I am trying to create a dividend portfolio with the help of QuantConnect. It is my understanding that I find fundamentals in the FineFundamental data structure, right? Looking there I find for example in the EarningReports for ‘HWM’ (Howmet Aerospace Inc) from 10-31-2022:

EarningReports.DividendPerShare.ThreeMonths = 0.02
EarningReports.DividendPerShare.SixMonths = 0.04
EarningReports.DividendPerShare.NineMonths = 0.06
EarningReports.DividendPerShare.TwelveMonths = 0.04

My goal is to get the annual yield in %.

My questions are:

Am I looking at the right place?
If so, why is the twelve month value inconsistent with the other values?
What is the best way to get a historical annual % dividend yield?

Thanks,
