Things you can see, touch, feel, and/or use for which there is a price. Some are old standbys (gold might fit the bill), some are modern necessities (oil, natural gas, and other energy commodities would fall into this category) and some are things you’d never think could be traded (like pork bellies, from which we get bacon). BTW, investing in, say, pork bellies doesn’t mean you actually get that object (ew), but you own stock in it that’s traded on one of about a dozen special exchanges for commodities like the Chicago Mercantile Exchange and the New York Mercantile Exchange.
