In this episode of the Planet MicroCap Podcast, I spoke with Sean Westropp, Founder and Portfolio Manager at Deep Sail Capital, to dig into his four pillars framework for finding exceptional growth companies - and why running both sides of the book makes him a sharper long investor.
We break down how he balances quality, management, growth prospects, and valuation across a portfolio split between emerging and established growth names, why outstanding management is the one pillar he refuses to compromise on, and what the 2022 drawdown permanently changed about how he manages a portfolio. We also get into his criteria for shorting in microcap, why defense has been his best-performing sector, and the hard lessons on headline risk.
