Unveiling Serenity’s 45x Return Legend

In a corner of Reddit best known for YOLO trades and meme stocks, Serenity stands apart. While most WallStreetBets regulars chase momentum with emotion and max leverage, this trader spent years quietly studying supply chain choke points — and it's paying off.

Chinese investors have given him a nickname: the AI supply chain detective with the white-haired anime avatar.

No luxury cars. No private jets. Just a white-haired anime girl as a profile picture, and analysis that is entirely data-driven. What Serenity publishes — in Chinese, English, and Japanese — is the kind of deep structural research that most retail investors don't bother with.

On May 27, 2026, Micron (MU) crossed a $1 trillion market cap for the first time. The same day, Serenity's year-to-date return came in at 4,502.45%.

The investment thesis

Serenity's core view: trying to pick the winning AI application is a fool's errand. His approach is different. Instead of chasing the gold rush, find the companies that sell the shovels — specifically, the ones no one else can replace.

He ignores the most-hyped large-caps and hunts for small-cap bottleneck plays buried deep in the AI semiconductor supply chain. His framework comes down to one word: chokepoints.

• Irreplaceable components: Low-profile companies with dominant global capacity, high technical barriers, and real pricing power.

• Logic over noise: He researches enterprise CapEx cycles, CoWoS packaging bottlenecks, HBM supply-demand imbalances, technical substitution difficulty, and the interdependencies between supply chains — not price charts or market sentiment. All of them are published free, for anyone to read.

The results have caught attention fast. In a single month, his follower count on X jumped from 50,000 to nearly 400,000.

The calls that made him famous

A few pinned posts across Reddit and X explain why so many retail investors are copying his trades.

AXTI: the banning that became a legend

Before the following came, Serenity posted on r/wallstreetbets under the name AleaBito. He wrote a long, detailed thesis on AXTI — a small-cap making indium phosphide (InP) substrates, trading at $12 with a $200 million market cap.

The community didn't buy it. His account was permanently banned.

Then AXTI ran from $12 to $70. The banning became a founding myth.

Micron (MU): the trillion-dollar call

MU broke $1 trillion on May 27. Serenity had called it months before:

"Micron (MU) finally reached $1 trillion market cap. I said before that it looked like the next Nvidia (NVDA) because AI demand for memory (HBM) is structural. This stock has probably created countless millionaires – up from $80 to $887."

SIVE: positioning for the EU Chips Act

On May 27, the EU formally advanced the European Chips Act 2, with photonics as a primary focus. Serenity had already taken a public position:

"FYI, the European Chips Act 2 lands today (May 27). This one is expected to specifically target photonics. There's a leading European photonics and laser company in Sweden called SIVE. It's also funded under the US Chips Act and is critical to the Western supply chain."

AAOI: the full-stack laser play

Serenity's view on AAOI: it covers the full value chain from laser design through assembly to transceiver sales, and it holds ELSFP technology that gives it a direct seat at the CPO table. He went public with a buy near $84 and said the optical transceiver business would grow 10x in the second half of 2027. When a short report came out, he was direct: "If you weren't around for AXTI swinging 25% every day, don't talk to me about volatility."

The track record

Serenity's verified list of past calls spans AI servers, HBM, advanced packaging, optical modules, power management, and semiconductor materials.

Every name on the list — each one a chokepoint play in its respective niche — returned between 100% and 1,000%+ after his posts.
