There are many strategies to invest for retirement, but if they include loading up on stocks in your old age, they’re dangerous, says Raoul Pal, former hedge fund manager and chief executive officer and co-founder of financial media company Real Vision. In an effort to assist Americans in preparing properly for their retirement, Pal and his company released a two-week campaign of retirement-related videos, which focus on different aspects of the investment process. Some episodes highlight the global pension industry, while others draw attention to how high investment fees and behavioral traps can hurt investors.
