Gotham Partners Management Co. LLC
Gotham Partners Management Co. LLC Investment ManagersFinance Pershing Square Capital Management is a concentrated, research-intensive, fundamental value investor in the public markets. Their funds’ investment objectives are to preserve capital and to seek maximum, long-term capital appreciation commensurate with reasonable risk. The firm defines risk as the probability of a permanent loss of capital, rather than price volatility. In their value approach to investing, Pershing Square seeks to identify and invest in long and short investment opportunities they believe exhibit significant valuation discrepancies between current trading prices and intrinsic business (or net asset) value, often with a catalyst for value recognition. They focus on deeply undervalued or overvalued securities due to their belief that a well-priced purchase or short sale is often the most important determinant of the success of an investment. In addition, Pershing Square believes that the acquisition of a portfolio of investments, when acquired at a large discount to intrinsic value, provides a margin of safety that can mitigate the likelihood of an overall permanent loss of each fund’s capital. Pershing Square is an activist firm and is included in the SharkWatch50 as one the 50 most prominent activist investors. | Finance |
