Starbucks stock has gained 16,376% since it went public June 26, 1992, at $17 per share. Clearly, it's one of the all-time great American retail success stories and CEO Howard Schultz has a lot to do with that, but if you think Starbucks stock doesn't have more in the tank -- think again. Starbucks stock hit a high of $95.23 just before the last time it split on April 9, 2015.
