“Our stock selection performs best when any optimism surrounding the improving fundamentals of companies we’re watching are confirmed by the actions of management. That can come in several forms, including active share buybacks (indicating management believes the stock is undervalued), insider buying (a sign that executive leaders believe the stock is a good value and willing to put their own money on the line), and growing dividends (a sign of management’s confidence in their future profits and cash flow). Currently, roughly one-third of our holdings in the Strategy have insider buying; 84% of our companies are in active buyback mode; and 61% have increased their dividends in the past year.
