9月18日，巴菲特指數（滬深300市值/GDP）略微回升至92.11%，不過暫時未打破近兩個月震盪下行狀態。股債性價比指標——滬深300指數股權風險溢價（ERP）爲5.75%，較前一日刷新的逾13個月新高略有回落，依然處於偏高位置；從大週期來看該指標從過去四年波動區間下端逐步向中間區域靠近，暗示目前股市相對國債收益的吸引力有所上升，回到了中性偏高水平。 -------- 注：1、巴菲特指數是通過將股市總市值和GDP來比較，判斷目前股市是否高估，通常70-100%爲正常估值，低於該區間爲低估，高於該區間爲高估。 2、滬深300指數風險溢價（ERP）主要對比滬深300收益和國債收益率，統計近10年數據可以發現該指標和股指有明顯反向關係，每次股市都處於底部區域時，風險溢價均超過6%，也就是當ERP≥6%，股市有投資性價比，而當ERP≤4%時，則股市往往接近或處於階段性高點，投資性價比低甚至要小心回調風險。
