A 10% owner of Diametica Therapeutics purchased over $11 million in stock around $6 per share, mirroring a past buy that led to the stock doubling. The CEO and CIO of Triple Point Venture Growth also showed strong conviction by collectively buying $7.7 million of their company's stock in the last few weeks. Conversely, the CEO of Frontier Group Holdings (ULCC) sold $3.55 million after a 50% rally; historically, his sales have preceded an average 40% drop within three months. Key executives at Par Pacific Holdings (PARR) are also selling after a 100% gain, and their last coordinated sale preceded a 60% stock decline. These significant insider sales in ULCC and PARR suggest caution is warranted after their recent sharp price increases.
