Passive investing was designed to track the market, not shape it. But as Merryn Somerset Webb and John Stepek explore in the second episode of The Portfolio Reset, the enormous growth of passive investing has changed the market it was built to follow, just as some of the world’s most valuable companies are staying private for longer.

Using SpaceX as an example, they examine the changing relationship between public and private markets and why no investment is truly passive — someone is always making a decision somewhere in the process. As passive flows grow powerful enough to move markets, Merryn and John explain why investors should make sure they’re making active decisions in pursuit of their own financial goals, rather than leaving those decisions in the hands of strangers.

After years of being overshadowed by US megacaps and the artificial intelligence boom, could smaller companies finally be ready for a comeback? Merryn Somerset Webb speaks with Downing fund manager Simon Evan-Cook and Odyssean Capital’s Stuart Widdowson about why small caps remain unusually cheap, what could bring investors back — and whether small-cap value could become the ultimate anti-AI trade.
