Pandas'corrwith与SPY合作得很好,但^ GSPC不行。 有谁能够帮我 ?提前谢谢。
import pandas.io.data as web
import numpy as np
import pandas as pd
import matplotlib as mpl
import matplotlib.pyplot as plt
import csv
Symbol = ['^GSPC','SPY','XLK','XLV','XLY','XLP','XLE','XLF','XLI','XLB','XLU']
STOCK = web.DataReader(name=Symbol,data_source='yahoo',start='2000-1-1',end='2009-3-1')
STOCK['PercentA'] = np.round(np.log(STOCK['Adj Close']/STOCK['Adj Close'].shift(1)),3)
### OK wiht SPY, but not OK wiht ^GSPC
STOCKCORR = np.round(STOCK['PercentA'].corrwith(STOCK['PercentA'].^GSPC),3)
StockNan = STOCKCORR[~STOCKCORR.isnull()]
StockOrder = StockNan.order().iloc[::-1]
StockRows = StockOrder.iloc[:20]
print StockRows
