Gladstone Investment Corporation (NASDAQ: GAIN) is a publicly traded business development company, meaning it is collectively owned by a diverse group of institutional investors, mutual funds, and individual retail shareholders rather than a single private entity. Institutional asset managers, wealth advisory firms, and insiders—including founder David Gladstone and executive management team members—hold various blocks of common and preferred stock. These shares are actively bought and sold on the NASDAQ global select market, resulting in a fluid ownership structure that shifts daily based on open-market transactions.
