Seaport Therapeutics is exploding higher today, hitting a new 52-week high of 28.58 as the stock continues to trade significantly above its 50-day moving average. While there is no company-specific news driving the move, the broader healthcare sector has seen positive momentum recently, supported by gains in major industry players like Merck and Johnson and Johnson. This upward trend follows a period of notable regulatory activity in the biotechnology space, including recent FDA approvals for rare disease therapies and new drug combinations that have bolstered investor sentiment across the sector.
