He later became a prominent sports-business owner through his involvement with the Boston Red Sox and Liverpool Football Club.

Trading Methods

Henry's trading philosophy emphasized mechanical trend-following systems. Rather than relying on discretionary forecasts, his firm used predefined rules to identify market trends and manage positions across futures markets, including commodities, currencies, and financial instruments. The approach involved diversification, disciplined position sizing, and allowing profitable trends to develop while limiting losses when markets moved against a position.

Henry & Company eventually stopped managing outside client assets in 2012 after years of challenging performance and investor withdrawals.
