Brian Stoffel pivoted from teaching to investing. His investing track record will beat many best professional fund managers in the world. His stock portfolio is 10 times in 10 years. In the discussion, Brian talks about 1) How he pivoted from teaching to investing 2) his investing framework and thinking 3) His lessons on the way 4) His advice for fellow investors Brian’s Portfolio details are also attached below. Brian is deeply influenced by David Gardner's investment philosophy and Nassim Nicholas Taleb's life’s philosophy. He believes that even if you lose 9 out of 10 times and win big in one…you could still have phenomenal returns. His best investment has been Shopify which he bought in 43 dollars and now it's 1600 USD plus. This is insane 40 times gain. Brian likes to invest in companies that are anti-fragile. You can find his anti-fragile framework here (gumroad.com/l/zWXye) His investments are likely to be in companies a) Mission drive i..e they are driven by larger objectives, more than money b) the businesses have wide moat c) it's driven by people who every morning think that what can they do better to further the mission. Brian doesn’t focus on the stock. He focuses on the business. He thinks like an owner. Moat of the company, optionality in the company, and mission are critical factors of an antifragile company. Holding such companies with patience can be hugely rewarding. One of the reasons for investing and remaining invested in Shopify was Tobias Lutke’s commitment to his mission. The company’s willingness to do something great created new projects and optionality which no wall street analyst could have imagined. If Brian starts investing fresh today again…he would start with investing in companies that he is aware of e.g. Apple, Axon. And as a seasoned investor, if he gets a fresh infusion of 1 million USD, he would look for smaller companies like Riskified, Semrush, Pubmatic, and AXON enterprises. These companies meet the criteria in the anti-fragile framework.
