There is nothing wrong with the way you are looking at it, Dave. I was the same for many years, to my profit. Then I got to tinkering again. Is it better? I think so, but I have been wrong before. We all must do what we are comfortable with.
At one time I
wanted 'currency risk' because I thought the USD was not being managed well. Then I found out that most mutual funds are 'hedged' (by which I gather that they have eliminated currency risk).
So I wasn't getting what I thought anyway.
Today I do own a few foreign stocks (energy and pipeline stocks, businesses I have learned a little about) as ADRs, traded in the US in USD, dividends paid in USD. My only real currency risk has been working outside the US, being paid first in Canadian dollars (a very good move, by sheer accident) and later GBP (meh). Back to USD today because I was being reamed on the exchange rate by my agency.
For a long time I owned the S&P 500 in VFINX. Then I discovered 'slice-and-dice', which further broke the market down into more asset classes which led me to lose interest in large growth (completely cynical about large growth) and lean towards small cap and value and now dividend payers and dividend growth.
By the way, I don't like VTRIX either. Vanguard has played games with their international funds over the years.
I do have a few stocks and a small amount in two managed funds, but mostly index funds, just not total market index funds. Maybe I am only a little stupid?
