Kitces' work is interesting and he makes some good points. Turnover is unpleasant in taxable funds, as my legacy T Rowe Price funds proved the last couple of years. Taxable bond yields are so low, they might as well be tax exempt.
The problem with the Vanguard tax managed balanced fund is its dependence on tech - Google, Facebook, Microsoft, Apple, Amazon, etc. Same with the S&P 500 fund. My question was if there was a tax managed balanced fund that did not depend so heavily on tech. Managers focused on taxes like tech because historically it has provide growth without those pesky taxable dividends. However, tech is very cyclical and prone to overvaluation when times are good, as they are now.
I suppose I could buy a municipal bond fund or ETF and look for an equity fund that happens to be tax efficient but not overweighted in tech and accomplish the objective. A lot of work I would rather not do.
I don't own bonds or bond funds, in part because I was taught that bond risk is misunderstood and underestimated by most people. In addition, in a market where everything is overpriced and everyone is chasing yield, bonds and equities may be correlated and bonds more dangerous. I have to take my bond medicine hidden in places like Vanguard's Wellington (in an IRA), where I can hope the managers are more astute at analyzing bond risk than most people.
