The following video is part of our "Motley Fool Conversations" series, in which, Tom Gardner, Motley Fool CEO, stops by to discuss topics around the investing world.

In today's edition, Tom offers his suggestions on how to build a portfolio that will set investors up not for the next year, but the next decade. The average U.S. investor now holds stocks for only 130 days. Tom believes that the market rewards investors for finding great companies and holding investments over the long term instead of trading in and out of stocks with little knowledge of the underlying companies. Tom offers up four companies he believes are built for the long run, including Lancaster Colony, J&J Snack Foods, and National Presto. Finally, for investors looking for a stable large cap that's a proven outperformer, Tom suggests taking a look at Philip Morris.
