很多人对大选前三个月(约63个交易日)股市📉执政党(Trump)输,在野党(Biden)赢这个法则不信.没关系,Bloomberg的回测表示此法则准确率高达87%! Since 1928, a positive return in the S&P 500 over the three month period before the election tended to point to a victory by the incumbent party, while a negative return favored the challenger. The “indicator” has predicted 20 of the past 23 elections. Its track record since 1984 has been pristine.
