Albert Einstein stated that the greatest invention of man was compounding interest. Mr. Einstein obviously never heard of a "Supercenter" discount store or Viagra. I love bargains. I love buying good companies at a discount. The two companies I'm highlighting today are both. They also helped revolutionize America: one through a new retailing model of everyday low prices, and the other through lifestyle-changing drugs. Both companies have faced bad publicity, and their stock prices reflect it. However, both companies are typical of my investment strategy: ample cash flow and manageable debt, and great growth prospects.
