Activist investing is back. On this week's episode of Merryn Talks Money, Merryn Somerset Webb speaks with Joe Bauernfreund, chief executive of Asset Value Investors, about buying quality companies at deep discounts—and actively forcing a catalyst.

The conversation spans Japan’s ongoing governance-driven rerating, South Korea’s push to be the new Japan and moneymaking special situations from Mitsubishi Logistics to News Corp. They also unpack why AVI tilts away from the US, how private-equity trusts and buybacks can unlock value and what the future might be for the UK’s ailing investment trust industry.
