Callum Thomas — Chart of the Week: The Speculation Generation

"A generational shift in investing has occurred." US households are running the highest allocation to equities on record — and, as a result, the stock market is trading at record-high valuations.

One-line take: A single-chart macro note — no specific tickers named (the S&P 500 / US households appear only as the macro aggregate the data is drawn from). Thomas's chart shows US households at the highest equity allocation on record, which mechanically pairs with record-high market valuations. He frames it as a once-in-a-generation shift in market structure — understandable given the >10x rally off the March 2009 low, strong earnings, tech disruption, low rates and passive flows, but not normal. Confidence is near record highs, earnings optimism is euphoric, defensives and diversifiers are shunned, and social-media chatter is saturated with greed: "the speculation generation." His posture is deliberately non-judgmental — not good or bad, just: what is the lay of the land, what does the data say, what are the pragmatic next steps?
