Willis Towers Watson Public Limited Company (NASDAQ:WTW) is not a famous company and is often favored by value investors who seek long-term growth. Klarman, one of the best in the business at value investing, has some advice for those trying to replicate his success. In his book Margin of Safety, Klarman notes that value investing by its very nature is contrarian. Per the billionaire, out-of-favor securities may be undervalued; popular securities almost never are. He adds that what the herd is buying is, by definition, in favor. Securities in favor have already been bid up in price on the basis of optimistic expectations and are unlikely to represent good value that has been overlooked, he underlines.
