Carl Celian Icahn, is an entrepreneur and investor of Jewish origin, founder of Icahn Enterprises, a flotilla of companies based in New York. He obtained a degree in philosophy at Princeton and then studied medicine, but retired to join the army. His eagle eye to see business opportunities with the purchase of cheap stocks of maldened companies, which he then refloat with new methods, has been the key to his success. But it has also invested in high-profile companies such as Philips Petroleum, Viacom, RJR Nabisco, Neflix, Herbalife and Time Warner.
Icahn’s only shareholding in a company serves as a business guide to Wall Street investors. For example, in 2013 when it revealed the purchase of $ 1 billion in shares at Apple, the market immediately reacted to the upside. During Donald Trump’s election campaign, the president said he would like to have Icahn as secretary of the Treasury and he said he would gladly accept but has not yet happened.
