Protagonist Therapeutics' CEO, Dinesh V. Patel, sold $7.5 million worth of common stock after exercising options. This transaction follows recent positive Q1 earnings, and contributes to a broader pattern of insider sales observed over the past 90 days. While exercising options and selling is a common practice for executives to realize gains, the magnitude of the sale by the CEO could be interpreted as profit-taking rather than a strong signal of future growth confidence, especially given the recent financial turnaround.
