“Still, the fourth quarter of midterm-election years has produced an average gain of 7 percent and has been positive 84 percent of the time since 1950.”Lerner said that rising interest rates posed the biggest risk to the upward trend.
他说：“尽管如此，总的来看，证据的权重表明，这轮牛市仍有更多上涨潜力。”
“Still, on balance, the weight of the evidence suggests this bull market still has more upside potential,” he said.
