John W. Henry
The firm's management methods make mechanical, non-discretionary trading decisions in response to systematic determinations of reversals in each market's direction, with the explicit intention of precluding not only human emotion, but also any subjective evaluation of factors outside of price behavior (such as the so-called fundamentals), to trigger each decision to be long or short each market, or not. On November 9, 2012, John W. Henry &amp; Co., the financial trading firm owned by the Red Sox owner, informed clients it would stop managing their assets on December 31, 2012.
