when i put in ACAD, I posted every purchase I've made for the last 9 1/2 years. I've made about 18 purchases ove r that time between 2016 and 2025. When I inputted all of those lots, the annualized gains states I've averaged 19.47% as of 5/16/25. I don't think that is correct. What formula do you use to calculate this? I heard using the extended internal rate of return is is best for multiple lots over a period of time and you haven't sold any shares.
