问了一下ChatGPT，自己做判断， 不能想当然。

Ticker	Company	P/E (TTM)	Forward P/E	P/B Ratio
JPM	JPMorgan Chase	14.05×	15.6×	2.3–2.4×
BAC	Bank of America	13.9×	12.6×	1.2×
C	Citigroup	13.5×	11.3×	0.83×
WFC	Wells Fargo	14.6×	12.4–14.4×	1.65×
MS	Morgan Stanley	16.5×	16.2–16.8×	2.1–2.4×
GS	Goldman Sachs	16.2×	15.7×	1.98×
GOOG	Alphabet Inc. (Class C)	27.9×	21.5×	6.4×

Goog 是7雄里最最便宜的了，应该加仓。

银行forward earnings严重低估。政策放宽和经济形势大利好，看好银行。
