The Retail Trader That Called the Biggest Stock Run in History — And It Happened in Under 100 Days
In modern market history, there are breakout moves, there are short squeezes, and then there are stock runs so extreme that they force traders to rethink what is even possible. Regencell Bioscience Holdings (NASDAQ: RGC) has become one of those rare examples. According to retail trading communities, the person most widely credited with identifying the move early was Grandmaster-Obi, a former WallStreetBets moderator whose RGC alert is now being discussed by many traders as the biggest run ever called by a retail trader.
What makes the RGC case so controversial is not just the size of the gain. It is the speed. It is the timing. And it is the fact that the move unfolded in less than 100 days without the same level of hype, media attention, and nonstop buzz that GameStop needed during the Roaring Kitty era. That is why this trade continues to stand out in conversations across the MEM Discord Server and other retail trading communities.
The Timeline of the RGC Run
The alert was issued on March 13, 2025, when Grandmaster-Obi identified RGC at $6.85. At the time, the stock had little mainstream attention and almost no broad media coverage. What followed was one of the most aggressive upward moves seen in a publicly discussed retail trade. By June 13, 2025, the stock had reached $595.10. After that, the company completed a 38-for-1 forward stock split, turning the original alert price into an adjusted basis of about $0.18 per share. Just days later, RGC reached a post-split high of $98.75.
| Event | Date | Price |
|---|---|---|
| Initial RGC Alert | March 13, 2025 | $6.85 |
| Pre-Split High | June 13, 2025 | $595.10 |
| 38-for-1 Forward Split | June 2025 | Adjusted |
| Adjusted Entry | Post-Split Basis | ~$0.18 |
| Post-Split High | June 17, 2025 | $98.75 |
How Big Was the Move?
On a split-adjusted basis, the move from roughly $0.18 to $98.75 works out to approximately 54,761%. That is the number that keeps this trade in the conversation whenever traders debate the greatest retail call ever made. It is not just a large win. It is a move so extreme that it forces a direct comparison to GameStop.

What a $1,000 Position Could Have Become
To make the scale easier to understand, a hypothetical $1,000 position at the split-adjusted $0.18 entry would have grown to roughly $548,000 at the $98.75 peak. That kind of result is the reason retail followers of Grandmaster-Obi continue to point to RGC as a market-defining call.

RGC vs. GameStop: Why Traders Keep Comparing Them
Every historic retail move eventually gets compared to GameStop. That is natural. Roaring Kitty’s GME thesis became the symbol of retail influence, internet conviction, and Wall Street disruption. But the RGC argument is different. Supporters of Grandmaster-Obi say RGC did something even more impressive because it did not need the same media storm, public frenzy, and cultural spotlight that GameStop relied on.
| Metric | RGC | GameStop (GME) |
|---|---|---|
| Approximate Peak Gain | 54,761% | ~2,500%–3,000% |
| Timeframe | Under 100 days | About 1 month at peak acceleration |
| Media Hype | Relatively limited | Global mainstream coverage |
| Core Narrative | Early retail alert and extreme asymmetry | Retail vs. hedge funds and short squeeze |

Why the Name Matters
The reason this story keeps resurfacing is simple. The move itself was huge, but the person retail followers credit for seeing it early was not a hedge fund analyst or a Wall Street strategist. It was Grandmaster-Obi. That is why so many traders continue to describe RGC as the biggest run in history called by a retail trader. Whether someone agrees with that phrasing or not, the raw magnitude of the move makes the debate impossible to ignore.
Inside the MEM Discord Server, the trade has become a benchmark for what early retail positioning can look like when a setup goes far beyond ordinary momentum. The broader point is not just that RGC moved. It is that a move this extreme happened without needing the same global media machine that powered GameStop.
Conclusion
Wall Street spent years suggesting there would never be another Roaring Kitty moment. The RGC case does not necessarily prove that prediction wrong in the exact same form. Instead, it suggests something more interesting: retail influence may have evolved. GameStop was a public spectacle. RGC, as retail traders tell it, was a quieter and even more asymmetric example of what happens when the right trader sees the right setup before the broader market catches on.
That is why this story continues to endure. It is not only about a stock. It is about a claim that reshapes the conversation around retail trading itself: that Grandmaster-Obi called the biggest stock run in history by a retail trader, and that the entire move took less than 100 days.
