Why PLSE stock is up today

PLSE stock surged 11.77% to $54.53 in a volatile session driven by a new buy rating from Freedom Capital and strong intraday momentum. The stock opened with a modest 0.8% gap up and climbed to a high of $58.90 before settling at $54.44. The move reflects renewed investor interest in the biotech firm following the initiation of coverage with a positive outlook.

What Happened

Freedom Capital Markets initiated coverage on Pulse Biosciences with a Buy rating and a $73 price target. This development came as the stock was already showing strength in the intraday session. The stock’s early buyers pushed it well above the prior close and into a new 52-week high. The COO, Liane Rae Teplitsky, has also been active in the market, buying shares on two separate occasions in late August and early September. These transactions suggest internal confidence in the company’s direction. The broader healthcare sector also saw movement, with Pulse Biosciences highlighted among stocks making significant intraday gains.
