The formula that is in the Cumulative Return cell that is showing -0.09% is this.
=IF(ISBLANK(J2), 1, (1+J2))*IF(ISBLANK(J3), 1, (1+J3))*IF(ISBLANK(J4), 1, (1+J4))-1
How can I make it so that this automatically performs what I want when I insert new rows into Return. Right now I am having to keep adding IF(ISBLANK(J#), 1, (1+J#)) into the formula manually with incrementing # number.
