According to BlockBeats, on July 30, well-known trader Ouyang Zhaibai posted, "Continuing to take orders today." The screenshot he shared showed a dense series of tiered limit buy orders for SK Hynix ADR in the range of approximately $122 to $94.

Previously, he had stated that the biggest trading opportunity of the year had arrived, and he began to buy up storage concept stocks at the bottom by using a step-by-step approach without setting stop-loss orders.

Ouyang Zhaibai has long employed a low-leverage trend trading strategy, the core of which includes "going long on genuine breakouts," short-term responses to extreme market sentiment, and strict position control, with total leverage typically not exceeding 2 times. His trading philosophy emphasizes achieving compound interest through trend-following holding and periodic bottom-fishing, and prioritizes staying in the market, opposing high leverage and full-margin trading.

According to BlockBeats, on July 30th, the foreign exchange research team at Commerzbank pointed out that after the Federal Reserve kept interest rates unchanged but significant internal divisions were exposed, the US dollar index fell and the euro rose. The weakening dollar, coupled with market pricing in a September rate hike and rising long-term US Treasury yields, collectively fueled the gains in the US and European markets, reflecting a shift in market expectations regarding US monetary policy. The bank's analysts stated, "The fact that three officials voted against a 25 basis point rate hike highlights growing concerns about persistent inflation."

The market interpreted the decision as less hawkish than the dissenting votes suggested, pushing down the yield on the 2-year U.S. Treasury note and the dollar. However, long-term yields rose sharply as investors perceived the Fed's response as insufficient to curb persistent inflation. Federal funds rate futures indicate a 63% probability of a 25 basis point rate hike in September. The market has already lowered its cumulative rate hike expectations for the year from 42 basis points on Tuesday to 33 basis points. (Jinshi)

According to BlockBeats, on July 30th, Bitget data showed that the South Korean KOSPI index closed down 1.35% at 5586.81 points. SK Hynix fell 5.6%, and Samsung Electronics fell 0.7%. Meanwhile, the Nikkei 225 index closed up 0.71% at 61867.43 points.

According to BlockBeats, on July 30th, renowned trader Doctor Profit posted that he decided on July 18th to take profits on his Bitcoin short position established around $120,000, while maintaining his stock short positions. Although he still anticipates a potential broader market decline, he has begun dollar-cost averaging into BTC and ETH.

The current correction is primarily concentrated in the AI sector, with many AI stocks experiencing significant declines. BTC, however, remains stable within its range, and ETH has shown considerable resilience. The S&P 500's impact on BTC is currently relatively limited. While it's too early to draw conclusions, this may support the initial assessment that the main correction is likely focused on AI stocks, rather than a large-scale sell-off in BTC and ETH.

Doctor Profit stated that its short positions in stocks currently include MicroStrategy (-64.8%), Coinbase (-51.8%), SanDisk (-49.4%), Palantir (-40.6%), Netflix (-34.3%), IBM (-32.2%), Microsoft (-28.2%), and Nvidia (-8.6%), resulting in significant unrealized profits. Apple (+26.2%) and the S&P 500 (+4%) are detrimental to its positions. He added that he invested in Coinbase last week, so the current Coinbase short position is primarily for hedging, and he plans to gradually close out the position and lock in profits over the next few weeks.

According to BlockBeats, on July 30th, AI trading recently experienced a sharp cooling, with high-beta assets across the board under pressure, from US stocks to Asian tech stocks. The Nasdaq 100 has clearly retreated from its highs, with many AI infrastructure, cloud computing, power, and semiconductor supply chain stocks experiencing double-digit declines. South Korea's KOSPI has amplified this sell-off, with the index retreating nearly 40% from its mid-June high, and its intraday maximum drop approaching 44%. Previously favored by investors, the AI computing power chain is undergoing a rapid deleveraging and valuation reassessment.

In this context, even the once-renowned "stock market gurus" failed to protect themselves from the market downturn. According to the Financial Times, Situational Awareness, the AI-themed hedge fund founded by former OpenAI researcher Leopold Aschenbrenner, is seeking new funding. Following the recent sharp correction in AI-related stocks, this fund, known for its highly concentrated bets on the AI industry chain, has suffered significant losses and is seeking to replenish capital through investor communications and potential asset sales.

This fundraising quickly became a landmark event in the wake of the AI deal frenzy. Over the past year, the market was willing to pay high valuations for computing power, chips, electricity, and cloud infrastructure; however, with the sharp fluctuations in the South Korean KOSPI, the Nasdaq 100, and many AI infrastructure stocks, funds began to re-examine the return cycle, leverage risk, and crowded positions in the AI industry chain.

Similar drawdowns have also occurred with Serenity, the "white-haired stock god" familiar to the Chinese investment community. Serenity is an anonymous trader active on the X platform, and no regulatory documents disclose his full holdings, making it impossible for outsiders to confirm his true positions and portfolio weights. However, he has previously discussed his AI supply chain framework publicly on multiple occasions, stating that his portfolio focuses on "AI bottleneck" segments such as storage, photonics, robotics, and upstream semiconductors.

Serenity's meteoric rise to fame stemmed from his early identification of highly volatile stocks deep within the industry chain. He specifically highlighted companies like SIVE, NBIS, AXTI, and CCXI, covering sub-sectors such as CPO light sources, InP materials, AI cloud, and humanoid robots. In favorable market conditions, these stocks exhibit significantly higher volatility than mainstream tech stocks, propelling Serenity to legendary status on social media.

However, the backlash from highly volatile assets was equally severe. In mid-July, Serenity stated on X that his portfolio had suffered a maximum drawdown of 49.4% this month following the recent market crash. He later explained that with 1.4x leverage and the underlying assets of his heavily weighted storage and photonics sectors falling by an average of about 35%, a portfolio drawdown of nearly 49% was not unexpected.
