Hello,
My last 3 acquisitions integrated into Portfolio are giving me extravagant IRRs as shown in the attached screenshot. These purchases were made on March 3 and 4 this week.
Yes, the percentage is p.a. (per annum) and you purchased only a couple of days ago. If the stocks increased a lot those numbers make totally sense, because p.a. calculates that this increase will go on for the whole rest of the year.
So over time it is likely, that those percentage numbers will come down a lot.
