I joined Jess Maguire on ABC Statewide Drive to discuss how the rise of passive investing is changing the sharemarket, with index funds increasingly pushing money into the biggest companies regardless of valuation. Using SpaceX as an example, we explored how speculative companies can attract enormous valuations during periods of market optimism, and why that may not last forever. We also looked at what this means for Australians, many of whom may have exposure to these trends through their superannuation.
