25-year-old Silicon Valley AI stock prodigy hunted down by Wall Street and liquidated 📉
Leopold, a post-2000 trader, previously worked at FTX and OpenAI's super alignment team. After leaving Silicon Valley, he founded the SA hedge fund, which peaked at $45 billion in assets under management, with extremely exaggerated short-term returns.
His trading logic is very clear: AI continuously iterates, constantly consuming computing power and storage hardware. Hardware is a more deterministic "water-selling" sector, while upper-layer software is highly competitive. Therefore, he heavily invested in storage and computing power targets, shorted SaaS software, and used TRS tools to leverage returns by 4x over the long term.
The full collapse process:
- In July, the market showed extreme divergence; AI hardware collectively plunged, with heavy holdings in SK Hynix and Micron sharply retreating;
- Shorted software stocks like Adobe rose against the trend, causing losses on both sides of the account.
- Multiple prime brokers simultaneously demanded margin calls, heavy holdings faced coordinated selling pressure, and liquidity dried up.
- Within 72 hours, he liquidated 16 billion in secondary market chips at a discount; the chips were bought cheaply by Citadel. After liquidation, the storage sector immediately rebounded, precisely cutting at the bottom.
Now the fund has exited secondary market leveraged trading, retaining only primary market equity, and Leopold has announced he will no longer use high leverage.

Capital markets have never lacked correct long-term strategies. Many understand cycles and grasp trends, but ultimately fail due to short-term capital manipulation and liquidity suppression tactics.
As the old saying goes, one can survive great rivers and waves but easily capsize in a gutter—this fits trading perfectly.
Aggressive leverage and long-short hedging seem to amplify returns but actually greatly reduce error tolerance.
Still the same truth: massive capital carries an inherent original sin, anytime, anywhere.
In the end, trading is never about explosive power but about stability and longevity. Low leverage, non-aggressiveness, and minimal speculation are the eternal survival rules.

The South Korean government has intervened to stabilize the market
The South Korean government plans to inject 20 trillion KRW (approximately 13.9 billion USD) into the sovereign wealth fund Korea Investment Corporation (KIC), specifically for strategic investments in artificial intelligence, data centers, and infrastructure sectors.
Last night, US stock storage rebounded, and this morning KOSPI followed suit with a rebound. Even the major indexes fluctuated by more than ten points, like altcoins~
Here, Changxin also surged sharply, with its market value peaking above 4 trillion.
By the Han River, Korean retail investors who were "debt investing" yesterday feel like they bet right today.
A single bullish candlestick is more invigorating than ten bowls of ginseng chicken soup.
Koreans inherently have a "win it all or lose it all" gambling nature—whether in real estate speculation, crypto trading, or AI speculation.
Extremes are the very essence of Korea, and the candlestick chart just paints that essence.
Panic and euphoria are always two sides of the same coin.
When flipping too fast, even you can’t tell which side is up.

US stock storage chip stocks collectively surged, with SanDisk's stock price increase expanding to 24%, ending a consecutive 4-day decline. Seagate Technology rose over 16%, Western Digital rose over 15%, Micron Technology rose over 17%, SK Hynix rose over 17%.
SK Group Chairman Choi Tae-won bought 3,620 shares of Korean SK Hynix common stock.
Tomorrow $CXMT will undoubtedly hit a new high, the question is how high it will go? Personal estimates:
First target: 4 trillion market value (¥59.74);
Second target: 4.5 trillion market value (¥67.2);
Third target: 5 trillion market value (¥74.67)..
The probability of reaching the first target is very high, the second target probability is 50%, and the third target probability is 5%.
U.S. tech stocks collectively surged significantly in pre-market trading $MU $SNDK $SKHY , which is a positive sentiment boost for the A-share computing power and semiconductor sectors, increasing the probability of a recovery in the tech sector tomorrow.
However, it is important to recognize that the external boost is mostly a short-term emotional catalyst and is unlikely to directly reverse the medium-term downward trend. Focus on observing the strength of incremental funds in the early session and be cautious of a high open followed by a decline.
It is not advisable to heavily bottom-fish during the rebound game; holders can flexibly adjust their positions during the recovery opportunity and maintain good risk control

The Prisoner's Dilemma of US, China, and South Korea Tech Stocks:
The three parties' tech stocks are trapped in the same "interrogation room": US tech giants fear falling behind and are aggressively pouring capital into AI; South Korean retail investors are holding leveraged ETFs stubbornly, backing Samsung and SK Hynix; Chinese A-shares are scared retail investors will sell first, so they "sell first as a courtesy." Everyone is rushing to protect themselves, causing a collective stampede.
They could have jointly supported the AI bull market, but mutual suspicion has led them all to fall into a death spiral.

What I admire most in this wave is still 0xsun's intuition
On June 16, retweeted SPCX at $226 per share
On June 20, mentioned the historical peak of storage
On July 8, bottom-fished 280M ANSEM and 6M NEST
From July 12, started closely watching 180M cashcat
Every wave accurately predicted the highest point for you, that's the power of your brother Sun
