财务的自我修养,微信公众号:机智出品(jizhjchupin),文中各类数据文件均可于公众号内下载
现在整个市场上有近7000支基金产品,股票型、混合型、债券型、QDII、ETF、LOF等各种类型。近一年有涨了50%,也有跌幅超过30%的。面对这么多基金,我们该如何选出适合自己的赚钱的基金?
本次介绍数据获取过程,请看下文......(对获取数据过程无兴趣者,可直接下载数据)

一、获取基金列表:
下面我们用Python爬取全场所有基金的代码名称等。文件下载:fundlist.xlsx,密码公众号内回复fundlist可得。

二、获取6000多基金近两年数据:
用刚才获得的基金代码列表爬取历史数据,并存到MySQL里面。有差不多251万多条数据。全部基金近两年行情数据CSV文件下载:fund.zip,密码公众号内回复fundzip可得。

三、251万基金数据分析,及选基策略:
未完待续......(挖个坑下次写)
希望解决下列问题吧
1、各类型基金收益排名
2、基金投资策略
3、定投选星期几收益更高?
4、一个月买一次还是一个星期买一次好?
5、基金该不该止盈?
