This is a question that’s been on my mind for a while, partially out of curiosity and also because it’s been raised by readers a few times: Suppose you didn’t get the “memo” on passive investing early enough in your life and you now have some high-expense-ratio funds in our portfolio. So, is it too late to switch to a low-cost fund now? Maybe you’re lucky and your funds are actively-managed and they actually beat the broad index reliably. Good for you, but more often than not people are unhappy with the performance of their high-fee funds and like to switch to a low-fee, passively-managed index mutual fund at Fidelity, Schwab or Vanguard. Or move to one of the many index ETFs. Fees will be in the low single-digit basis points, around 0% to 0.015% for some of the Fidelity index funds and around 0.035% for the “Admiral Shares” Vanguard funds. Of course, if this is a fund in a tax-advantaged account where you can just switch between funds without any tax consequences you should just do so if you have that option. But the story gets a lot more complicated in a taxable account! We now have to weigh the pros and cons of switching to a low-cost fund:
Pro: You get rid of that “stinker” mutual fund and replace it with a low-fee, or even zero-fee index fund and eliminate the drag from the high expense ratio. We could be talking about a 0.5% difference in fees and maybe as much as 1.0 or 1.5%. And that’s every year! This can accumulate to a very large pile of cash over time!
Cons: You may have to realize capital gains today. There is a tax inefficiency from having to realize capital gains before you actually need the money in retirement. And this inefficiency takes two forms:
1) for most of you, there’s a good chance that marginal tax rates will be lower in the future, especially in retirement. Your high income right now might put you into a high marginal tax bracket (both Federal and State), while in retirement you might face much lower (or potentially zero) marginal rates. It’s best to defer capital gains until then!
2) even if your future projected tax rate is the same, there’s a potential inefficiency due to realizing capital gains twice; once today when switching to the new fund and once in the future when liquidating that fund in retirement, thus compounding the drag from taxes. It’s best to defer capital gains and pay taxes only once in retirement.
So, depending on how much in built-in capital gains you have right now, how much you can lower your expense ratio and what your current and projected future tax rates are, it may be optimal or suboptimal to dump that high-expense fund. In other words, it is the choice between two evils: The one evil is the drag from the high expense ratio and the other is the drag from tax inefficiency. Which one outweighs the other? Hard to tell, unless you put some numbers in a spreadsheet and do a proper “horse race.” And that’s what we do here today. Let’s take a look…
