Greenlight Capital mainly focuses on publicly traded corporate equities and debt offerings. Greenlight Capital’s investment strategy and philosophy takes a simpler approach than most. The firm clearly states that it mainly looks to invest in its funds using both long and short publicly listed equity securities. The firm also uses distressed debt, but only when those investments are cyclically attractive. The firm seeks out capital appreciation by buying securities that are undervalued and then selling them for a profit. It also looks to drive growth through short selling.
