一篇关于古董车拍卖的文章中 With buyers more selective, owners are more reluctant to offer exceptional cars at auction. When they do, expectations can be out of step with new realities. Last month, during a bellwether series of sales in Arizona, two 1950s Jaguar D-Type racers, estimated at $12 million at RM Sotheby’s and $10 million at Gooding & Co., failed to sell. 第三行最后一个字 bellwether 字典是翻成“表示市场走向的证券、股票或公债” 在文中要怎么理解比较好呢？ 原文: https://goo.gl/gdfm3L 谢谢!!!
