The Stock Is Up Almost 56,000% and Is Still a Buy

O'Reilly Automotive has been a huge success story since its founding in 1957. No imagination is required for such a lucrative outcome if you invested $10,000 in O'Reilly Automotive (NASDAQ: ORLY) at its initial public offering in April 1993. If you're like me, you can't think about O'Reilly Automotive without hearing the lyrics to its jingle in your head, "Oh, oh, oh, O'Reilly... auto parts!" The auto parts retailer's growth through the years warrants a few "ohs."
