First time poster here. I have thoroughly enjoyed lurking throughout the forum as my wife and I embark to shed layers of ridiculousness from our lifestyle. My first draw to MMM was a concise article on index investing and the reviews on investment theory, etc. I've got a specific question:
I am new to the bogleheads / Vanguard style of index investing, but am starting to buy in. I am currently accumulating in my 401k at work, which obviously has limited options. My only equity fund choices with even reasonable expense ratios include a fund that tracks the MSCI ACWI IMI index (expense ratio of 0.06% -Sweet!) versus a Russell 3000 tracking fund (expense of 0.54 - WTF?!?) that would be balanced internationally by DODFX (0.64% ER). My hesitation to using the MSCI fund is the lack of information I have found on available ETF strategies that incorporate its use, and few funds that track it.
What am I missing here, as far as reasons to avoid it as my core 401k holding? Any fundamentals, as far as re-balancing goes, that would be 'off' due to holding a 'world stock' type all-in-one fund? Anyone use an MSCI ACWI fund as a core holding?
By the way - there are Target Date funds available, but I am currently looking to be 100% in equities, and even the longest horizon does not offer less than 5% in bonds / cash. We are maxing out Roths already, and I want to take full advantage of my tax advantaged options.
