盈利动能下降是大秦铁路被剔出I66的主要原因。最近一周中信证券、广发证券等6家券商对公司给出了新的盈利预测,维持不变的有4家,调低预测的有2家。 The drop in profitability was the main reason that Daqin Railway was excluded from I66. In the most recent week, six brokerages such as CITIC Securities and GF Securities gave new earnings forecasts to the company, with four remained unchanged and two lowered their forecasts.
