Hi Dan,
Hi Dan,
Thanks for your support.
I really appreciate your attention.
Please see attached a very sinple notebook in order to show SPY returns in several period
Runing this simple code with returns, i can see that results are not the same than morningates or ameritrade websites.
These are the links in order to check.
http://performance.morningstar.com/funds/etf/total-returns.action?t=SPY Note: (Please click on monthly tab)
https://research.tdameritrade.com/grid/public/etfs/profile/performanceBuffer.asp?symbol=SPY&fromPage=performanceBuffer&display=&fromSearch=true
These links shows exactly the same returns metrics for SPY but for any reason i cant see the same in Returns from quantopian.
Also, the close price from "USEquitypricing.close.latest" match with June 05, not for June 08 close. Today is June 09.
My apologies if it has a very basic answer.
Thanks again for your support!
