Agree, I should do some research about them. Except Elite Trader, can you please provide some suggestions that I can learn about them effectively and quickly?
You can compare SWPPX vs. VFINX here, just type SWPPX vs. VFINX and you'll get your full comparison. What I like about Schwab funds is in some cases, they are more tax efficient (as demonstrated by the lower tax cost ratio). Also shooting for rock-bottom as far as the cost. But definitely, a lot of catch up to do with Vanguard...
Here is the "after tax" returns directly from Vanguard website.
Tax cost ratio depends upon investor's own tax brackets. I would also ignore all third party websites, instead it is better directly go to fund websites and read prospectus.
Even M* does not have right information about qualified dividends.
Vanguard has the advantage because same fund can be mutual fund or ETF. That way they can tax manage efficiently. No other fund (as far as i know) has similar arrangement.
