- The article does not provide any evidence or data to support the claim that insider purchases indicate confidence or concern around a company's prospects. This is a common assumption in the stock market, but it has been challenged by empirical studies that show no significant relation between insider buying and future stock returns (e.g., https://www.sciencedirect.com/science/article/pii/S0746646701002591).
- The article mentions GeoVax Labs as a penny stock, but it does not explain what the company does or why it is attractive to investors. A brief description of its business model and products would be helpful for readers who are unfamiliar with the company.

A more balanced and critical analysis would also consider the risks and challenges that InMed Pharmaceuticals faces in developing and commercializing its drug, such as competition from other companies, regulatory hurdles, funding issues, etc.
