Sector Performance Unknown

Hi Team, I am starting to like the product, would like to understand more of Sectore Performance and Sector Diversificaation, My portfolio has this as "Unknown" for the major part, and I believe this is because those are ETFs See if you can get from the %age of holdings from ETFs and get them to display here, I know things are easier said than done, just my 2 cents on feature request. Thanks Ravi
