$Universe Pharmaceuticals(UPC.US) surged +311% in a single day. The company announced an all-stock acquisition of Best Praise International for approximately $10.75 million, with a consideration of 4.4 million Class A shares, securing five Chinese patents covering geriatric degenerative diseases, cardiovascular, antibacterial, and drug delivery technologies. The intraday range was $2.60 to $12.22, closing at $8.80, up +238% from the day's low.

The combination of three factors—traditional Chinese medicine derivatives + the story of elderly health care + dilution from patent acquisition + low liquidity in micro-cap stocks—almost entirely drove today's gains, fueled by valuation repricing and retail FOMO. Before the deal closes in Q3, the interim period between announcements is prone to severe volatility. It's highly likely that half of the gains will be given back within two weeks.
