I've had a working model of a financial graph model based on the blog post: https://blog.wolfram.com/2012/06/01/graph-theory-and-finance-in-mathematica/
However, since upgrading to 12.0 I'm running into an issue when trying to transpose the time series. I'm not sure why this is happening. Can anyone else validate or advise on what has changed?
port = {"AADEX","FGCKX","WFDSX"};
portRe=FinancialData[#,"Return",{{2019,1,1},{2019,5,03}},"Value"]&/@port;
portRe=PadLeft[portRe]
portco=Correlation[Transpose[portRe]];
Thanks
