H @Raj Sachdeva That link seems to work for me: https://www.bionicturtle.com/forum/threads/market-portfolio-and-derivative-of- weight.9919/#post-45560 i.e.,
@Sergio Guerrero and @QuantMan2318 Sure enough, amazing mathematica solves it (see below). Almost as amazing, I entered the solution into Excel and it seems to work perfectly given a few various test values (I got that formula in on the first try, i thought for sure i'd muck it up...). Tomorrow I'll get it into properly formatted into our learning spreadsheet and share it back for you to see. Thanks for asking Sergio, I am excited to have an analytical solution right in the spreadsheet, who knew!!!
