This podcast interviews Peter Oppenheimer, Goldman Sachs' Chief Global Equity Strategist, about his book "Any Happy Returns?" The discussion centers on Oppenheimer's four-phase equity cycle model ("despair," "hope," "growth," and "optimism") and its application to current market conditions. Oppenheimer argues that while the US market is currently in an "optimism" phase with high valuations, opportunities exist in undervalued international markets like Europe, where recent performance has surprised many. He suggests that diversification across geographies and sectors is crucial, particularly given the current concentration in US tech stocks. Listeners gain insights into cyclical market patterns and potential investment strategies based on valuation and geopolitical factors.
