Icahn Enterprises

In later years Icahn extended his corporate arguments to macro warnings about credit markets and what he called euphoria in high-yield debt, publishing a series of public letters and video statements in 2015-2016 cautioning that illiquid index products had made corporate bonds falsely cheap to trade. Whatever the eventual verdict on those calls, they showed the same instinct that defined his stock campaigns: distrust consensus, and position against it loudly enough to be forced to defend the position.

In his 2013 letter to Icahn Enterprises holders, Icahn laid out what he called the country's governance problem: boards chosen by chief executives, compensation consultants rewarding mediocrity, and a system he argued rewarded insiders over owners. The letter made the case that activist investing was not a disruption of good governance but a substitute for its absence.

The letter also updated holders on the portfolio approach of Icahn Enterprises — concentrated positions in companies he judged cheap, activist engagement to close the gap, and hedging of the broad market he described as overpriced. He framed the vehicle explicitly as a way for ordinary investors to access activism at scale.
