No it's not a taxable account.
As a spin on my original question, instead of already owning a position suppose I (or you) were looking to add to an asset allocation and you saw two funds in the same sector that have different investment styles, in this case one market cap weighted vs equal weighting. How would you choose between them. Would you simply go with the one that has the lower ER or would you look at total return over the past X years as well. Past performance...etc. but that doesn't mean it will do worse going forward either. And what if the one with the higher ER has historically outperformed over the long term?
So how do you screen your investments?
