Silo Pharma (SILO) isn't your typical market mover. But on Tuesday, this small-cap biopharma stock defied expectations, skyrocketing over 123% to become the undisputed champion of U.S. gainers. The secret weapon? An exclusive global license agreement for a promising Alzheimer's drug.

Wednesday's pre-market trading painted a different picture as the stock fell by as much as 13%, suggesting some investors are taking profits after the wild ride. However, at around 11 am ET, shares had rebounded, gaining over 2%.

But hold on, the story doesn't end there. SILO is still capturing retail investor attention like never before. Stocktwits data reveals a surge in interest: the stock has the most new watchers in the past 24 hours, and follower counts have skyrocketed by a whopping 453% over the past week.

The excitement stems from a licensing deal for SPC-14, an Alzheimer's drug currently in preclinical development. Silo Pharma plans to leverage the FDA's streamlined pathway, potentially speeding up clinical trials and reducing costs. 

With the global Alzheimer's treatment market expected to reach a staggering $30.8 billion by 2033, the potential is undeniable.

Retail investors on Stocktwits are buzzing, bullish about the deal's potential to supercharge SILO's value. This comes on the heels of a similar licensing agreement for their lead drug candidate targeting stress and PTSD. 

With shares already up 57% year-to-date and hitting 11-month highs, the latest development could still trigger a retail frenzy for SILO over the longer-term, despite the pre-market dip.
