Corbus Pharmaceuticals: 46% Stake Held by Retail Investors Influencing Management
- Retail Influence: Corbus Pharmaceuticals has 46% of its shares held by retail investors, indicating significant influence over management and strategic decisions, which could drive the company towards more public-interest-aligned directions.
- Institutional Participation: Institutional investors own 23% of the company, which brings credibility from professional investors but also raises the risk of a 'crowded trade' in a company lacking a growth history.
- Hedge Fund Role: Hedge funds hold 24% of the shares and may attempt to influence management to create short-term value, particularly driven by major shareholders like Cormorant Asset Management and OrbiMed Advisors.
- Insider Ownership: Insiders own less than 1% of the company, which may challenge other shareholders in holding management accountable for decisions, especially given the market capitalization of only $156 million.
