通过 quantmod 批量下载财务数据

Question

R 包有一个quantmod。此外，还有一个财务数据请求。

getFinancials('GE'),

GE 是股票代码。

我想知道，我怎样才能下载一堆资产负债表（我有一个向量，比如 2000 个股票代码），然后将其导出到单独文件中的任何 SQL 数据库。

嗯，基本上我需要它在其他分析软件中使用，但找到资产负债表的综合数据库似乎是一项任务。我看到的唯一选择是通过 quantmod。

基本下载和查看如下：

library(quantmod)
getFinancials('GE')
viewFinancials(GE.f)

Answer 1

你可以这样做。

require(quantmod)
setwd("C:/Users/your_path_here/downloads")
stocks <- c("AXP","BA","CAT","CSCO","CVX","DD","DIS","GE","GS","HD","IBM","INTC","JNJ","JPM","KO","MCD","MMM","MRK","MSFT","NKE","PFE","PG","T","TRV","UNH","UTX","V","VZ","WMT","XOM")

# equityList <- read.csv("EquityList.csv", header = FALSE, stringsAsFactors = FALSE)
# names(equityList) <- c ("Ticker")

for (i in 1 : length(stocks)) {   
        temp<-getFinancials(stocks[i],src="google",auto.assign=FALSE)
        write.csv(temp$IS$A,paste(stocks[i],"_Income_Statement(Annual).csv",sep=""))
        write.csv(temp$BS$A,paste(stocks[i],"_Balance_Sheet(Annual).csv",sep=""))
        write.csv(temp$CF$A,paste(stocks[i],"_Cash_Flow(Annual).csv",sep=""))
        write.csv(temp$IS$A,paste(stocks[i],"_Income_Statement(Quarterly).csv",sep=""))
        write.csv(temp$BS$A,paste(stocks[i],"_Balance_Sheet(Quaterly).csv",sep=""))
        write.csv(temp$CF$A,paste(stocks[i],"_Cash_Flow(Quaterly).csv",sep=""))
}
