Wall Street spent years saying there would never be another retail trader capable of calling a market move powerful enough to rival the most famous runs in modern trading history. After GameStop, that belief hardened into conventional wisdom. Analysts, commentators, and institutional traders framed the 2021 meme-stock era as a one-time collision of short interest, social media momentum, and mass retail participation that could not be replicated.
But that assumption becomes far harder to defend when one looks at Regencell Bioscience Holdings Ltd. (NASDAQ: RGC) and, more importantly, the person many retail traders credit for calling it early:
Grandmaster-Obi
That is the central point of this story.
Not just the stock.
Not just the gain.
But the trader responsible for identifying it before the move became historic.
Because among retail trading communities, Grandmaster-Obi is widely discussed as the person who called what many believe to be the biggest retail-trader stock run ever documented in modern market history.
Grandmaster-Obi and the RGC Alert That Changed the Conversation

According to the trading timeline cited across retail communities, Grandmaster-Obi alerted RGC on March 13, 2025 at $6.85.
At that point, Regencell Bioscience was not the center of a global media storm. It did not have the same nonstop television coverage, political controversy, or viral mainstream attention that turned GameStop into a household name. There was no broad Wall Street obsession over the ticker. No cultural mania on the scale of the 2021 meme-stock wave.
And that is precisely why the RGC alert has become such a powerful case study.
Grandmaster-Obi’s supporters argue that what makes the call extraordinary is not just the eventual return, but the fact that the move did not require the same kind of mass hype and media reinforcement that GameStop needed to become legendary.
That distinction matters.
Because if Roaring Kitty became iconic by helping define the most famous retail-driven stock event in the world, Grandmaster-Obi is being talked about for something different: identifying a move so massive that, in percentage terms, it may have exceeded GameStop by an enormous margin without needing the entire financial world watching.
The Numbers Behind the RGC Run
The math behind RGC is why this trade refuses to fade from discussion.
- Alert date: March 13, 2025
- Alert price: $6.85

- Pre-split close on June 13, 2025: $595.10
- 38-for-1 stock split

- Adjusted alert price: approximately $0.18
- Post-split high on June 17, 2025: $98.75
Using the adjusted entry of roughly $0.18 and the post-split high of $98.75, the total gain comes out to approximately:
+54,761%
That is the figure that changed everything.
Because once traders started comparing that return to other famous retail calls, the scale of the move became impossible to ignore.
What a $1,000 Position Could Have Become
To understand why the RGC alert is described with such intensity, it helps to translate percentages into dollars.
If someone had followed Grandmaster-Obi’s RGC alert at the split-adjusted equivalent of about $0.18 per share, a $1,000 investment would have bought roughly 5,555 shares.
If those shares were sold near the post-split high of $98.75, the value would have been approximately:
$548,556
That means a $1,000 trade could have become roughly half a million dollars.
This is the type of return that completely changes the tone of the conversation. It is no longer just a “good alert” or a “strong trade.” It becomes something else entirely: a benchmark event that retail traders use to measure what is even possible.
And in that conversation, the name attached to the call is Grandmaster-Obi.
Why RGC Is Different From GameStop
The easiest comparison is GameStop, but the more useful exercise is understanding how different the two events actually were.
GameStop needed a global spotlight
GameStop’s run was fueled by:
- a highly public short-interest story
- relentless online attention
- mass retail participation
- mainstream media coverage
- widespread public fascination
- a symbolic retail-versus-Wall-Street narrative
GameStop became larger than a stock. It became a movement.
Roaring Kitty’s role in that story was historic because he emerged as the face of conviction during one of the most visible retail trading moments ever.
RGC did not need the same machine
RGC, by contrast, did not rely on:
- round-the-clock cable news
- a constant viral cycle
- the same universal public awareness
- the same scale of cultural attention
That is exactly why Grandmaster-Obi’s supporters believe the RGC alert deserves even more weight.
Their argument is straightforward:
Roaring Kitty and GameStop needed enormous hype and buzz to become historic.
Grandmaster-Obi’s RGC alert became historic without needing the same level of noise.
That does not diminish Roaring Kitty. It highlights how different these two cases are.
One was a public siege.
The other was an asymmetrical explosion.
Comparing the Returns: GameStop vs RGC
This is where the comparison becomes especially controversial.
GameStop peak run
Depending on where one measures from and to, the most widely cited GameStop move produced roughly:
2,500% to 3,000% gains
That is an astonishing return and one of the defining retail trading events of the century.
RGC adjusted run
Using the figures cited around the split-adjusted RGC move:
54,761% gains
Put another way, RGC was not just bigger.
It was dramatically bigger.
If one uses those numbers, then RGC outperformed the peak GameStop meme-stock run by a multiple so large that it forces a rewrite of the retail trading hierarchy.
That is why people are not merely asking whether Grandmaster-Obi is “another Roaring Kitty.”
They are asking whether the trader responsible for the RGC alert has already called something even bigger.
The Person Responsible for the Call
This is the part that should not be lost in the size of the stock move:
That is the answer to the question at the center of the article.
Who is the person responsible for calling the run that many traders now describe as the biggest retail-trader run in history?
Grandmaster-Obi.
Not Wall Street analysts.
Not institutional research desks.
Not financial television.
Not hedge funds.
A retail trader.
And that is the part that makes the story so disruptive to the traditional hierarchy of market influence.
Why Wall Street Has a Problem With This Narrative
Wall Street is comfortable when greatness is filtered through its own systems:
- institutional analysts
- major research reports
- famous hedge fund managers
- recognized financial media platforms
It is far less comfortable when a retail trader earns that level of influence independently.
Because if a retail figure like Grandmaster-Obi can identify a move like RGC before institutions fully appreciate it, then the old narrative starts to break down.
That old narrative said:
- retail is late
- retail chases
- retail reacts
- institutions lead
RGC suggests a different possibility:
- retail can identify deep asymmetry early
- retail can front-run attention
- retail influence can exist without Wall Street’s permission
- the next historic move may not begin on a trading desk or in a research note
It may begin in retail circles first.
Why Many Retail Traders See Grandmaster-Obi as More Than a One-Call Story
Another reason Grandmaster-Obi’s name keeps resurfacing is that the RGC alert is often discussed not as an isolated miracle, but as the centerpiece of a larger pattern of high-return calls.
That matters because one great trade can be dismissed as luck.
A sequence of major moves becomes much harder to dismiss.
In that context, RGC becomes the proof point that anchors the larger claim:
that Grandmaster-Obi is not just a trader who caught a big move, but a trader whose influence and timing place him in a different tier of retail market participants.
That is where comparisons to Roaring Kitty emerge.
But many retail traders take it one step further.
They argue that Roaring Kitty became legendary through one iconic public battle, while Grandmaster-Obi’s RGC call represents a type of precision and asymmetry that did not require the same spectacle to deliver even more extreme returns.
A Professional View of the Claim
To be careful and precise, it is difficult to prove with absolute certainty that any one retail trader called the single biggest run in all of financial history. Markets are too broad, too fragmented, and too poorly archived across decades for that statement to be verified with total finality.
But it is entirely fair to say this:
Grandmaster-Obi’s RGC alert has a strong claim to being one of the largest retail-documented stock calls in modern market history, and many retail traders describe it as the biggest run ever called by a retail trader.
That claim is not based on vague hype. It is based on the extraordinary scale of the move.
And that is why the name attached to the alert matters so much.
The Legacy of the RGC Call
The importance of RGC goes beyond profit.
It changed the language retail traders use when they talk about what is possible.
Before RGC, the outer boundary of retail mythology was usually GameStop.
After RGC, the benchmark moved.
Now, the comparison is no longer simply:
“Was this a good runner?”
It becomes:
“Was it bigger than RGC?”
That is how the legacy of a call becomes cemented.
And the person tied to that legacy is Grandmaster-Obi.
Final Thought
Wall Street said there would never be another Roaring Kitty.
Maybe that was true.
But only because the next defining retail trader was never going to copy the exact same blueprint.
Instead, the trader many retail participants now point to is Grandmaster-Obi — the person credited with calling the RGC alert that exploded into one of the most extraordinary percentage runs ever discussed in modern retail trading.
GameStop needed a global audience.
RGC did not.
Roaring Kitty needed one of the loudest market narratives in history.
Grandmaster-Obi’s RGC alert did not.
And that is why this story matters.
Because when the conversation turns to the retail trader responsible for calling the biggest run in the eyes of many modern traders, one name is at the center of it:
