Buffett indicator (CSI 300 market cap/GDP) fell to 92.59% on Aug 13. CSI 300
equity risk premium (ERP) was 5.26%, oscillating around 5.2% since July and
sitting at the lower end of its range since Oct 2024, suggesting the market’s
yield advantage over government bonds is modest. Historical thresholds: Buffett
indicator 70–100% is typically viewed as normal (below = undervalued; above =
overvalued). Over a 10-year sample the CSI 300 ERP is inversely correlated with
the index; ERP ≥6% has coincided with market lows and stronger investment value,
while ERP ≤4% has typically coincided with cyclical highs and reduced investment
appeal, raising pullback risk.
