It emphasized: "Views can be adjusted, but discipline must remain unwavering." Additionally, the latest public data shows that the whale "Xian Ding 10 Big Goals" has set the position of its Binance real futures account "Jason leo133" to private.

Crypto derivatives trading platform BitMEX faced a class-action lawsuit on the same day it announced it would cease operations in September, accused of manipulating users’ forced liquidations and profiting via internal trading privileges and system mechanisms. BKX Services Inc. and David Namdar filed the suit Thursday with the U.S. District Court for the Southern District of New York, alleging BitMEX fraudulently designed its liquidation mechanism, resulting in total user losses of 622.66 BTC. BKX claims losses of at least 305.81 BTC, while Namdar says his losses exceed 316.85 BTC. The plaintiffs allege BitMEX’s internal trading team accessed users’ private transaction data and continued trading while regular users were unable to close positions due to server freezes, profiting from forced liquidations. Court documents state BitMEX allowed users up to 100x leverage; when a user’s position triggered liquidation, the platform executed automatic liquidation even if collateral value remained higher than actual losses, transferring the remaining BTC to its insurance fund. The plaintiffs are seeking return of the withheld BTC, compensatory and punitive damages, and aim to represent U.S. users who traded BitMEX’s BTC swap products since July 23, 2018. The lawsuit has reignited longstanding external controversy over BitMEX’s liquidation mechanism. Previously, a class-action lawsuit over similar allegations was filed by users in 2020; that case was voluntarily dismissed on June 30, 2025, and does not preclude future filings.

Morgan Stanley strategists said in a report that recent data indicates the Federal Reserve will hold steady at its July policy meeting and likely maintain interest rates unchanged for the rest of the year. They wrote: “The Fed is losing patience with inflation above its target. The trajectory of inflation in the coming months is critical—we expect inflation to cool as anticipated—otherwise the Fed may pivot to raising rates later this year.” Currently, money markets have priced in expectations of nearly two Fed rate hikes by the end of the year. However, the slowing inflation trend may prompt the Fed to hold rates steady this year, keeping the federal funds rate in the 3.50% to 3.75% range. “We expect the downward trend in inflation will keep the Fed on hold this year.”

Tesla and SpaceX founder Elon Musk told *The Economist* in a 90-minute interview that artificial intelligence (AI) could surpass human intelligence within the next five years, and predicted that AI and robots would push the world into an "era of high prosperity" in roughly a decade. Musk argued that once AI systems and robots have sufficiently advanced digital intelligence and production capacity, the global economy could approach a state of "infinite supply", making human work no longer a necessity for survival and gradually reducing the importance of currency. He noted that with enough robots in the future, society would have a "quasi-infinite economy" where AI can produce more goods and services than humanity can consume. He even predicted that by around 2036, the traditional monetary system would likely see its importance decline significantly. On future economic operation models, Musk said governments may maintain social function by distributing funds directly to the public, adding that AI-driven productivity gains could lead to deflation rather than inflation. However, Musk acknowledged that issues including corporate profit models, government fiscal sources, and social transformation mean the AI era’s economic structure could differ drastically from traditional economic laws. Additionally, Musk discussed the integration of AI and space development, stating that future AI computing could be supported by space-deployed data centers, and reiterating his long-term plan for human exploration of Mars. During the interview, Musk also reflected on his prior involvement with the Trump administration’s Department of Government Efficiency (DOGE). He admitted to investing too much energy in politics, saying he "got sidetracked" in some areas, and noted that if given the choice again, he would likely devote more time to his own companies.
