Hello,

I have a product feature request inspired by Bloomberg’s COMP function.

Bloomberg allows users to compare up to five stocks, ETFs, or indices over a selected period. For example, I can compare QQQ with AAPL over the past two years. Each security is rebased to 100 at the beginning of the period, making their relative percentage performance immediately visible on a single chart. The output also displays each security’s cumulative and annualized return.

Koyfin currently allows me to place multiple time series on the same chart using either separate or shared axes. However, I have not found a way to rebase all the securities to the same starting value or display them on a normalized percentage-performance basis. This makes it harder to see at a glance which security performed best over the selected period.

It would be very useful to have a comparison feature that:

Rebases each series to 100 at the beginning of the selected period

Shows cumulative percentage returns

Shows annualized returns

Ideally allows users to choose between price returns and total returns

Another feature would be to allow versus a portfolio and benchmark comparisons.

Thank you for considering it.
