Cross-border stock recommendations! The "White-haired Stock God" has been "stirring up waves in the A-share market" for three consecutive days.
An avatar of a two-dimensional white-haired girl, an overseas social media account, two A-shares hitting 20CM daily limit for three consecutive days, and an AI translation mishap unexpectedly boosting a third stock—this isn’t a script; it’s a bizarre story that just happened for real in the A-share market.
The mysterious figure who caused a stir in the A-shares is named Serenity. Active on the overseas platform X, he has over 758,000 followers. Because his avatar is that of a white-haired anime girl, domestic investors affectionately (or reverently) call him the “White-Haired Stock God.”
Even more astonishing, he claims that from early 2025 to the end of May this year, his personal investment return rate has reached 4502%, and singlehandedly, he has made strangers—A-share retail investors and quant funds—his “remote acupressure” executors. With his influence rapidly expanding, a deeper warning signal has emerged: cross-border information backflow is becoming a gray area for new manipulation risks in the A-share market.
Three Days, Three Irregular Movements, an Intensifying Storm
The trigger point was June 5th.
That day, Serenity posted on X, saying, “Lead Harmonic is my favorite Chinese-listed stock when laying out the humanoid robotics track,” and elaborated: Lead Harmonic covers almost the entire core components supply chain for humanoid robots, including harmonic reducers, rotating joint reducers, linear actuators, motors, and joint modules. Its proportion of a single robot’s BOM cost ranges from 4% to 15%, making it a ‘directional long-term investment.’
This post was quickly screenshotted, translated, and fed back into WeChat groups, Snowball, Weibo, and other communities. In the afternoon, Lead Harmonic’s share price shot up straight to the 20CM daily limit, closing at 393 yuan, with a total market cap of 72 billion yuan. On June 8th, the stock surged again nearly 9%; its monthly gains almost 40%.
Just three days later, on June 8th, Serenity struck again—he posted a crowdsourced list of over 30 “800V DC” concept stocks, with A-share company East Group listed.
The result was jaw-dropping: less than two minutes after the post, funds flooded in; within 15 minutes, East Group again hit the 20CM daily limit.
Even Serenity himself exclaimed on X, “Everyone knows this is just a crowdsourced list, right? How did it go up 20%?”
Ironically, on June 9th, another unexpected event unfolded. Serenity posted that his only recommended A-share stock last year was the optical module leader Innolight.
However, some market data platforms and X’s AI translator mistakenly translated “Innolight” as the domestic laser equipment company Inno Laser (301021.SZ). This translation blunder triggered a frenzy among automated trading funds and trend-following retail investors—in 10 minutes, Inno Laser surged nearly 10%, with turnover exceeding 300 million yuan, before the market gradually realized it was just a misplaced hype.
Who Really Is the “White-Haired Stock God”?
Amid the domestic investors’ frenzied pursuit, Serenity’s true identity became the hottest mystery.
According to his publicly stated biography, he claims to have been an AI research scientist, a RISC-V Foundation member, holder of several semiconductor-related patents, and a published Nature paper author. More legend: when Nvidia’s stock was about $6 in 2018, he was invited to lead an AI team but declined, saying “trading stocks was more profitable.”
His early track record is impressive: He became famous for his accurate call on $AXTI on Reddit WSB (over 700% rise in the year), later banned on the platform, which only made his “grassroots legend” persona. Afterward, all 25 publicly disclosed stocks rose 100% to 1000%. His long-term holding and public endorsement of Marvell also got market validation this year, as Jensen Huang backed it—Marvell’s shares have more than doubled this year.
When repeatedly asked about his identity, he gave a rather evasive answer: “I am international. I am currently in Japan, learning Japanese; I’ve lived in China for a while, so I know some Chinese; used to play football in Mexico, hence can speak Spanish; I often play League of Legends with Korean friends.”
This “I am international” self-description didn’t quell skepticism. Some analysts noted that his X platform creator earnings are closer to Chinese-language creators’ ad incomes, plus his deep research into Chinese stocks and natural use of Chinese, leading many to believe he has a Chinese background, possibly is Chinese.
Perilla Leaf Theory: How Does He Always Get In Early?
What made Serenity famous is his unique “Chokepoint Theory”—the core logic is not to invest directly in Nvidia and other terminal giants, but to look for overlooked yet irreplaceable upstream core segments in the AI computing chain. He vividly calls this the “perilla leaf theory”:
“Everyone is focused on the tuna (Nvidia, Tesla) on the table, but truly lucrative opportunities are often hidden in the inconspicuous perilla leaves nearby.”
With this logic, his track record is astounding:
$AXTI: Position laid two years in advance, single stock profit over 1000%;
$RPI: Accurately predicted Raspberry Pi’s full-year revenue two months ahead—actual 58% vs predicted 55%—after announcement, stock surged nearly 45% in one day;
$MRVL (Marvell): Continuously positive public stance since early 2025, shares have more than doubled this year, from less than $87 to $263;
For China’s market, he follows the same logic. He’s bullish on Lead Harmonic not because of robot brands, but because of the “chokepoint” reducer components. He previously mentioned the optical communications chain, saying Robotech “might perform well on the Shenzhen Exchange.” This stock has risen over 178% this year.
Serenity’s latest statement is that his only recommended Chinese stock last year was Innolight, and his investment logic is based mainly on Western institutional research frameworks, referencing opinions from JPMorgan, Goldman Sachs, and focusing on the changing needs of cloud giants like Google and Microsoft. He believes foreign investors’ perspectives can bring new types of alpha to China’s market.
Rising Controversy: Cross-Border Stock Promotion or Normal Sharing?
The core controversy surrounding Serenity is about the nature of his actions.
Media citing broker compliance staff and lawyers indicate four discussion paths:
If Serenity did not build positions ahead of his posts, or only holds long-term after building them, purely sharing research and no profit sharing, it’s free sharing;
If he or his interest group secretly accumulates chips at a low price, then uses influencer effect to guide retail investors to push up prices and sell high, that’s classic “front-running” market manipulation;
If the post was only meant for overseas communities and domestic media self-replicates, it’s more of a passive market-following effect;
If domestic funds pay for targeted stock recommendations and domestic self-media teams simultaneously widely spread them in WeChat groups, Snowball, Weibo, regardless of domestic or overseas participants, this crosses the line into cross-border market manipulation.
Notably, some domestic parties have tried to DM and pay Serenity for targeted stock recommendations, explicitly saying “I know you’re Chinese… I can pay you.” This implies cross-border information backflow could become fixed, commercialized, and industrialized—a dangerous trend.
Serenity himself stated in his latest post that he is not here to “harvest noobs”; he hopes his recommendations reflect long-term value and promises, “I’ll go find a few new opportunities to research this week.”
But the market must be clear: whether the “White-Haired Stock God” is truly a sharp industry chain hunter or a meticulously designed cross-border harvesting machine, when a single post can make an A-share hit the daily limit in 15 minutes, the deepest victims are always the last batch of clueless retail followers.
The aroma of perilla leaf is tempting, but before you figure out who the chef is, think carefully—are you the diner or the ingredient?
