查找股票所属的行业

Question

给定标准普尔500指数中的股票，我如何使用R包或其他来源找到每只股票属于哪个板块，例如金融、能源……？

Answer 1

“部门”这个术语本身就是一个模棱两可的术语。一个数据提供商所称的“消费者服务”可能会被另一个数据提供商称为“餐馆”。也就是说，TTR提供了一个名为stockSymbols的函数，该函数从纳斯达克返回约6400 NMS股票的一些信息，包括行业。

library(TTR)
ss <- stockSymbols()

#Fetching NYSE symbols...
head(ss)

如果你只是想要标准普尔500指数中的股票，你可以欺骗并使用SPY持有的股票(或者你可以在很多地方找到标准普尔500指数的股票，包括标准普尔网站)。
