Phillips 66 (NYSE:PSX) has become one of my favorite stocks to cover. In general, I have always liked covering the company due to its significant footprint in the refinery and chemical industries. However, in my most recent article, published on December 5, I covered a major new development, including an activist investor, going with the title "60% Gains Plus Dividends With Phillips 66 If Elliott Is Right." Since my November article on Phillips 66, activist giant Elliott Investment Management has entered the scene with a $1 billion stake and a bold letter to the board.
