Walter Kraslawsky said: Thanks Sherlock. I especially appreciate the yahoo link and will save it for future research on varied other funds. And, yes, my comparisons of varied fund percentages led me to drop my S&P500 investments in favor of NASDAQ-100 investments. But otherwise I failed to be clear that I am trying to calculate, not imagine, what my real return would have been. It’s part of my process for calibrating the spreadsheet formulas in my investment model.
