The way to tell is to look at the divergence of the fund's performance from the benchmark index.adamu wrote: ↑Sun Apr 23, 2023 4:37 am Another one is I still don't know how big the triple tax issue really is, as as far as I know there is no info about it from the providers and no decent comparison between funds subject to triple taxation and equivalent funds that aren't (at least, I've not seen one but I've not looked very hard recently).
Shintaro money does this: eMaxis Slim All Country, Tawara All Country, Tawara Developed Markets ex Japan, Rakuten's VT wrap. Shintaro further refines by showing the benchmark minus the fund fee minus the fund operating costs declared in the annual reports (these last two are the "実質コスト"). Then the difference between the dashed line and the actual fund performance is due to the tax inefficiencies, among other things.
TLDR Rakuten's VT has a large divergence from the dashed line. eMaxis Slim & Tawara do not.
