I am trying to use the Pipeline framework to calculate correlations between all assets in my universe and a single Equity that I can choose. Ideally, I would like to input an asset_id representing my selected Equity and then return a Pipeline result with a column of values representing all correlations. Below, I have chosen SPY as my single Equity (for now). However, I keep getting errors.
Any ideas on what I'm doing wrong? Thanks very much!
