Conclusion two:Analys evaluated securities each month,which is overstating its estimates because the price momentum effect in stock market 解析没有看懂，请问conclusion two为什么是正确的？
conclusion two 和one其实讲的是同一件事儿。股票市场价格有momentum effect，那就是涨了持续涨，跌了会持续跌。那么分析师知道有momentum之后，他看到股票开始涨了，就会预测接下来一段时间都会涨，就不是independent decision。所以 overstates its strategy breadth
