Charlie Aitken has a simple investment philosophy: Build a concentrated portfolio of the world's best companies in structural growth sectors. And for this week’s Rules of Investing podcast, I had the rare opportunity to sit down with Charlie for 46 minutes to hear how this translates into practice.

While the market grows anxious about the rapidly metastasising trade war, Charlie explained in our discussion how he sees it as a ‘tremendous opportunity’ to grow exposure to world-leading companies, and went on to nominate four such stocks right in the firing line right now.

I really enjoyed recording this podcast in which we covered a great deal of other ground, including his transition into funds management, advice to his younger self, and why it’s ‘Australia for income - and global for growth’.
