Looking for a Excel Expert to help finish a project. Three things need to be done. 1. Auto update the database from Yahoo Finance. 2. Calculate the correct rate of return given the dates. (It mostly works now, but the latest date does not adjust when the recent date is adjusted). 3. While this is not vital to the project, I need to rebalance the portfolio over the time period discussed. Contact me for more questions. I will also send you the spreadsheet we are talking about.
