That got me thinking about which companies benefit from our desire for recreation. I found that the recreational products industry has several companies that attract the attention of the guru strategies I follow. Some are marine-oriented, some are toymakers and then there's that icon of the open road, Harley-Davidson ( HDI). Each of these names stacks up well against the strategy based on the writings of Peter Lynch. The Lynch strategy looks, in part, at the price-to-earnings ratio relative to growth, which is a measurement of how reasonable the price is. A low P/E/G suggests the price might be a bargain. The other strategy I reference is based on Warren Buffett's methodology, which as I understand it, looks for companies with a competitive advantage, predictable earnings increases, conservative financing and a return on equity of at least 15%, among other criteria.
