Talk:Approximating total stock market

I see that these percentages havent been updated in 4 years. Do we think they are still accurate? --Hoppy08520 12:12, 4 August 2012 (CDT)

I checked one in 2010 (see footnote), but that's about it. --LadyGeek 14:13, 4 August 2012 (CDT)

"It would be good to offer a suggestion on the closest allocation if you only have a large-cap fund (S&amp;P 500) and only *one* of a small-cap or mid-cap fund ... this is often unfortunately the case in 401(k) plans."

Any thoughts?

Since the S&P 500 is roughly 72% of the total market, it's not possible to allocate anything other than 25% to a single small-cap or mid-cap fund. The better approach is to consider the total portfolio and try to accommodate the difference in another account.

Otherwise, choose whichever fund is available for the remaining 28% (either small-cap or mid-cap), as this is the best you can do.

The intent of this page is to show how to approximate the total stock market. Not having sufficient fund choices is out-of-scope here and is best discussed in the Bogleheads' forum. Additional insight can be found here: How to build a lazy portfolio --LadyGeek 21:32, 3 January 2014 (CST)
