一直困扰我的一个疑问？

$特斯拉(TSLA)$$英伟达(NVDA)$ $京东(JD)$ $Advanced Micro Devices Inc.(AMD)$ 美国的投行为什么有权对股票评级呢？人们为什么都喜欢听信评级呢？投行自己都有权买股票，为什么还有权评级股票？如果我是投行我提前买入一只股票，然后过几天发布上调评级不是躺着赚钱？卖空亦然，有谁能给我解释解释啊？

评级的是研究部门，买卖股票的是资产管理部门
- SummerRest回复Fany:
  分sell side跟buy side，你经常听到的市场上高盛啊，摩根啊什么的新闻，多是sell side发出的声音，它们不买卖股票，只给投资建议，卖观点。有另一帮人，手里有钱，做买卖股票生意的，他们需要sell side强大的研究支持买卖，此所谓buy side，这帮人属于闷声赚（亏）大钱的，当然不会整天瞎嚷嚷.在混业经营的条件下，一家大投行既有sell side部门，也有buy side部门
- Fany:
  求长文科普。

法规要求隔离……实际上呢
- 路人丁:
  实际上也是这样，你被抓一次罚到你怀疑人生。风险收益比太不值得

法规要求要隔离，and 你和投行部可以看到研报的时间是一样的。至于说可信度，这个就是每个机构自己积累的了。

就像前几天软银增持英伟达一样，增持完了告诉大家，这家不错，我买了，你们看着办吧！

如果投行按楼主说的干，以后再出评级就没人
