Gyroscopic Investing

My 401(k) is getting rid of one of my favorite funds--VITSX. It's being replaced with VIIIX, which has a slightly lower ER but tracks the S&P 500 rather than the whole stock market. I rather prefer the total market funds, so I'm considering switching it out for SCHB, Schwab's total market fund. This is the only commission-free total market ETF I have available in the 401(k). Its correlation with Vanguard's total market fund is excellent, its ER is very low (0.06), and the prospectus doesn't reveal any shenanigans, but it doesn't have a lot of history. The fund is only barely 3 years old.

Do folks think I go with the younger total market Schwab fund, or the more established S&P500 Vanguard fund?

The Schwab fund will be fine. It's one we list in the upcoming book as well. But the Vanguard fund is fine as well. That's odd that they would get rid of the total market for the S&P 500 though.

Thanks craigr, that makes me feel more confident. I'm also happy to switch it out since it makes the total asset allocation across all my PPs a little bit less Vanguard-heavy.
