I really love Jim Collins' stock series, and since I found it, have been reading and rereading as I become a little more savvy. So, for the first time ever this year, my husband and I will be maxing out both 401Ks, and personal IRAs. Most of these are held in VTSAX, or as close as we can get it depending on the funds available in our companies plans. We are young and not terribly concerned with the risk. We do have our IRAs in the target funds though, as I wanted some slight bond exposure (not much). So now, for the first time, we have some extra money to work with each month, and I am ready to open a taxable account.
My primary question is about international exposure. I have seen this question on the forums before, but still don't know how I feel about it. How much international exposure should I have(%), and would you use VGTSX or a different fund? Are there any special tax considerations I should keep in mind (besides not holding bonds in my taxable account)? I am especially interested in what your allocations are and why, to help make my own decision. What are the criticisms of the Stock Series (if any).
