从熊猫数据系列中获取最小值的日期

Get the date of a minimum value from panda data series

是否有任何(优雅的)方法来获得找到的最小值的日期,而不仅仅是股票价值?

import datetime
from pandas_datareader import data

ticker  = 'V'
start = datetime.datetime(2010, 5, 15)
end = datetime.datetime(2010, 6, 15)
stock_values = data.DataReader(ticker,
                                  start=start,
                                  end=end,
                                  data_source='yahoo')

min_close_value = stock_values['Close'].min() # 17.522499084472656
# min_close_date =

使用argmin,其中returns索引的最小值:

index_of_min_close_value = stock_values['Close'].argmin()
