Procter & Gamble is the company behind Tide detergent, Crest toothpaste, Pampers diapers, Bounty paper towels, Charmin toilet paper, and a bevy of health, beauty, baby, and cleaning products. Best of all, a lot of what P&G sells are basic-needs goods. We need to brush our teeth, wash our clothes, and buy toilet paper regardless of whether the U.S. economy is growing at 5% per year or contracting at 3% per year. It means the demand for P&G's products doesn't change very much, and if anything, it tends to rise with a growing population. Ultimately, Procter & Gamble has little incentive to discount its products, leading to strong pricing power and profits.
