Planet Fitness Inc A (PLNT) rose 6.02% to $53.68 on August 18, driven by a combination of analyst upgrades and insider buying. The stock opened at $50.40 and climbed steadily through the session, reaching a high of $53.70 at 3:35 PM ET. The move follows a recent price target increase from Morgan Stanley and a purchase of 10,000 shares by director Stephen Spinelli.
What Happened
Morgan Stanley raised its price target for PLNT to $51 from $47, signaling increased confidence in the stock despite ongoing challenges in member growth. Meanwhile, Stephen Spinelli, a director of Planet Fitness, purchased 10,000 shares for $492,800 on August 10, marking a 28% increase in his stake. This buying activity suggests continued confidence in the company’s long-term prospects. The stock is also the subject of multiple securities class action lawsuits, with several law firms encouraging investors to seek counsel ahead of key deadlines in September 2026. Despite these legal developments, the stock has shown signs of recovery, having recently reported better-than-expected Q2 earnings and raised its fiscal year 2026 adjusted EPS guidance.
What The Data Shows
PLNT traded at 1.0 times its 3-month average volume, with 1.0 million shares changing hands. The stock reached a session high of $53.70, just below its 52-week high of $114.26. The company has a market cap of $3.8 billion, a P/E ratio of 17.1, and trailing 12-month revenue growth of 11.6%. Net margins remain strong at 18.3%. The stock has printed 54 fresh 52-week highs on the day, indicating broad retail and institutional interest.
What To Watch
The stock is set to report no earnings in the near term, but coverage breadth will remain key. Analysts from RBC Capital and Morgan Stanley have issued recent ratings, and further commentary from the investment community could influence the stock’s trajectory. Retail traders and institutional investors alike will likely monitor any new developments in the ongoing class action lawsuits and insider activity.
