Planet Fitness (PLNT) shares of the gym franchise are forming a high tight bull flag as the new year approaches and often can be a seasonally strong time of year for the fitness and health related companies like PLNT which sees an influx of new customers with new years resolutions. PLNT has coiled right near the 100 round number level since the strong November earnings gap up and drift higher. A move through 101 likely can push to 105 and beyond with the large 6000 January $100 calls bought last month still holding in open interest which was an adjustment from the Nov $85/$100 call spreads.
