For our penultimate season one episode of Fill the Gap, we are very fortunate to feature an in-depth conversation with Irusha Peiris, CMT.  Not only has Irusha been practicing the CAN SLIM methodology made famous by William J. O'Neil in his bestselling book, How to Make Money in Stocks, for over two decades; he has also been working within the O'Neil companies since 2009. As a CMT charterholder, portfolio manager at O'Neil Global Advisors, weekly contributor on IBD's must-listen weekly podcast Investing with IBD, and former Director for O'Neil's excellent Market Smith web-based equity research product, Irusha brings a wealth of experience and perspective to this highly informative discussion. Our conversation spans topics that range from staying focused on picking "game-changing stocks" to the importance of patience and discipline; from always staying humble, to how to manage the pesky mental challenge of constant portfolio drawdowns, and so much more.  As a life sciences student in Boston, Irusha was given the fateful advice to only get into medicine if he was 100% sure it was what he wanted. Certain that he wasn't that certain, he decided to shift his focus to the stock market, where he truly found his passion - and we are grateful that he did.  To better understand the concepts covered and market commentary included in this episode, we recommend reviewing the supplemental resources available on the CMT Association website using this link: go.cmtassociation.org/ftge11.
