Give me a museum and I'll fill it. (Picasso) Give me a forum ...
Or they don't wish to share on this site, when others are doing better. Nothing wrong with that, but also part of human behavior.
A big part of the overstating of performance is that many folks don't include everything in the calculation. Perhaps one brokerage has a nifty tool which gives daily performance reports, so they use that. They omit cash stashes, bux they tied up in an annuity, another brokerage which is holding some lower performing funds, etc.
I do agree, it seems strange to hear so many reports of outperforming the market on a forum which largely supports broad based index funds which reflect the markets.
It's all interesting to read, but take the reports with a grain of salt unless the holdings generating the well above market results are clearly defined.
