Paul Black is Co-CEO and portfolio manager at WCM Investment Management, a $26 billion manager of global equities that he joined when it was a $200 million boutique in 1989.  With so much of the institutional world, including my own training, focused on value investing, I was pleasantly surprised to learn about a large, high performing growth stock manager located in a non-descript building in Laguna Beach, California.
 Our conversation starts with Paul's trial-by-fire entry into the business and turns to growth stock investing, including defining a great growth company, searching for widening moats, assessing a culture tied to competitive advantage, creating a positive culture, learning from mistakes, identifying tailwinds, and protecting the downside.
 Paul embodies the principals he preaches and offers some tasty food for thought.
